1.12. PHASE
Motors are designed for either single-phase or three-phase operation as indicated. Single-phase motors may be
operated on one-phase of a three-phase power supply with the rated voltage. Operation of a three-phase motor
on a single-phase supply will result in motor damage.
Note: Single Phase is not available in MAC Configurator.
1.13. FREQUENCY
The rate at which alternating current makes a complete cycle of reversals. It is expressed in cycles per second. In
North America 60 cycles (HZ) is the standard while in other countries 50 HZ is more common. The frequency of
the A.C. power supply will affect the speed of the motor.
Many motors designated for operation on 60 Hz power may be operated on 50 Hz power of a lower voltage rating
with resulting decrease in speed and horsepower. Refer to Reliance Electric for details. In accordance with NEMA
standards Reliance Motors will operate with +or- 5% variation in rated frequency with rated voltage. Performance
with this frequency variation will not necessarily be in accordance with performance at rated frequency.
Note: Refer to Voltage Section for non-standard Frequency / Voltage combinations.

1.16. ENCLOSURE
NEMA Enclosures
ODP – Open Drip Proof (available 250-449 frame only)
An ODP motor has openings which allow free flowing air to enter directly into the motor enclosure and around the
windings to provide cooling, these openings are protected against falling objects or dripping liquids. Sometimes ODP
motors are referred to as “open-protected” motors. The ventilating openings are 15 degrees or more from the vertical so
that falling objects or dripping liquids will strike the top of the motor and then roll off the enclosure rather than fall directly
into the inside of the motor. The ODP enclosure is one of the most commonly used standard enclosures. It is normally
used in most general applications where the air is cool, reasonably clean and dry. This enclosure is not good, however, in
applications where the motor is subject to dust or splashing liquids.
TENV – Totally Enclosed Non-Ventilated
A TENV motor is designed to exclude outside ventilating air from contact with the motor’s internal parts although they are
not actually air-tight. The frame and end shields form a solid enclosure that has no ventilating (or external) openings. A
TENV enclosure also has no external fan which means that the heated air inside the motor dissipates heat to the outside
through the motor frame. The exterior of the frame is often heavily ribbed to provide additional cooling surface, since
exposing more heated metal surface to the outside air helps cool the motor faster. Most TENV motors are small in size.
Larger TENV motors are often used for intermittent service because of their lack of ample cooling. This enclosure protects
the inside of the motor against dust, dirt and corrosion and is also good for applications where fan clogging material is
present, like the floating fibers found in textile and paper mills.
TEFC – Totally Enclosed Fan Cooled
A TEFC motor is a TENV motor with an external fan mounted on the shaft which provides additional cooling. This fan
blows air over the outside of the enclosure to aid in removing the heat. As with TENV motors a TEFC design does not
allow outside air to enter inside the enclosure. TEFC enclosures are good in dirty or corrosive atmospheres.
TEAO – Totally Enclosed Air Over
A TEAO motor is a TENV motor that is mounted in a fan application. The driven fan provides the air flow over the outside
of the enclosure to aid in removing the heat. As with TENV and TEFC motors a TEAO design does not allow outside air to
enter inside the enclosure.

The enclosure and enclosure enhancement in IEC terms is a combination of the IP (protection) and IC (cooling) codes.

Motors which include a Hazardous Location will be nameplate marked appropriately based on classification
selected. Any motor which includes a Hazardous Location can also be provided with additional hazardous
location markings on the nameplate (see Nameplate / Labels page). This "Additional Hazardous Location Marks"
selection allows motors to be nameplated with equivalent IEC (Zone) Markings which match the UL or CSA (Div
1/Div 2) Markings. The motor will only include the UL and/or CSA Logo on the nameplate as applicable.

Division classification defines the atmosphere type
• Division 1: the atmosphere is considered potentially explosive under normal conditions
• Division 2: the atmosphere is normally not explosive, but under unusual conditions can become explosive.
Division 1 motors are approved by Underwriters Laboratories Inc. (UL).
UL is a non profit organization that establishes, maintains, and operates laboratories for the examination and testing of
devices, systems, and materials. This marking should be accepted by all locations in the USA. All Division 1 motors will
include the following UL Marking along with appropriate classification.
UL Listing Mark
This is one of the most common UL Marks. If a product carries this Mark, it means UL found that representative samples of
this product met UL's safety requirements. These requirements are primarily based on UL's own published Standards for
Safety. This type of mark is seen commonly on appliances and computer equipment, furnaces and heaters, fuses, electrical
panelboards, smoke and carbon monoxide detectors, fire extinguishers and sprinkler systems, personal flotation devices
like life jackets and life preservers, bullet resistant glass, and thousands of other products.

NOTES:
1.) Division 1 Motors are not marked with Division classification and are suitable for Division 1 and
Division 2 environments per NEC Article 500. These motors are marked only with designated Class, Group, and Temp Code
along with UL Listing Mark and certification.
2.) Factory Mutual (FM) is a similar organization as UL and both provide equivalent type certifications and listings. Since
UL is the approval agency that Reliance Electric Motors are certified by, Reliance Electric does not also have approval by
FM.

Division 2 motors are approved by Canadian Standards Association (CSA).
CSA is the clearinghouse and coordinating body for standards activity on a national level. This marking should
be accepted by all locations in US and Canada.
Certification marks for the U.S. and Canada: A CSA mark with the indicators "C" and "US" or "NRTL/C" means
that the product is certified for both the U.S. and Canadian markets, to the applicable U.S. and Canadian
standards.

