所提出的磁阻电机有一个转子，转子由磁通屏障型铁芯组成，铁芯带有狭缝以隔离磁通。铁芯采用压力机加工，便于批量生产和组装。定子的结构与感应电动机的结构相同。电机具有良好的可控性和非常小的转矩脉动。我们制作了一台实验电机，并对其性能进行了评价。结果表明，该电机的连续转矩是采用铁氧体磁铁的传统同步电机的1.7倍，在额定转矩下，峰值转矩波动为标称转矩的3%，速度响应为200Hz。本文首先对电机的结构进行了讨论。其次，给出了磁链分布和转矩的分析结果。最后，对实验电机的特性进行了讨论。
The proposed reluctance motor has a rotor which consists of flux barrier type iron cores with slits to isolate magnetic flux. The iron cores are processed with press machines, and are easy for mass-production and assembly. The stator has the same structure as that of an induction motor. The motor has excellent controllability and very small torque ripple.We have made up an experimental motor and have evaluated the performances. As the results, the motor has been shown to have 1.7 times continuous torque as large as that of the conventional synchronous motor with ferrite magnet, peak to peak torque ripple of 3% of a nominal torque at rated torque, and speed response of 200Hz.In this paper, firstly, the structure of the motor is discussed. Secondly, analytical results of flux distribution and resulting torque are shown. Finally, the characteristics of the experimental motor are discussed.
