Abstract

Aiming at the problems of the low output torque and low overload capacity of induction motors caused by the decrease in the main flux at high speeds, the infl uence of split-winding on motor performance is studied in this paper, and the performance of the motor is optimized by a study of the winding split turns and winding split segments. First, the influences of winding turns and frequency on motor performance parameters are analyzed by an analytical algorithm, and the mechanism of split-winding on motor performance is revealed. Second, the performance of the motor before and after winding splitting is calculated by the finite element method, and the influences of winding splitting on the output torque and overload capacity are clarified. Through the study of the winding split turns and the number of winding split segments, the best speed at the winding split and the optimum number of winding split segments are determined, which provides a basis for the winding split principle when an induction motor is designed with split-winding. Finally, the performance of a prototype before and after a winding split is tested and the accuracy of the finite element calculation is verified.
