Abstract
The switched reluctance motor (SRM) drives are emerging as an attractive solution for electric vehicle (EV) applications due to its favorable driving capacity. However, the inherent net radial force of SRM has an important effect on the vehicle ride comfort. This paper investigates the influences of net radial force induced by eccentric SRM with series/parallel circuits on vehicle ride comfort. The mechanical–electrical–magnetic coupling model of SRM is established by combing the numerical simulation and analytical method, in which the series and parallel circuits are structured, respectively. Then, quarter vibration vehicle models coupled with SRM are established. The net radial force of the two SRMs and ride comfort of the corresponding vehicles are simulated and discussed at different conditions. It is concluded that the SRM with parallel circuits generates smaller net radial forces, and the vehicle driven by SRM with parallel circuits will achieve better ride comfort due to the difference of branch currents.
