What Sets a Crusher Duty Motor Apart
A standard general purpose motor isn't built to absorb a jaw or cone crusher jamming on an oversized rock. Crusher duty motors use reinforced shafts and extra capacity bearings to handle that kind of shock without failing.
They're also built with higher starting torque, since breaking a jammed crusher loose takes more force than starting a motor under a steady load.
Horsepower and Frame Sizes for Heavy Equipment
This collection runs from 20HP up to 600HP, in large frame sizes up to 587T and beyond for the biggest units. All motors here run on three phase power, in voltages up to 575V.
Speeds of 900, 1200, and 1800 RPM cover different crusher types and gear reduction setups, so filtering by frame and speed narrows things down fast if you're matching an existing installation.
Managing the Startup Load
A motor this size pulls a heavy inrush current the moment it starts, which puts stress on both the electrical system and the crusher's drive components. Pairing your motor with a soft starter smooths that startup and reduces wear on belts, gearboxes, and couplings over time.
Built for Belt Driven Crushers
Many crusher applications run the motor through a belt rather than a direct shaft connection, which puts extra radial load on the motor's bearings. If your setup needs new sheaves or belts to go with the motor, we carry pulleys and sheaves and belts as well.
When Repair Makes More Sense Than Replacement
At this horsepower range, a rewind can often cost far less than a new motor. Our shop handles large motor repair and rewinding in house, and we can help confirm whether your existing unit is worth restoring before you commit to buying new.
