Severe Duty – Three-Phase Motors Crusher Duty
TEFC - NEMA Premium
Designed for the most demanding crusher
applications. These motors are designed for
horizontal and vertical mounting and have
exceptional high starting and breakdown torques.
WEG’s W22 cast iron platform has an improved
cooling system and solid feet for cooler operation
and reduced vibration and noise, extending the life
of the motor.
