Abstract :
Low cost, high reliability, low weight and competitive efficiency combine to make the switched reluctance motor (SRM) drive a strong candidate for application in future electric vehicle (EV) propulsion systems. In this paper , a three-phase 6/4 structure switched reluctance motor used in small size EV is proposed. Start performance and output property are both improved through optimizing the stator structure. Static characteristic of the motor is analyzed and calculated by using the method of the finite element analysis. Flux linkage curves of SRM are obtained at different rotor position. Electromagnetic calculation is carried out. On the basis of this, the capabilities are compared before and after optimization. At last, the optimal design of the SRM is finished.
