Frequently Asked Questions

Why a crusher-duty motor instead of severe-duty?

Crusher duty adds high breakaway torque and reinforced mechanicals to start and survive shock loads - jams and rock impacts - that severe-duty motors aren't rated for.

What frame and shaft options are available?

Crusher-duty motors use oversized shafts and heavy frames; match the frame, shaft, and mounting to your crusher's drive.

Are these available in high horsepower?

Yes - crusher applications commonly run 100–300+ HP. We stock a broad HP range.
