· get an optimized design. The efficiency factor of such a mill drive is governed by winding (copper) losses. Due to the small stator frequencies the iron losses are low. The low speed of these mill drives leads also to negligible air friction losses of the rotating parts. Therefore the copper in sta-tor and rotor must be in creased to its maxi-mum.
