Calculation of the Characteristics of an Outer-Rotor-Type Multipolar SR Motor for Application to Electric Vehicles

抄録

In this paper, we design and analyze an outer-rotor-type multipolar switched reluctance (SR) motor, and examine the possibility of realizing an electric vehicle (EV) with an SR motor inside each of its two rear wheels, that is, an EV with a gear-less and in-wheel layout. We used a method for calculating the operating characteristics proposedpreviously by authors for designing the SR motor, andevaluated the optimum exciting phase. Furthermore, we improved the proposed method so that the basiccharacteristics of the EV with SR motors can be calculated, and we investigated the initial and steady-state currents and the maximum speed of the vehicle.
