Abstract

This paper presents the method to determine the optimum values of the capacitance and rotor-slot skew pitch to maximize the efficiency of a single-phase capacitor-run permanent-magnet motor using the time-stepping finite element analysis and response surface methodology. The optimum values of the capacitance and rotor skew pitch to maximize the efficiency at the rated voltage and output are obtained. It has been investigated that the distance between permanent magnets and rotor slots has the important effects on the efficiency and starting performance.
