The drive keeps the motor starting currents below full load amps at all times. Starting the motor across the line without the drive, the starting inrush current is six times full current. Using the drive, motor stress is significantly reduced and motor life is extended. All three grinding mills are driven by synchronous motors of identical ratings.
