开关磁阻（SR）电机具有双凸极结构。与其他电机相比，它具有结构简单、坚固、成本低、能高速旋转等优点。然而，存在转矩涟漪和声噪声的问题。此外，功率重量比和效率也有待提高。电力电子技术的最新进展允许细致的电流控制，以减少涟漪和噪声。另一方面，必须进一步检查芯材料和电机结构，以提高功率重量比和效率。提出了一种新型的定子极间永磁SR电机。建议的电机的特性计算通过使用有限元法（FEM），并与传统的SR电机。建议SR电机的可用性，然后澄清实验。
A switched reluctance (SR) motor has a doubly salient pole structure. It has some merits in comparison with other motors: simple structure, robustness, low cost, and capability for high-speed rotation. However, there are problems of torque ripple and acoustic noise. In addition, the power-to-weight ratio and efficiency need to be improved. Recent advances in power electronics technology allow meticulous current control to reduce the ripple and noise. On the other hand, the core material and motor structure must be further examined to improve the power-to-weight ratio and efficiency. This paper presents a novel SR motor with permanent magnets between the stator poles. The characteristics of the proposed motor are calculated by using a finite element method (FEM) and compared with those of conventional SR motors. The availability of the proposed SR motor is then clarified experimentally.
