Abstract

This paper discusses about the relative analysis of permanent magnet motors and switched reluctance motors (SRM) capability of electric vehicles (EVs) and hybrid electric vehicles (HEVs) system. Nowadays the pollution of the environment is increasing due to conventional vehicles. Hence, to reduce the pollution electric motors are very beneficial. Presently use of high power density magnetic motors like, brushless DC (BLDC) motors and permanent magnet synchronous motors (PMSM) have been the primary choice in the EVs and HEVs. But these motors have problems with demagnetization, high cost and fault tolerance. Therefore, in future permanent magnet motors will be replaced with SRM for EVs and HEVs. Because of SRM have no permanent magnets on the rotor, higher torque to power ratio, low losses and low acoustic noise compare to BLDC motors and PMSM. This paper is based on the properties of the special electric motors for example performance analysis, power density control, torque ripple control, vibration control, noise and efficiency. In this paper, special aspects of the BLDC motors, PMSM and SRM based drive systems for the EVs and HEVs are offered and reviewed. Also explained why permanent magnet motors are replaced with SRM for applications in EVs and HEVs.
