Dec 19, 2014· Advantages of SER drives for SAG mills. For large mills requiring variable speed, thewound rotor motor and SER drive are economical for a total rating of approximately 2MW to 16MW. Above 16MW, the gearless drive (cyclo-converter) is typically used because gearboxes and pinion gears reach their present limit in size.
