In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is % of the total energy supplied to the mill setup.

The poles of the gearless or synchronous motor (also called wraparound motor or ring motor) are directly installed on the pole flange of the mill shell, turning the mill body into the rotor. The stator is then wrapped around the mill. The gearless motor is fed by a cycloconverter which has a rated output frequency of around 5 Hz for the GMD drive.

If your motor has an efficiency of and you measure 1000 kW at the motor input, then the motor output power you would measure (with a torque device) is 900 kW. This is why you are measuring more input power than the rated power; the rated "input" power would be 1500 HP divided by the motor efficiency.
