IMA - Integrated Motor Actuator
IMA INTEGRATED MOTOR ACTUATOR
Endurance Technology features are
designed for maximum durability to
provide extended service life.
The IMA is a compact, durable, high force rodstyle actuator with an IP65 rating. The IMA
integrates a servo motor into a ball or roller
screw-driven actuator to provide efficient high
force in a compact lightweight design envelope.
Our patented design allows for easy re-lubrication
without disassembly for extremely long service life.
Built-to-order in stroke lengths up to 18 inches
(450 mm) with your choice of screw technology.
MULTIPLE SCREW TECHNOLOGIES
YOU CAN CHOOSE:
•Ball nuts offer efficiency at
a cost effective price
•Roller nuts provide the
highest thrust and life
ratings available
HIGH POSITIONAL ACCURACY SCREW ACCURACY
Roller Nut ± 0.0004"/ft. ± 0.0102mm/300mm

PEAK REGION is the maximum performance capabilities of the actuator system. Higher peak thrusts are achievable by servo motor
actuator systems, so please consult Tolomatic before exceeding catalog rating.
CONTINUOUS REGION is defined as the RMS thrust and velocity limit that is derived from the thermal limits of the actuator system
to achieve the dynamic load rating of the screw. (Example: Extend and retract under force 100% of the time with no dwells.)

actuator is expressed as
the linear travel distance
that 90% of properly

estimation purposes only.
The underlying formula that defines this value is:

where:
C = Dynamic load rating (lbf) or (N)

CALCULATING RMS THRUST, RMS
VELOCITY AND POWER LIMIT
CALCULATING LUBRICATION INTERVAL
Roller screw actuators have two different operating regions
which must be sized: RMS and peak. Peak operation is the
maximum speed and/or maximum thrust the actuator that does
not factor in dwells. RMS operation is the root mean square
calculation of the entire motion cycle including dwells (time at
rest). It is extremely important to include all dwells (time at rest)
in the RMS calculation. There are instances where peak and
RMS specifications can be exceeded, but must be approved
by Tolomatic. RMS Thrust, RMS Velocity and Power Limit are
calculated using these equations:
√
=√
TRMS =
∑ (T i2 x t i)
∑ (t i)
VRMS
∑ (V i2 x t i)
∑ (t i)
Where:
TRMS = RMS Thrust
VRMS = RMS Velocity
Ti = Thrust during interval i
∑ = sum
i = 1 to n
Vi = Average velocity during
interval i
ti = Time interval i
P = Power limit
P = TRMS x VRMS
(Watts)
(N)
(m/sec)
NOTE: Denominator
represents full cycle time
including dwells. Do NOT
include dwell times in the
numerator.

SIDE LOAD CONSIDERATIONS
The IMA integrated motor actuator is not meant to be used in applications where side loading occurs. Loads must be guided and
supported. Loads should be aligned with the line of motion of the
thrust rod. Side loading will affect the life of the actuator.

INERTIA
IMA actuators require periodic re-lubrication to maintain optimal performance. Below are formulas to help determine lubrication interval.
See IMA User Guide (#2700-4001) for formula definitions, complete
instructions and examples.
24
A brake can be used with the actuator to keep it from backdriving,
typically in vertical applications. A brake may be used for safety
reasons or for energy savings allowing
the actuator to hold position when
un-powered. See page ima_23 for
ordering information.
NOTE: The optional Spring-Applied / Electronically-Released Brake
requires 24V power. Input current

IMA22 - 0.35 Amps;
IMA33 - 0.43 Amps;
IMA44 - 0.67 Amps;

3600-4187_01_TN_IMA-AB-servo.pdf
The IMA is the most rigorously tested Tolomatic product yet
Cutting edge products like the IMA don’t just
fall into place. Over 20,000 hours of testing
were required to prove the design that ships
today. Thermal imaging, dynamic loading and
other state-of-the-art techniques give us the
confidence to stand behind our published
performance data.