1.21. TEMPERATURE CODE
"T" Codes ("Temperature" Codes)
The third result, as mentioned above, of the new U/ L requirements for explosion-proof motors is that all XP motors must
be marked to indicate the maximum operating surface temperature. A "T" Code is used as the Temperature identification
value and it is taken from the National Electric Code. The "T" Code is based on the minimum ignition temperature of the
substances to be found in the hazardous location. (Ignition temperature is when substance will start to burn or explode,)
The code, when marked on a motor nameplate, represents the highest temperature that could be obtained on the motor
surface under any normal or abnormal operating conditions including locked rotor, single phasing or overloading, and is
chosen to be below the ignition temperature of the substance in the hazardous area. The "T" Code designations apply to
motors and other types of electrical equipment subject to hazardous location classification.
For reference, the following is the complete temperature identification code table taken from the National Electric Code
showing the U/L requirements for each class and group for which we label. Since the standard multi-label motor (Class l,
Group D, Class II, Group F and G) meets T3B, this product also meets all the surface temperature codes higher than this,
i.e., T1 through T3B.

1.23. DESIGN LETTER
Design B is the most common three phase General Purpose electrical design. With good
Torque to Current ratios, this motor is suitable for use on a wide variety of applications.
A Design B motor is a squirrel-cage motor designed to withstand full-voltage starting, developing locked-rotor,
breakdown, and pull-up torques adequate for general application as specified in 12.38, 12.39, and 12.40, drawing lockedrotor current not to exceed the values shown in 12.35.1 for 60 hertz and 12.35.2 for 50 hertz, and having a slip at rated load
of less than 5 percent1.
Design C provides a higher level of Locked Rotor torque than Design B with the same level of starting current. The tradeoff in design is usually a lower Breakdown Torque and in some cases efficiency. This design is common on conveyors
where higher starting torque can prevent the need for selecting the next larger Design B rating just to get the load started.
Design C motors are only available as single speed motors with Premium Efficient (XE) designs and are not available, and
are not defined, by NEMA at 3600 rpm, below 5hp at 1800 rpm, and below 3hp at 1200 or 900 rpm.
A Design C is a squirrel-cage motor designed to withstand full-voltage starting, developing locked-rotor torque for special
high-torque application up to the values shown in 12.38, pull-up torque as shown in 12.40, breakdown torque up to the
values shown in 12.39, with locked-rotor current not to exceed the values shown in 12.34.1 for 60 hertz and 12.35.2 for 50
hertz, and having a slip at rated load of less than 5 percent.
Design A usually indicates a special electrical design such as high Locked Rotor or Breakdown torque without the limits
on current dictated by Design C or D. Design A is most commonly seen motors which are derated (Nameplated at a lower
HP than their design) or motors requiring high Breakdown torque during short periods without the high slip associated
with Design D. (i.e. Hydraulic Pump Drives on Injection Molding machines for Compactors). Design A motors are only
available as single speed motors with Premium Efficient (XE) designs in 254-444 frame sizes. Design A is also available as
Torque Max/Crusher Duty design which is selectable on the Rating/Enclosure page. The Torque Max/Crusher Duty option
is available as Energy Efficient (EPAct) E*Master designs and also has additional rules and limitations.
A Design A motor is a squirrel-cage motor designed to withstand full-voltage starting and developing locked-rotor torque
as shown in 12.38, pull-up torque as shown in 12.40, breakdown torque as shown in 12.39, with locked-rotor current
higher than the values shown in 12.35.1 for 60 hertz and 12.35.2 for 50 hertz and having a slip at rated load of less than 5
percent1.
Design D provides an even higher level of Locked Rotor torque than Design C with the same Locked Rotor current limit.
Full Load Efficiency is poor on Design D, however, Design D motors are used on applications where full load is rarely seen
and its ability to efficiently accelerate the load is required. Typical applications are Crane & Hoist, Punch Press and Oil

1.25. SERVICE FACTOR
IEC standards define only a 1.0 service factor.
1.26. DUTY
Duty Cycle is the relationship between the operating and rest times or repeatable operation at different loads. A motor
which can continue to operate within the temperature limits of its insulation system, after it has reached normal
(equilibrium) operating temperature is consider to have a continuous duty (Cont) rating. One which never reaches
equilibrium temperature, but is permitted to cool down between operations is under intermittent duty conditions, e.g. crane
and hoist motors which are often rated 15 or 30 min duty.
Starts and Stops
Some applications requirements require multiple starts/stops per hour. NEMA MG10 sec. 2.7 Application Analysis
addresses load cycling and the application of motors to it. Under Table 2-3 it addresses the allowable number of starts and
minimum time between starts for Design A and Design B motors. All Reliance motors as standard meet the NEMA start
and stop requirements of 2 Cold and 1 Hot consecutive after which motor must cool to ambient.
The number of actual starts allowed is a function of the load inertia reflected to the motor shaft. The one hot and two cold
is a value specified by NEMA when the load inertia is the maximum value the motor can handle. When the load inertial is
lower, the motor can do more starts.
Contact your local Sales Representative with the following information.
§
Basic motor descriptions and applications descriptions
§
WK² Reflected to the motor shaft in lbft²
§
Number of starts per HR/Min. and time running
§
Number of stops per HR/Min. and time rest
§
Method of stopping: Coast to rest, Brake stopping, or Plug reversals
§
The speed torque curve or characteristics of the load.
To calculate the actual number of motor starts allowed take the actual load inertia of the application and multiply it by 2,
then divide this number into the max inertia, then the number of starts can be increased by this ratio.
Example: Assume the max load inertia is 1000 lb.ft.² and the actual inertia is 250 lb.ft.² reflected to the
motor shaft, then the 1 hot and 2 cold becomes 2 hot and 4 cold starts (250x2=500, 1000/500=2). There is
always a coast to stop between start required.

