Characteristic measurements of switched reluctance motor on prototype electric vehicle

Interior permanent magnet synchronous motor (IPMSM) is the most popular traction electric motors for hybrid electric vehicles (HEVs). In general, rare earth permanent magnets are used in the IPMSMs. However, the price of the rare earth materials has been rapidly rising in recent years. This is recognized as a serious problem for the automobile industry. A switched reluctance motor (SRM) is one of the possible solutions for the problem. In our previous paper, a prototype machine has been designed and experimented on a test bed. In this paper, the characteristics of vibration and acoustic noise are investigated on electric vehicle (EV) with a prototype SRM.
