Master Line
The motors of the Master line (M line) stand out for
the flexibility of their electrical and mechanical
project.
They are versatile motors with different configurations suitable
for severe environments which demand high resistance and
durability, adapting to different applications.
Their design is easily customized so as to make them
interchangeable with already existing motors, cutting down
operating costs with downtime for motor replacement.
They can also be designed for inverter operation, enabling
accurate speed control, as well as high torques during start.

Manufacturing
Frame
Made of welded steel plate or cast iron, it is the structural part of the
motor, housing, supporting and protecting the active magnetic part of
the motor. With rugged construction, it provides excellent strength
and low vibration levels to the motor.
Frame
Stator
It is the active magnetic static part of the motor. It is a core composed
of pressed silicon steel laminations with slots which house the coils
forming the stator winding. The stator core is mounted directly on the
frame.
Stator
Winding
The winding process adopted by WEG is especially developed for the
voltage and application the motor is intended for. The coils can be
made of round or rectangular copper wire, depending on the motor
voltage. The round-wire coils are normally used in low-voltage
motors, while the rectangular-wire coils are form wound and used in
medium and high voltage motors. The coils of high-voltage motors
are normally insulated with porous mica tape, and the protection
against the corona effect is ensured by the application of conducting
and semiconducting tapes.
Winding
8
Three-Phase Induction Motors - Master Line
www.weg.net
Rotor
It is the rotating component of the electric motor. Basically composed
of the shaft and a pressed silicon steel lamination core.
The slots of the core house the cage or the rotor coils, in case of
wound-rotor motors. The cage can be made of cast aluminum or
manufactured in copper or brass.
The rotor is sized considering the torque required at the start and
operating conditions of the motor.
Rotor
Insulation System
The WEG MICATHERM insulation system is based on the Vacuum
Pressure Impregnation process (VPI).
Using special epoxy resins, this system ensures perfect insulation of
the motor coils, in a process totally free from gases harmful to the
environment.
For many years the VPI process has proved its efficiency and
reliability in rotating electrical machines in many different applications.
The insulation system is applied to machines with voltage of 380 to
15,000 V.
Vacuum impregnation (VPI)
Balancing
WEG uses equipment that allows performing balancing at up to
3,600 rpm. Computerized balancing equipment allows the accurate
balancing of the motors. As a result, WEG motors present very low
vibration levels.
The standard balancing is done in two planes, but WEG can perform
the balancing in three planes when required or specified by the
customer.

Applications
Squirrel Cage Motor
Due to the versatility of the project, the motors of the Master line can be used in different industries to drive machines or
equipment that require variable or constant torque, such as fans, pumps, crushers, conveyor belts, compressors, mills, mixers
and others.
Wound-Rotor Motors
The wound-rotor motors are normally used in loads with high inertia or high resistive torque at startup. They are also used
when starting current limitations are present in the power supply system. They are used to drive loads such as: ball mills,
cement mills, fans, exhaust fans, shredders and rolling mills employed in the cement, mining and steel industries, among
others. They can be supplied with withdrawable (motorized/manual) brush holders or fixed brush holders, according to the
load or operation requirements. The slip ring tracks are made of material with excellent electric conductivity. The wound-rotor
motors with withdrawable (motorized/manual) brush holder present important advantages in terms of maintenance, because
they enable the brushes to be in contact with the slip rings only during the start, minimizing the wear of brushes and slip rings,
thereby extending intervals between maintenance.
Vertical Motors
The motors of the Master line with vertical mounting are designed and manufactured to meet the customer’s requirements so
as to apply them to pumps, crushers, mixers and motors. They can be supplied with rolling bearings or sleeve bearings
(hydrodynamic).
Motors for Explosive Atmospheres
For applications in explosive atmospheres, WEG manufactures motors with specific safety features, able to operate in
locations where flammable materials are handled, processed or stored, preserving human life and ensuring the integrity of
property. The motors of the Master line with Ex-e (increased safety), Ex-n (nonincendive) and Ex-p (pressurized) protection,
motors class I, division 2, according to NEC 500, meet the requirements of national and international standards and are tested
and approved by certifying bodies recognized worldwide.