2.8. STARTING METHOD
Standard Start
Motor will be provided either Wye or Delta connected based on rating and is suitable for Full Voltage
starting.Motor will be suitable for reduced Voltage Starting to 80% if Premium Efficient (XE) design is selected.
Wye Start – Delta Run
Not available on multispeed motors.
If required for a dual voltage motor then, based on voltages specified, the winding connection will display what the motor
capability will be. If dual voltages are a ratio of 1.73 then motor will be suitable for wye start – delta run on “low volts
only”. If dual voltages are a ratio of 2 then motor will be suitable for wye start – delta run on both “high and low volts”.
Example: If 220/380 volts (1:1.73 ratio) is selected along with wye start – delta run then motor is suitable for wye start –
delta run on the 220 volt connection only (6 leads required).
-orIf 230/460 volts (1:2 ratio) is selected along with wye start – delta run then motor is suitable for wye start – delta run on
both the 230 and 460 volt connections (12 leads required).
A method of starting a motor at rated voltage but drawing locked rotor current and producing reduced Locked Rotor
Torque this starting method provides lower starting torque than a straight delta connection. Once the load and motor have
been started, the wiring connection will then be switched from the WYE connection to a DELTA connection to deliver full
torque.
Part Winding Start
Not offered as standard option for 180-280 frame sizes.
If required for a dual voltage motor then customer must advise if winding connection for Part Winding Start is required on
“low volts only” or on both “high and low volts”.
Example: If 220/380 volts is selected along with part winding start then. . .
The motors will only be suitable for part winding start on the 220 volt connection if “Low Volts Only” is selected (9 leads
required).
-orThe motors will be suitable for part winding start on both the 220 and 380 volt connection if “High and Low Volts”
selection is made (12 leads required).
Wiring connections are arranged for starting by first energizing part of the primary winding and subsequently energizing
the remainder of this winding in one of more steps. The purpose is to reduce the initial value of the starting current drawn
or the starting torque developed by the motor. A standard part winding start induction motor is designed so that one-half
of its primary winding can be energized initially and subsequently the remaining half can be energized, both halves then
carrying the same current.

3.1. MOUNTING FLANGE - DE
NEMA Mounting flanges
None – No flange provided motor will be foot mounted.
C-Face – A type of flange used with close coupled pumps, speed reducers, and similar applications where the mounting
holes in the flange are threaded to receive bolts. Normally the C-face is used where a pump or similar item is to be
overhung on the motor. The “C” type flange is a NEMA standard design and available with or without feet. C-face
designation is identified by including a “C”suffix in the frame size.
D-Flange- A special end shield with holes for through bolts in the flange and is primarily used for mounting the motor on
gear boxes or bulkheads. Standardized sizes are available for frames 182T-445T frames. The “D” type flanges are not
threaded and the bolt holes extend beyond the motor frame. D-flange designation is identified by including a “D” suffix in
the frame size.
P-Base - A special mounting similar to a “D-flange” except with a machine fit tenon recessed instead of protruding. This
flange configuration is usually associated with pumps with axial thrust loadings. The below tables identify maximum down
thrust capabilities based on various bearing life expectancies. P-Base designation is identified by including a “HP” or “LP”
suffix in the frame size. “HP” designates normal thrusts capabilities and “LP” designates either medium or extended thrust.

3.12. BASES
Adapter/Transition Base - Used to raise the shaft height of the new motor. In the NEMA 140 to 449T frames this
represents a base which allows the use of the current standard T- Frame, to mount where a U-Frame has been used. i.e. a
10HP 1800 RPM motor is in a 215T, where the previous generation 10HP 1800RPM rating was a 256 U-Frame. Based on
NEMA standard mounting dimensions, the Transition base will mount where the previous motor was mounted and provide
the correct mounting holes for the 215T frame. For the Large AC and DC motors the Adapter/Transition base is usually a
custom built product to meet the specific changes required and must be user defined.
Soleplates - Used on larger motors to provide a machined mounting surface where a common base with the driven
equipment is not used. These plates include mounting holes for the specific motor frame and are often grouted into a
concrete pad. Soleplates are available as either a one piece or 2 piece design. The one piece design will insure relative
alignment of the two rails, while the two piece offer lower cost.
Slide Base / Rails - Used to adjust tension on belt driven applications. (Only available if Drive Method = Belted)
Slide bases are offered as single adjustment bolt on 210T and smaller frames, and Heavy Duty double adjustment designs
on larger motors. Most 447 frames and larger require a special two piece design.
3.13. NON-REVERSING RATCHET
This is a clutch mounted on the opposite drive end of the motor. Motor direction of rotation must be defined based on
reference point facing the Opposite Drive End (see Mounting/Flange Page). A direction of rotation and phase sequence

Insulation Design Life
The insulation design life for a NEMA size AC Motor is normally established to be 10 years. Motor manufacturers based
this design life on the IEEE 117 Motorette Test Procedure.
The ultimate temperature of an insulation system is the maximum total temperature at which the system can be operated
without adversely affecting the design life of the motor. The insulation class rated temperature is not the motor rise
temperature, although there is a relationship. The total temperature allowable for the specific insulation system includes
the ambient, rise, and hot spot temperature. The temperature rise of the motor is the number of degrees which the insulated
motor winding heat up due to the power losses characteristic of the motor design.
A motor’s operating temperature can be affected by load, volts, voltage balance, bearings and lubricants, duty cycle, radial
and axial loading, mounting, enclosure, ventilation, and ambient temperature. It is these application considerations, not the
insulation system that affects the motor’s operating temperature. Operation of the motor at a total temperature that exceeds
the maximum rated temperature of the insulation system can adversely affect the motor life. As a general rule of thumb,
each 10°C increase in total temperature over the maximum permissible to the motor insulation system halves its life.

