Crushing and screening plants demand the harshest operating conditions from a motor: heavy starting load, high torque, constant vibration and intense dust. The electric motor chosen for these plants must keep the line running without interruption through both mechanical strength and steady torque output.

The Nature of the Crusher Load

Jaw and impact crushers create sudden load swings and high inertia. The motor must have adequate starting torque, and its frame must withstand this vibration. The cast iron frame holds its form under impact and vibration, extending bearing life.

Choosing the Right Speed for Torque

Because high torque is usually the priority in crushing and screening lines, 6-pole (1000 rpm) or 4-pole (1500 rpm) motors are preferred. High torque at low speed turns the crusher shaft effortlessly and balances the load on the belt-pulley system.

Protection Against Dust and Moisture

In field conditions, the IP55 protection class keeps the windings safe against dust and splashing water. Class F insulation withstands the heat that builds under continuous load; the S1 rating makes uninterrupted shift-long operation possible. This trio is indispensable for open-site plants.
