Design and Analysis of Electric Motors with Soft Magnetic Composite Core

Abstract

This paper aims to present the design aspects of electrical motors with soft magnetic composite (SMC) core. Combined classical and modem analysis procedures are proposed for developing SMC motors. A permanent magnet claw pole motor using SMC material as the stator core was firstly designed by the equivalent magnetic circuit method. Three dimensional finite element magnetic field analysis was conducted to refine the design and calculate some key parameters. The design and analysis method was validated by the experimental results on the prototype.