Action Guide
Med AC Motor Configurator
4.2. EPOXY INSULATION
This is for motors that are used in environments that have extreme moisture, corrosive fumes, chemicals, etc. and will be
treated with epoxy varnish – Type E. The motor’s insulation system is then often referred to as BE or FE, indicating a Class
B or Class F system with the same maximum allowable temperatures as indicated by the Class of insulation but with an
epoxy varnish.
4.3. TROPICALIZED
This is a treatment of MIL Spec approved fungicidal varnish – Type J. The motor’s insulation system is then often referred
to as BJ or FJ, indicating a Class B or Class F system with the same maximum allowable temperature as indicated by the
Class of insulation but with a fungicidal varnish. This can be provided for motors that are used in environments that
require tropical, fungicidal protection. Motors that will be stored for long periods of time prior to startup or that are
shipped over seas may require tropical or fungicidal protection.
4.4. INSULATION VPI
This system is an epoxy-encapsulated, Vacuum Pressure Impregnated (VPI) system. It starts with a coated magnet wire
that has improved insulation capabilities. The entire wound stator is then Vacuum Pressure Impregnated with a multiple
resin compound. The high thixotropic 100% solids epoxy resin material and the VPI process provide a virtually void-free
winding. The resins are thick and provide superior electrical resistance properties, greater mechanical strength, and better
heat dissipation for a cooler running motor with longer motor life. Each conductor is surrounded by cured resin and locked
into position. Winding end-turns are completely covered and filled with resin so they can withstand vibration and
movement without cracking. They are effectively sealed against contamination. Better heat dissipation throughout means
the elimination of hot spots. The net result is a superior insulation system that provides longer motor life.
Note: Insulation VPI suitable for IEEE 429 includes two VPI cycles.

5. BEARING / SEALS / LUBRICATION
5.1. BEARING TYPE
Ball Bearings – Single row, deep groove (Conrad) with C-3 fit. This is a standard bearing used in virtually all types and
sizes of motors. It exhibits low friction loss, is suited for high speed operation and is compatible in a wide range of
temperatures.
Roller Bearings – A special bearing with cylindrical rollers capable of handling belted applications, that exceed the
capacity of a standard ball bearing in a similar application. Roller bearings are not suitable for coupled or direct service.
Roller bearings require radial loading and therefore are only available for belted applications. The lack of radial loading
would result in premature bearing failures. Also roller bearings are usually supplied on the drive end of the motor in
conjunction with a ball bearing on the opposite drive end.
Thrust Bearings – A special bearing that is capable of handling axial thrust. Thrust bearings are only provided on Vertical
P-Base Motor which requires medium or extended “LP” thrust capabilities since the thrust bearing requires a minimum load
to also prevent premature bearing failure. The thrust bearing is generally provided on the opposite drive end of the motor
(to meet API 610 construction) in conjunction with a ball bearing on the drive end of the motor.
5.2. BEARING ENHANCEMENT
Open – Open bearings with Reliance Positive Lubrication System PLS is standard on XT
Motors and all motors with PLS. This enhancement results in lower operating temps (5-9 degrees C)
and allow for fresh grease to be pumped directly into the bearing balls.
This provides:
Cooler Bearing Operating Temperatures - Minimal friction which allows for cooler bearing operation.
Positive Lubrication/Relubrication in any Mounting Position - Exclusive grease channeling window with
minimum grease path entry, channels grease directly into bearing track and avoids premature relief out
the shaft bore or drain plug.
Minimizes Corrosion – Small clearance on either side of grease window uniformly distributes grease to
both in board and outboard reservoirs to protect bearing surfaces during motor storage, idle times and
start-up. Bearing system is completely greased during motor assembly.
Restricts Inboard Contaminations – Inner bearing cap with anti-churning vanes and close running shaft
tolerances minimizes contaminant entry into bearings, and grease migration into motor.
Prohibits Overgreasing During Lubrication/Relubrication – Grease relief port accurately indicates
completion of lubrication/relubrication. (If port is plugged during lubrication, PLS design will relieve
grease along the shaft).

RELIANCE PLS - Positive Lubrication System OPEN BEARING
CONSTRUCTION
Single Shielded – This construcation is standard on non-XT frames 180T thru 320T. A shieldedbearing is also a variation
of the Conrad bearing and is very similar to the sealed type bearing except that the shielded bearing has metallic rather
than non-metallic shield. The metal member is secured to the outer race with a close running clearance to the inner race. A
shielded bearing can be relubricated.
Advantages:
1.) Retains the lubricant at the rolling elements regardless of the chamber fit
2.) Provides relubrication to the balls by the slinger feeding of inner race.
3.) Eliminates large particles from getting into the rolling elements at instillation and in operation.
Disadvantages:
Excessive pressure with no relief provided can force the shield against the cage or balls, thereby,
eliminating regreasability or causing immediate failure.
Double Shielded – This construction is available for 180T to 449T. A shielded bearing is also a variation of the Conrad
bearing and is very similar to the sealed type bearing except that the shielded bearing has metallic rather than non-metallic
shield. The metal member is secured to the outer race with a close running clearance to the inner race. A shielded bearing
can be relubricated.
Advantages:
4.) Retains the lubricant at the rolling elements regardless of the chamber fit
5.) Provides relubrication to the balls by the slinger feeding of inner race.
6.) Eliminates large particles from getting into the rolling elements at instillation and in operation.
Disadvantages:
Excessive pressure with no relief provided can force the shield against the cage or balls, thereby,
eliminating regreasability or causing immediate failure.
Note: Double Shielded Bearing enhancement is only available with Chevron SRI#2 and Exxon Polyrex EM grease.
Sealed - This construction is available for 180T to 360T and means that the motor will be supplied with actual sealed
bearings.
Note: Sealed Bearing enhancements is only available with Chevron SRI#2 and Exxon Polyrex EM grease.

