Abstract

The paper presents some aspects of soft magnetic composite (SMC) material application in electrical machines. The stator core of the analyzed permanent magnet synchronous motor (PMSM) is made of magnetic iron sheets. Three types PMSM stators are analyzed: laminated with open slots, laminated with closed slots using SMC, and SMC stators. The comparative analysis is based on the magnetic properties and the calculated parameters of each motor model. The studied electromagnetic and electromechanical parameters are flux densities in various sections of the magnetic circuit and electromagnetic torque. The parameters´ values for the three types of stators are calculated using the finite element method (FEM).
