Abstract

This paper presents an outer rotor in-wheel switched reluctance motor, designed for a cart type electric vehicle. Both of the short and fully pitched winding configurations are developed and analyzed considering the requirements of such a vehicle propulsion motor. Torque profiles and ripple ratios, which are the most important parameters of in-wheel applications are compared for various loading conditions. It is observed that with fully pitched configuration, torque output is increased. However, increasing ripple ratio makes this winding configuration inconvenient for in-wheel propulsion applications, unless any ripple control algorithm is applied.