Sealed Construction – This is used when shielded bearings are not available Bearing Enhancement means that the motor
will be supplied with open bearings and that the bearing cavities on both sides of the bearing are packed with grease and
sealed by inner cap. The normal grease entry and outlet openings are plugged and plugs are staked in place. In addition a
nameplate is mounted on the motor reading Do Not Lubricate.
This feature is only available on Motors with Open Ball Bearings on the Opposite Drive End. This feature also requires the
enclosure enhancements of XT features or 841XL. ODP Motors require the Bearing Enhancement of Open.
5.3. BEARING L10 LIFE
L10 life is a statistical expectation of bearing fatigue life. It represents a point at which 10% rate of failure can be expected
for a given bearing run at the same speed with constant load. The average bearing life is 5 times the L10 life. L-10 (rated
life) is limited to fatigue endurance life only. This does not consider factors such as lubrication, temperature,
contamination, excessive misalignment and OHL (Over Hung Load), etc. Most bearings fail for reasons other than material
fatigue.
Direct or Coupled Duty
Reliance motors as standard meet 100,000 hours (11.4 years) direct or coupled duty L10 life.
Belted Duty
Reliance motors as standard meet 17,500 hours (2 years) for NEMA belted duty applications using standard ball bearings.
A roller bearing is available as an option for the DE and will increase the L10 life of the motor. If special belted application
is required or a calculated bearing life of a motor is required then the following information must be provided.
1. Motor sheave diameter
2. Driven sheave diameter
3. Center distances of sheaves

with an alemite fitting in the inlet, a plug in the outlet, a special lubrication nameplate, sealed lead entry into the frame and
insulation system and leads that are compatible with most lubricating oils. THIS MOTOR WILL ALSO SHIP WITH
BEARINGS LUBRICATED WITH GREASE TO ALLOW FOR IMMEDIATE OPERATION. (If an auxiliary conduit box is
required, sealed leads will also be provided for that box) Lubrication nameplate and tag attached to the motor reads This
motor is built with grease lubricated bearings. This motor is also constructed to permit field conversion to oil-mist
lubrication at a later date. In order to make this conversion, bearings must be thoroughly cleaned of all grease (or replaced
with new, ungreased bearings), alemite fittings removed and all oil-mist components must be installed. This conversion is
the responsibility of the end-user.

9. TEMPERATURE DETECTION
RTD - A Resistance Temperature Detector (RTD) sensing element consists of a wire coil or deposited film of pure metal.
The element’s resistance increases with temperature in a known and repeatable manner. RTDs exhibit excellent accuracy
over a wide temperature range and represent the fastest growing segment among industrial temperature sensors.
Winding RTD - Reliance default Stator (Winding) RTD package when selected would be six (two per phase) 100 Ω
Platinum single element RTD’s. 10 Ω Copper and 120 Ω Nickel are also available.
Bearing RTD - Reliance default Bearing RTD package when selected includes a three wire, single element, 100 Ω Platinum
RTD with its own junction box with terminal strip mounted at the motor bearing housing.
Thermistor - A thermistor is a resistive device composed of metal oxides formed into a bead and encapsulated in epoxy or
glass. A typical thermistor shows a large negative temperature coefficient. Resistance drops dramatically and non-linearly
with temperature. Sensitivity is many times that of RTDs but useful temperature range is limited. Some manufacturers offer
thermistors with positive coefficients. (PTC)
Thermistors require a solid state control relay which is usually mounted in the Motor Control Center. This relay may be
purchased with the Motor and shipped separately, or purchased separately by the Customer. Not all Thermistors are
compatible with all relays, therefore the Customer should insure equipment purchased is compatible.
The Reliance standard offering is a set of three Power Control MotoGard Thermistors, but we also use Siemens
Thermistors as standard for IEC motors and as an option for all others since they allow for a wide selection in control relay
options (two or more input channels, 220-240V input volts, etc.)
Thermostats - The selection of thermostats will automatically preset the standard quantity provided, however, if available
additional options for quantities will be shown in the drop down selection for quantity.
All Normally Closed thermostats are connected in series internally to the motor and provided with 2 leads exiting either the
main or auxiliary conduit box as selected.
All Normally Open thermostats are connected in parallel internally to the motor and provided with 2 leads exiting either the
main or auxiliary conduit box as selected.
A Normally Closed Circuit is where the thermostat(s) are connected in series with the holding coil of the magnetic switch.
When excessive heat occurs it causes the thermostat to open the circuit of the holding coil of the magnetic switch. This
opens the switch and stops the motor.
A Normally Open Circuit is where the thermostat(s) are connected in series with an electric lamp, bell, or other signal
device. In the event when overheating occurs, the thermostat will close the circuit thereby operating the warning device.
This style is not available for Division 1 or 2 motors.

