  • Load Sharing of Dual Motor Grinding Mill Drives - IEEE ...

    Abstract: 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 synchronous, the number of motor
