本文提出了一种新型的开关磁阻电机，它的定子极尖之间的永磁体。与传统的SR电机相比，该电机具有较大的转矩和较高的效率。尽管存在永磁体，但既不产生感应电压，也不产生齿槽转矩。首先，永磁体的效果是由有限元法（FEM）解释。结果表明，所提出的SR电机的工作区域扩大的永磁体。接下来，所提出的电动机的可用性进行了实验澄清。与传统SR电机相比，最大转矩增加了约20%，并且在满负载条件下的效率显著提高。这意味着所提出的SR电机适合于驱动电动车辆（EV）和混合动力电动车辆（HEV），因为总是需要在满载或过载条件下的平稳加速。
This paper presents a novel switched reluctance (SR) motor which has permanent magnets between the stator pole-tips. The proposed SR motor has large torque and high efficiency in comparison with the conventional one. Neither induced voltage nor cogging torque is produced in spite of the existence of the permanent magnets. First, the effect of the permanent magnets is explained by finite element method (FEM). It is shown that the working area of the proposed SR motor is expanded by the permanent magnets. Next, the availability of the proposed motor is clarified experimentally. The maximum torque is increased by approximately 20% as compared with the conventional SR motor, and the efficiency under a full-load condition is improved remarkably. These mean that the proposed SR motor is suitable for driving an electric vehicle (EV) and hybrid electric vehicle (HEV) because a smooth acceleration under a full-load or overload conditions is always required.
