In this paper maximum average torque operation and minimum pulsating
torque operation of single phase induction motors are analyzed. An optimal method is then proposed to achieve a desirable motor performance including both a high average torque and a law pulsating torque over the entire motor speed range. A single adjustable capacitor and a switching power electronic device are used to indicabe the optimum value of the capacitor at every speed. Extensive simulation results show
the superior performance of the motor
under the proposed method over the maximum average torque, minimum pulsating torque And two-capacitor methods.
