Crusher Duty

Crusher Duty Motors (TEFC) are 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.

Features that make a difference-NEMA Premium Efficiency:

• Oversized roller bearings
• Versatile starting methods-capable of wye/delta, across the line and part winding (12 leads) start
• NPT threaded terminal box
• Class F insulation (Impregnation resin and magnet wire are Class H)
• NEMA design A. All ratings exceed NEMA design C torque
• F1 mounted (F2 convertible). Frames 447T and up can easily be F2 converted by simply rotating the terminal box adapter
• Regreasable ball bearings
• Gasketed conduit box
• Class 1, Div. 2, Groups A, B, C & D – T3, Class 2, Div. 2, Groups F & G – T3C

Inverter Rated:

• 1000 : 1 variable torque
• 20 : 1 constant torque
