开关磁阻电机（SRM）是混合动力汽车（HEV）用无稀土电机的候选对象之一。SRM已经开发出具有精确IPMSM尺寸的具有竞争力的最大扭矩、操作区域和最大效率的SRM。然而，在最大转速下，SRM的凸极导致约1.3 kW的考虑风损。此外，显著的声学噪声由凸极引起。本文提出了一种简单的圆柱形外形转子的设计，并与常规转子进行了比较。结果表明，由于减小了风阻损失，提高了效率。还发现声学噪声显著降低。
A Switched Reluctance Motor (SRM) is one of the candidates of rare-earth-free-motors for hybrid electric vehicle (HEV). An SRM has been developed with exact IPMSM dimensions with competitive maximum torque, operating area, and maximum efficiency. However, considered windage loss of around 1.3 kW is resulted by the salient poles of the SRM at the maximum rotational speed. In addition, considerable acoustic noise is caused by the salient poles. In this paper, a simple design of a cylindrical outer shape rotor is proposed and a comparison to the conventional rotor is carried out. It is found that the efficiency is improved thanks to the windage loss reduction. It is also found that the acoustic noise is significantly reduced.
