gearless motor mounted directly onto the mill. In addition, a gearbox can be used to reduce the speed of a high speed motor. This gearbox is then placed between the high speed motor(s) and pinion(s) and the low speed shaft driving the ring gear. Thus, there is the decision between gearless drives and drives using a gear, and, if gear driven,
