摘要：从转矩成分的角度对交流同步电机进行了分类，并针对转矩成分指出了各类电机的特点，从而引出同步磁阻电机的原理。进而比较了同步磁阻电机相比于异步电机、永磁同步电机和开关磁阻电机的优势与劣势，指出了同步磁阻电机替代上述电机的潜在可能和限制因素。综述了增大同步磁阻电机转矩密度、削弱转矩脉动、提高功率因数、减小铁耗和加强机械强度所采用的设计措施。最后根据同步磁阻电机的控制原理分析了其基本控制方式。
关键词：同步磁阻电机；转矩密度；转矩脉动；控制策略
Abstract: Synchronous AC machines were categorized from the perspective of torque components, and the features of each category of machine were described according to the torque components, thus, the principle of synchronous reluctance machine (SynRM) was presented. Besides, advantages and disadvantages of the SynRM were compared with the induction machine (IM), permanent magnet synchronous machine (PMSM), and switched reluctance machine (SRM). Accessibility and limitation of the SynRM to substitute the other machines were analyzed. Measures to achieve high torque density, low torque ripple, high power factor, low iron loss and high mechanical strength were summarized. Finally, basic control strategies of the SynRM were presented according to its operation theory.
Key words: synchronous reluctance machine; torque density; torque ripple; control strategy
