Abstract
A device for high efficiency motor control includes an induction motor and a controller. The induction motor generates a motor torque and has a given rotor resistance and magnetizing inductance at a specific temperature. The controller is coupled to and controls the induction motor. The controller includes control logic operative to maximize the motor torque using a flux current and a torque current. The controller determines the flux current and torque current based upon a requested torque, a requested speed, the magnetizing inductance, the temperature and the rotor resistance.
