In the past few decades, the stator permanent magnet (PM) machines have attracted much research attention because of their reliable rotor structure, high power density, wide speed range, and strong fault-tolerant ability. Among the recently proposed stator PM machine topologies, the stator slot-opening PM (SS-PM) machines are becoming increasingly popular because of their higher stator space utilization and robust rotor structure. According to the SS-PM magnetization direction, the SS-PM machines can be classified into three categories, namely, the tangentially magnetized stator slot-opening PM (TMSS-PM) machines, the radially magnetized stator slot-opening PM (RMSS-PM) machines, and the compound magnetized stator slot-opening PM (CMSS-PM) machines. The associated working principle and electromagnetic performance of different SS-PM machines can be diverse. Therefore, this article gives an overview of SS-PM machines in terms of machine design, working principle, and machine performance. A qualitative performance evaluation and comparative study of SS-PM machines are presented, and the future challenges and potential opportunities in the SS-PM machine design are discussed.

定子开槽永磁电机概述

在过去的几十年里,定子永磁(PM)电机以其转子结构可靠、功率密度高、调速范围广、容错能力强等特点而备受研究关注。在最近提出的定子永磁电机拓扑结构中,定子开槽永磁 (SS-PM) 电机因其更高的定子空间利用率和坚固的转子结构而变得越来越流行。根据SS-PM磁化方向,SS-PM电机可分为三类,即切向磁化定子开槽永磁(TMSS-PM)电机、径向磁化定子开槽永磁(RMSS-PM)电机) 机和复合磁化定子开槽永磁 (CMSS-PM) 机。不同SS-PM机器的相关工作原理和电磁性能可以是多种多样的。因此,本文从机器设计、工作原理和机器性能等方面对SS-PM机器进行了概述。提出了 SS-PM 机器的定性性能评估和比较研究,并讨论了 SS-PM 机器设计中的未来挑战和潜在机遇。
