近年来，同步永磁（PM）电机获得了广泛的关注。这是由于它们的几个优点，包括高功率密度，高效率和高可靠性。关于PM机器的关键问题之一，特别是在安全关键应用中（例如多电飞机），一直是容错问题，因为机器不能被去激励。在机器侧以及功率转换器侧（包括功率转换器配置和补救控制策略）上已经做了大量工作。这项研究将提供一个彻底的审查和总结，什么已经涵盖在文献中的最新。这项研究将突出权衡（包括重量，成本和可靠性）所涉及的各种建议的方法和策略，更侧重于机器方面。在这项研究中讨论的方法包括主动控制方法从转换器侧，记忆电机，双凸极和磁通开关机，使用辅助绕组，机械弱磁方法，使用分流器和屏蔽，热保护和横向磁通机。该研究还将包括一些关于这一领域的研究在未来走向的评论。
Synchronous permanent magnet (PM) machines have been gaining a lot of interest over the years. This is due to their several advantages including high power density, high efficiency and high reliability. One of the key concerns about PM machines especially in safety-critical applications (such as the more-electric aircraft) has been the issue of fault-tolerance since the machine cannot be de-excited. A lot of work has been done both on the machine side as well as the power converter side (including power converter configuration and remedial control strategies). This study will provide a thorough review and summary of what has been covered in literature up-to-date. The study will highlight the tradeoffs (including weight, cost and reliability) involved in the various proposed methods and strategies with more emphasis on the machine side. The methods discussed in this study include active control methods form converter side, memory motors, doubly-salient and flux-switching machines, use of auxiliary windings, mechanical flux-weakening methods, use of shunts and shields, thermal protection and transverse flux machines. The study will also include some comments about where the research in this area is heading in the future.
