Advantages of SER drives for SAG mills | GoHz.com

Dec 19, 2014· 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 drive feeds power into the motor rotor allowing it to run faster than synchronous speed. So for a fixed torque and higher speed, the power obtained from the motor is higher than the motor nameplate rating.