IMA - Integrated Motor Actuator
Selection Guidelines
1
2
ESTABLISH MOTION PROFILE
Using the application stroke length, desired cycle time
and loads establish the motion profile details.
OMPARE OPERATING (PEAK) THRUST
C
AND SPEED TO OPERATING REGION
Calculate the application required operating (peak) thrust
and speed and compare to tables on pages ima_8-9. The calculated thrust and speed must fall within the operating region
of the actuator.
3
COMPARE SEVERE DUTY (CONTINUOUS)
THRUST AND SPEED TO SEVERE DUTY REGION
Calculate the RMS thrust and speed required and compare
to tables on pages ima_8-9. The calculated thrust and speed must
fall within the severe duty region. See complete instructions on
page ima_14 for help calculating continuous force.

CONSIDER SCREW/NUT CHOICES
Choose roller nuts for its longer life (see Life graph on
page ima_13) and higher peak loads (see graphs on
pages ima_10 & 11). Ball nuts are cost competitive and more
efficient (see table on page ima_8).
SCREW ACCURACY

VERIFY CRITICAL SPEED OF THE SCREW
Verify that the application’s peak linear velocity does not
exceed the critical speed value for the size and lead of the
screw selected.
ERIFY AXIAL BUCKLING STRENGTH OF
V
THE SCREW (ROLLER SCREW)
Verify that the peak thrust does not exceed the critical
buckling force for the size of the screw selected.
MOTOR WINDINGS & VOLTAGES
Choose motor windings optimized for 230 Vac and 460
Vac voltage busses. The 1 stack motor (MV21-230V &
MV41-460V), available for the IMA22/33, allows strokes between 3 and 6" providing the thrust needed for many applications in a more compact, lighter weight package
8
9
CALCULATE LUBRICATION INTERVAL
See page ima_14 for an overview and IMA Users Guide
(#2700-4001) for complete instructions to calculate lubrication interval.
TEMPERATURE
The IMA is intended to operate in an environment with
an ambient temperature between 50-104°F, (10-40°C).
Performance should be de-rated if the ambient temperature
is above 77°F (25°C). Contact the factory if the ambient temperature does not fit within this range. NOTE: Temperature of
IMA_20
the actuator's body can approach 180°F (82°C) in aggressive
applications. Adequate clearance to ensure actuator's ambient
conditions do not rise drastically should be allowed.
10
BRAKE CONSIDERATIONS
An un-powered IMA will require a brake to maintain
its position if the force on the actuator exceeds Back
Drive Force listed in the table on page ima_8.
A brake can be used with the actuator to keep it from backdriving, typically in vertical applications. A brake may be used
for safety reasons or for energy savings allowing the actuator to
hold position when un-powered. See page ima_23 for ordering
information.
NOTE: The optional Spring-Applied / Electronically Released
Brake requires 24V power. Input current rating:
IMA22 - 0.35 Amps; IMA33 - 0.43 Amps;
IMA44 - 0.67 Amps; IMA55 - 0.66 Amps.

12
CONSIDER MOUNTING &
ROD END OPTIONS
Examine mounting options dimensional drawings on
page ima_15-18. Standard mounting on the IMA are 4 tapped
holes on the front rod end face of the actuator. The Side Mount
option (MST) includes 12 tapped holes, 4 on each side and 4 on
the bottom of the actuator. Other fixed mounting options are the
Front Flange Mount (FFG) and Mounting Plates (MP2). Pivoting
mount options are Front Trunnion (TRF), Rear Trunnion (TRR) and
Rear Clevis Mount (PCD).
Rod End Options include: External Threaded Rod End (MET),
Clevis Rod End (RCL), Spherical Rod Eye (SRE) and Alignment
Coupler (ALC).
NOTE: Regardless of the mounting option chosen, care must be
taken to ensure that the load is guided and in-line with the thrust
rod's line of motion. Misalignment of the thrust rod's line of motion will cause degradation in the actuator's expected life.
13
CONSIDER ENVIRONMENTAL RATING
AND ANTI-ROTATE OPTIONS
The environmental rating for a standard IMA is IP65,
choose IP67 for protection against water and dust ingress.
Choose the Anti-Rotate Option (ARO) if required. Call Tolomatic
at 1-800-328-2174 for help in determining the best actuator for
your application.
