Modeling and Analyzing of Surface-Mounted Permanent-Magnet Synchronous Machines With Optimized Magnetic Pole Shape

Abstract

Two types of eccentric magnetic pole shapes for optimizing conventional surface-mounted permanent-magnet (PM) synchronous machines with radial magnetization are presented in this paper. An analytical method based on an exact subdomain model and discrete idea is proposed for obtaining the air-gap flux density distribution in the improved motor. Cogging… (More)
