Advantages of SER drives for SAG mills | GoHzDec 19, 2014 . The SER drive via a feedback transformer feeds energy back into the power supply. This returned energy is proportional to the speed difference from synchronous speed. So at say 85% speed, 15% of the motor rated power is returned from the rotor to the supply. At a hyper-synchronous speed, the SER.synchronous motor for mill drive advantages,Advantages of low speed drive solutions - PACEDec 10, 2012 . As a result, installation of variable speed motors tends to be easier. Low speed synchronous motors with frequency converter control can generate sufficient torque to start a mill turning without needing an air clutch. This is a major advantage of variable over fixed speed drives, because eliminating the clutch.