10. SPACE HEATER
Space Heaters are generally used to prevent damage to the motor windings and internal parts which can be caused by
moisture condensing within the motor. Premature motor winding failure can result if moisture or condensation is allowed to
settle within the motor frame. Modern non-hydroscopic insulation systems are highly resistant to moisture, however, are
not 100% effective if a large amount of water is present. Internal parts can also be damaged by corrosion or oxidation
caused by the presence of excessive moisture. Space Heaters may also be used for other reasons such as to keep the
bearing grease warm during frigid temperatures.
Condensation can form in a motor due to the inherent moisture content of the earth's atmosphere and the heating and
cooling cycles of a motor. The characteristic of air is such that warm air will hold more moisture than the same quantity of
cooler air in the same pressure. The air inside of a running motor is warmer and thus, less dense than the air outside of the
motor. When the motor is shut down, the air within it will cool down and the volume of air will decrease (become denser).
As the air volume decreases, air is drawn in from the outside to equalize the air pressure. This is known as motor
“breathing”. As the moisture laden air within the motor is cooled below a certain temperature (the dew point) and the
pressure is equalized, condensation will begin to form on the windings and internal parts of the motor.
Motors operating outdoors are especially susceptible to internal condensation since this condition can generally be
anticipated when the ambient temperature is 50 degrees F or less. Motors which are subjected to the above conditions and
to a continual running and idle cycle can experience a sufficient collection of internal condensation to cause a premature
winding failure.
The space heaters which are commonly used to prevent condensation in motor applications are basically resistant wire
heating devices. They are used to maintain the internal motor air temperature above the dew point (Temperature at which
water will condense from air which is being cooled at a given pressure and water vapor content). The heater is energized
while the motor is not in use.
The typical Reliance space heater construction, prior to 1988, was to provide a multiple number of cylindrical, metallic
cartridges in the front end (ODE) of the motor. These heaters would typically operate at temperatures in excess of 200 deg
C. Hot spots would be created, which led to several potential problems. The bearing grease could get too hot and cake.
Also, the heater, if operated at maximum capacity, could fail prematurely. To prevent premature heater failure, Reliance
derated a higher rated voltage heater to operate on a lower voltage value (Example: 240 Volt heater to operate at 120 Volts).
In addition, Reliance offered a 200 deg C sheath temperature heater, to reduce the likelihood of hot spots. Some customers,
recognizing the potential problems, would include either or both the derate or the low temperature heater concept into their
specifications.
Because of this many customer specifications, or time honored customer preferences, request the use of space heater
operated at half voltage. (Example: 240 Volt heater to operate at 120 Volts). Due to the uniform operating temperature,
this is not needed for the strip type heater. However, for this request, Reliance will provide (2) space heaters connected in
parallel.
The type of space heater used since 1987 and currently by Reliance is a strip heater, which is a non-metallic flexible heating
element. The heater is mounted (strapped) directly on and wrapped approximately 270 degrees around the coil head at the
opposite end from the connections (front end or ODE of the motor). The space heater meets 150 deg C max sheath
temperature specification and operates at approximately 160 deg C. This ensures uniform distribution of heat transfer
through the coils to both ends of the motor and eliminates the potential for hot spots. This type of heater also requires no
additional mounting hardware. Repairs and modifications can be achieved by lashing a new heater to the coil and coating
with spray varnish to secure the lashing. The space heaters provided are approved by UL and CSA.
As standard, a tag will be attached to the motor which identifies the voltage and wattage of the space heater.

14. TEST / SERVICES
14.1. ROUTINE WITH REPORT
All Reliance Motors receive a routine test as standard prior to shipment.
This selection provides for a copy of this report to be sent to the sold to address as shown on the order.
A copy of the routine test report with vibration data is supplied with the motor in accordance with IEEE 841 as standard
when 841XL is specified (see Enclosure Enhancement on Rating/Enclosure page). If, in addition, a copy is also required to
be sent to the sold to address for a 841XL motor then this selection along with “Mechanical Run/No Load Vibration” test
must be made and both of these will be provided at no additional charge.
Routine Test Parameters:
1.) Measurement of winding resistance in ohms correlated to 25 deg C
2.) No-load reading of current and speed at normal voltage and frequency.
3.) Current input value at rated frequency with rotor at stand still (locked rotor test). Locked Rotor testing is done as single
phase and presented as calculated 3 phase current (amperes).
4.) High-potential test (pass or fail):
1000 volts + 2 times rated volts for 1 minute
1000 volts + 2 times rated volts x 1.2 for 1 second
5.) Vibration is measured and compared against engineering specification limits based upon the order. This is a pass or fail
test and is not a reported value.
Routine Test Procedure:
The winding resistance check test, surge check test and winding high potential test are taken after the
motor winding has been completed and prior to the final check test being performed.
Once the motor is fully assembled with bearings greased the final check test is performed. The motor is suspended by an
overhead gantry system equipped with isolation springs. This procedure isolates the motor from the surrounding
environment in accordance with NEMA MG-1 section 7.06.1 “Resilient Mounting” testing standards and allows us to
perform an accurate undampened vibration check test on the motor. The motor is connected directly to a three-phase
power source. The power source is an MG (motor-generator) set designed to provide clean, sine wave power under precise
hertz and voltage control. The motor-generator set is located directly adjacent to each assembly line test stand in order to
minimize any effects of voltage drop.
Five accelerometers are attached to the motor and mounted in the following positions: 1) Drive End
Axial, 2) Drive End Horizontal, 3) Drive End Vertical, 4) Opposite Drive End Horizontal,
5) Opposite Drive End Vertical.
The motor is tested in a locked rotor condition by applying single phase power to the motor for a short duration of time.
Then motor is run under a no load condition. During both the locked rotor and running conditions, current and associated
voltage readings are taken on the motor and compared to engineering design specifications. Ambient temperature
conditions are also recorded. Winding resistance measurements are also made prior to the start of the test.
- 81 Test / Services
Action Guide
Med AC Motor Configurator
While operating in the no load running condition a vibration check test is made. A multi-channel vibration analyzer
performs a vibration sweep from 0 to 2 KHz. An 800 line data sample is taken and compared to engineering design
specifications. If engineering vibration specifications require tighter resolution then multiple data samples are taken over
various frequency ranges in order to achieve the desired resolution.
Vibration signature data is captured and compared to engineering limits based upon the order specifications requirements.
After the test is complete and the motor has passed all engineering specification limits the motor is approved for shipment.
Routine Test Reporting:
The routine test report format is in compliance with IEEE standard 112 Appendix A standards.
Report of routine tests for induction motors lists the following:
Heading Information
The heading of the routing test report includes the date of the test, Reliance order number, customer name
address and customer purchase order number.
Nameplate Data
This section of the test reports include the primary information on the motor nameplate including horsepower,
calculated slip speed, phase, motor type, hertz, voltage etc.
The “Temperature Rise” field is generally the maximum allowable temperature allowed by NEMA for this specific
insulation class and service factor of the electrical design. If specifically requested on the order this field is used
to define a specific allowable maximum temperature. This is NOT a measured temperature rise as may be implied
by the title block nor is it the engineering calculated or expected temperature rise for this motor design.
Notes Field
This field is generally used to reference duplicate machine performance data such as three phase locked amps. It
is also used for any specific engineering comments as may be required by the order specification.
Test Data Block
“G” Number. Each motor has a unique serialized number or “G” number starting with 001 and ranging up to the
maximum number of identical units on the order . The unique G number follows the sales order number on the
motor nameplate and is used to tie specific test data to a specific individual motor.
No Load Volts, Hz, RPM & Amps: Voltage and current data is the actual measure voltage and amps taken during
the no load test. The hertz and synchronous speed are the design hertz and speed values for this rating (not
measure).
1 Phase Locked Rotor Volts, Hz & Amps: Voltage and Amps data is the actual measured voltage and amps
takenduring single phase locked rotor testing. The hertz value is the design value for this rating (not measured).
Calculated 3 Phase LRA: This is the calculated three phase locked rotor amps based upon the actual test results
from the single phase locked rotor voltage and amps results.
High Potential Volts: The voltage at which the motor passed the high potential test.
Winding Ohms: This is the actual measured winding resistance taken during the final check test and if necessary
corrected to reflect a 25 degree C ambient.
Resistance temperature degree C: A Celsius temperature of 25 degrees is considered standard ambient conditions.
The actual ambient temperature is capture and winding resistance temperatures are correlated to 25 degrees if the
actual ambient temperature varies from this value. The actual ambient condition is not recorded on the routine
test report.

