ABSTRACT:
A method for controlling the output torque condition of an induction motor includes the steps of generating a slip frequency in the motor proportional to the desired output torque condition while simultaneously establishing the magnitude and phase displacement of the stator current at preselected values. The invention also obtains the speed control of self excited alternating current motors.
