dual motor grinding mill drive synchronous motor

grinding mill,the SAG mill with the dc drive. The ac synchronous motors used in the gear and gearless drives have a higher efficiency than the dc drive. Thus: for large motor horsepowers, the efficiency would affect the operating cost of the operation. Typically, the overall drive efficiency when using an ac synchro-nous motor is 920, whereas the equiva-

Load Sharing of Dual Motor Grinding Mill Drives | IEEE ...

Relatively small slowly varying shaft position and velocity variations superimposed on the normal running speed of dual drive grinding mill motors can cause individual motor torque variations which disturb load sharing. The magnitude of load or torque unbalance is a function of the magnitude of the mechanical variation, the type of motors used, i.e., induction or …

LSSM = Low Speed Synchronous Motor Drive Operation

low speed synchronous motor drive in 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.