14.2. MECHANICAL RUN / NO LOAD VIBRATION
Routine Test Report with Vibration Data:
With this selection, the routine test report can be provided to include the motor vibration data.
The routine test report with vibration data fully complies with IEEE 841 test and reporting requirements. A copy of the
routine test report with vibration data is supplied with the motor in accordance with IEEE 841 as standard when 841XL is
specified (see Enclosure Enhancement on Rating/Enclosure page). If, in addition, a copy is also required to be sent to the
sold to address for a 841XL motor then this selection along with “Routine with Report” test must be made and both of
these will be provided at no additional charge.
Vibration Procedure and Reporting:
Vibration data is reported at 1)Base Speed, 2) Twice base speed, 3) Twice line frequency, and 4) the overall frequency
range.
The frequency table below gives examples of the reporting frequencies for the above points for two, four and six pole
machines (3600, 1800 and 1200 RPM).
These data points are selected due to their significance relative to the overall vibration of the motor.
The primary vibration component at base speed is residual unbalance of the rotating assembly. This iscontrolled with rotor
balance and straightness of the rotating assembly.
Vibration levels at twice base speed are indicative of alignment of the rotating assembly within the stator winding.
Vibration levels at twice line frequency are induced by magnetic field flux changes and slot harmonics which are
characteristic for that specific electrical design.
Vibration levels at other frequencies are relatively insignificant to the overall motor vibration performance.
An overall vibration level is reported for the entire frequency range tested. The typical frequency range tested is 5 to 2000
Hz. This data is reported as a peak measurement in velocity as inches per second.
Data points are reported for each accelerometer position and expressed in terms of both displacement(inches) and velocity
(inches per second).

14.3. 3 PHASE LOCKED ROTOR
Routine Test Report with 3 phase Locked Rotor:
This selection provides an actual 3 Phase Locked Rotor test to be performed on motor instead of the standard single phase
locked rotor test which is normally performed with a Routine Test.
14.4. COMPLETE TEST
Complete Test Parameters:
1.) Full Load Heat Run
2.) Temperature Rise at full load
3.) Winding Resistance
4.) Rated Full Load Slip
5.) No Load Current
6.) Breakdown Torque
7.) Locked Rotor Torque-Amps
8.) High Potential Test
9.) Efficiencies and Power Factor @ 100%, 75%, and 50% load
10.) Includes Speed/Torque Curves which indicate Locked Rotor, Pull Up, Breakdown, and Full Load Torques.
Complete Test (Heat Run) Procedure:
The complete test is performed on the dynamometer and includes the motor being temperature stabilized under a full load
operating condition.
Thermocouples are installed in the motor to monitor temperature during the test and removed following the test. The motor
is connected directly to a three-phase power source. The power source is an MG (motor-generator) set designed to
provide clean, sine wave power with precise hertz and voltage control. Actual test duration times vary but are generally 8
to 12 hour range for a single speed sine wave motor test.
The winding temperature is measured by winding resistance after the motor temperature has fully stabilized. A ten point
plot back technique is used to record temperature as the motor cools. This data is used to extrapolate a resistance data
point at the time the motor was turned off line.
Performance test measurements are taken at 1/4, 1/2, 3/4, 4/4, 5/4 and 6/4 load points to determine the speed, torque,
current, power factor and efficiency values.
A locked rotor test is also performed. The locked test is performed by using a mechanical locking device secured to the
motor shaft to prevent shaft rotation.
The motor is allowed to cool. After the motor has sufficiently cooled, motor torque measurements are taken to determine
the pull up and break down points of the speed torque curve. This data combined with the locked rotor torque and full
load torque points defines the shape of the speed torque curve.

