The gearless drive synchronous motor accelerates the mill from standstill up to operating speed. Within the range of 80 100 0/o of the nominal speed, the best power factor can be obtained. The mill can for a limited time be operated at very low speeds for positioning the manholes of the mill shell; and no extra equipment is needed.

// Breakdown Torque (BDT) The highest percentage of rated full load torque the motor generates prior to reaching full load speed. Motors that do not have sufficient starting torque for the driven equipment will stall during starting. A stall condition requires the mine operator to lower the starting load before attempting to restart the equipment.
