WEG’s IEEE 841 motors are specially
suited for Pulp & Paper mills, Steel mills,
Petrochemical Plants and diverse demanding
applications requiring severe duty long life
motors.
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.
