low speed mill drives

Milling Energy intensive and high maintenance

THE LOW SPEED MOTOR SOLUTION Due to the high torque required by the mill, low speed motors are generally synchronous machines. The mill is a low dynamic system therefore a brushless synchronous machine is best suited for this appliion. Brushless synchronous motors have no wearing parts, and the AC/ AC excitation power is kept small.

LSSM = Low Speed Synchronous Motor Drive Operation

In the world of mining and milling the "electrical term" LSSM stands for "Low Speed Synchronous Motor" and usually means a mill where the motor rated speed is in the range of 10 RPM, the same speed as the mill turns. A high speed motor can run at 900 RPM and uses a gearbox to turn down the speed.
