Abstract

The influence of various design parameters on the back electromotive force (back-EMF) and its total harmonic distortion (THD) in surface type permanent magnet synchronous machine (SPMSM) is investigated in this paper. The ratio of pole angle, slot opening, pole number and size of SPMSM are chosen as the design parameters. By using analytical method based on the space harmonic analysis, the variation of back-EMF and back-EMF THD are estimated and mapped according to the variety of these design parameters. And parameter results will be selected by range for meeting the characteristic requirements of SPMSM. The study results of this paper will be helpful to the PMSM design with back-EMF and THD optimization. The results will be verified by the finite element analysis.
