pole induction machine is used to turn the mill. The motors are generally forced cooled; this allows running the motor at very low speed (approx. 510% of nominal speed) for service mode. Automatic positioning for liner changes and creeping for visual inspection can be performed with the main drive without the need of additional equipment.