6. Efficiency and Power Factor at 50%, 75%, and 100% load
7. Speed/Torque Curves included on Reliance’s standard format
14.5. NOISE TEST
Noise Test Procedure:
Actual motor noise testing is performed with the motor being placed in an anechoic chamber. This chamber provides a
free-field acoustic-testing environment. All of the sound emanating from the source is essentially absorbed at the walls of
the anechoic chamber. Hence, there are no sound wave reflections and the spatial sound radiation pattern of a source may
be determined. An anechoic chamber may be described as an “echoless” or acoustically “dead” room. The Anechoic
chamber is located at our motor research facilities in Greenville, South Carolina. This chamber meets the requirements of
IEEE No. 85 “Test procedures for noise measurements on rotating electrical machinery” and is also suitable for making test
conforming to “MIL-N-17060C”, the U.S. Navy shipboard electric motor specification.
Power is applied to the motor and the motor is run in a no load condition. Sound pressure measurements are taken at
three-foot measurements around the motor. Sound pressure is a fluctuating pressure super-imposed on the static
atmospheric pressure in the presence of sound waves. A different sound pressure level may be measured if the same
noise producing device is located in a different environment. The reference pressure used is .0002 microbars which
corresponds to zero on the dB scale applied to sound pressure levels. A specific sound pressure level in dB is not equal
to the same dB value in sound power.
Sound power is a measure of the total air borne acoustic power (energy) generated by a noise source, expressed on a
decibel scale referenced to some standard. Usually 10 to the minus twelve watts acoustic power is equivalent to zero dB.
Sound power levels can not be measured with instruments, but must be calculated from sound levels and correction
factors.
Noise Test Reporting:
Test results are reported in a standard test format “Report of Noise Tests for Induction Motor”. Sound pressure noise
test data dB (decibels) measurements are reported for overall and for specific octave band levels. All dB values are unweighted except for the “A” overall weighted value. The overall “A” weighted measurement is calculated in compliance
with ANSI S1.4- 1971 standards. The test report includes the following:
1. Nameplate data
2. Sound Pressure at 3 feet in dB weighted for overall A scale and unweighted
3. Sound pressure at 3 feet in dB for octave bands (31.5), (63), (125), (250), (500), (1000), (2000), (4000), (8000)

14.6. POLARIZATION INDEX TEST
Polarization Index Test Procedure:
The polarization index test measures the insulation resistance for rotating machinery rated 1HP or greater. Testing is done
per the latest revision of IEEE #43. Polarization index is the ratio of a 10 minute resistance to the 1 minute resistance reading
with a constant test potential of 500 volts being applied to the motor winding. Resistance measurements are recorded in
mega ohms.
IEEE 43 Recommended Practice for Testing Insulation Resistance of Rotating Machinery.
The measured insulation resistance of a motor winding will normally increase with the duration of application of the direct
test potential. The measured resistance of a dry winding in good condition may continue to increase for hours with
constant test potential continuously applied; however, a fairly steady value is usually reached in 10 to 15 minutes. If the
winding is wet or dirty, the steady value will usually be reached in one to two minutes. The slope of the curve is an
indication of insulation condition. The polarization index is the ratio of the 10 minute resistance value to the 1 minute
resistance value. The polarization index is indicative of the slope of the characteristic curve (resistance on the y axis
versus time on the x axis using a xy log scale). The polarization index may be useful in appraisal of the winding for dryness
and for fitness for over potential test. The 1 minute insulation resistance is useful for evaluating insulation condition where
comparisons are to bemade with earlier and later data, similarly obtained. Insulation resistance of a winding is not directly
related to its dielectric strength.
The IEEE recommended minimum value of polarization index for class B and F motors is 2.0.
Polarization Index Test Reporting:
The polarization test and index is reported for IEEE 429 Megger Test as follows:
Insulation resistance is corrected to 40oC
1. At one minute
2. At ten minutes
3. Polarization Index = ratio of ( ten / one ) minute
14.7. CALIBRATION TEST
Calibration Test Procedure:
The calibration test is performed on the dynamometer and consists of no-load, 1/4, 1/2, 3/4, 4/4, 5/4 and 6/4 load test
measurements of speed, torque, current, power factor and efficiency at rated voltage. This is not a heat run and the motor
is not brought up to its full operating temperature. Expected motor temperature rise data is provided based upon test
results from a previous test results of the same rating. Thermocouples are installed in the motor to monitor temperature
during the test and removed following the test. The motor is connected directly to a three-phase power source. The power
source is from an MG (motor-generator) set designed to provide clean, sine wave power with precise hertz and voltage
control. Actual test duration time vary but are generally 4 hours.
Calibration Test Reporting:
Calibration test results are reported on the standard tabulated performance data sheet and
performance
curve format. The actual sales order number ( ID ) tested will appear in the Reliance Electric S.O. data
block and the remarks section will specify “Test Data”.
Winding resistance measurements are adjusted to 25oC ambient temperature.

14.8. IMMERSION TEST
This test is available only when VPI insulation system suitable for IEEE 429 is specified (see Insulation page).
This test is for Sealed/Encapsulated winding conformance.
This test consists of totally submerging a finished wound stator core in an immersion tank which is filled with a
water/wetting agent solution. While submerged, the stator is given a 10 minute Polarization Index Test at 500
volts, DC and a High Potential Test at 1.15 times the rated line-to-line
rms voltage for 1 minute. Test procedures per NEMA MG1-1993-12.62.
