Due to the significant advantages of cost savings, low temperature rises and high efficiency, synchronous reluctance machines (SynRMs) have attracted growing interest from academia to industrial applications. Numerous articles have been published to obtain a SynRM with improved performance (i.e., a high torque density and efficiency and a lower torque ripple) using different focusing points at healthy and faulty conditions such as rotor design, magnetic steel grade, stator winding, and fault tolerance control (FTC) strategy. Hence, this article reviews the scientific researches about SynRMs aiming to improve their performance. These scientific researches can be categorized into four sections: 1) optimal rotor design; 2) magnetic steel grade; 3) winding configurations; and 4) FTC strategies.

同步磁阻电机的性能改进——综述研究

由于节省成本、低温升和高效率的显着优势，同步磁阻电机 (SynRM) 已吸引了从学术界到工业应用的越来越多的兴趣。已经发表了许多文章，以在转子设计、磁钢等级、定子绕组和故障等健康和故障条件下使用不同的焦点来获得具有改进性能（即高扭矩密度和效率以及更低的扭矩纹波）的 SynRM容差控制 (FTC) 策略。因此，本文回顾了旨在提高 SynRM 性能的科学研究。这些科学研究可以分为四个部分：1）优化转子设计；2）磁钢牌号；3) 绕组配置；4) FTC 策略。
