### Ball Mill Drives - Mineral Processing & Metallurgy

Ball Mill Drives. One important advantage of the synchronous motor is the possible correcting of power factor within your operation, through its use. When using a synchronous motor we recommend having 200% starting torque, 120% to 130% pull-in torque, and 225% pull-out torque. These assume no greater than a 10% voltage drop at the motor terminals.
