ABSTRACT


The low-cost magnet less switched reluctance motor (SRM) speed-torque characteristics are perfectly suited for electric vehicles (EVs) drive performances are better than polyphase machines. The main drawback of SRM for EVs is torque ripple, it can be mitigated by optimal design aspects. In this study, to design SRM by changing the position of the stator and rotor pole, an increasing number of poles are investigated with optimum geometry. This paper presents the design procedure for EV applications of 250 kg mass, developed power of 2.9 kW and acceleration of 30 kmph. SRM rotor modification with two different cases of design of SRM with exterior rotor case with three-phase stator configuration 8/6, 10/6 and design of SRM with an interior rotor with three and four phases stator configuration 6/4, 8/6. The simulation was carried out using an electromagnet infolytica simulation package. The conditions of flux linkages, static torque, and rotor configurations are obtained using finite elements. FEA is used to verify the design of the SRM from an electrical standpoint. The results and performance analysis of the SRM drive were compared and analyzed for both cases. It is observed during the static and transient analysis that, the torque ripple in the 8/6 interior rotor design is lesser than in the exterior rotor design. The Interior rotor configuration 8/6 model may best be suited for EV’s high-speed application due to its low torque ripple characteristics compared to other models.
