Severe Duty -
Three-Phase
Motors
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 a
superior cooling system and solid feet for
cool operation and lower vibration and
noise extending the life of the motor.
*Inverter Rated:
1000:1 for variable torque
20:1 for constant torque
* Frame 586/7 250HP and up 6:1 CT and 1000:1 VT
* Insulated housing standard on L447/9T and above
