DESIGN COMPARISON OF SURFACE-MOUNTED PERMANENT MAGNET SYNCHRONOUS MOTORS WITH INNER AND OUTER ROTOR APPLICATION FOR ELECTRIC VEHICLE

Abstract

The surface-mounted permanent magnet synchronous motor (SPMSM) is one of the electric machines applied widely in the fields of electric vehicles (EVs) and electrical drives and electric drives in industry and civil. There are two types of SPMSM motors, namely inner rotor SPMSM and outer rotor SPMSM. To analyze and calculate the advantages and disadvantages, as well as compare the performance of these two types of motors. This SPMSM research problem presents an analytical model to preliminarily design the main parameters of SPMSM with both inner and outer rotor types. Then, the finite element method is used to simulate, analyze and compare the electromagnetic parameters of the motors. This research result is also the basis for calculation, analysis, design and control for industrial machines and especially for application in the field of electric vehicle motors
