分数槽集中绕组（FSCW）同步永磁（PM）电机近年来受到广泛关注。这主要是由于这种类型的绕组提供了几个优点。这些优点包括高功率密度、高效率、短端匝数、高槽填充系数（特别是与分段定子结构相结合时）、低齿槽转矩、弱磁能力和容错性。本文将从机遇和挑战的角度对FSCW同步永磁电机进行全面分析。本文将涵盖FSCW同步永磁电机的理论和设计，实现高功率密度，磁通减弱能力，单层与双层绕组的比较，容错转子损耗，寄生效应，内部与表面永磁电机的比较，以及各种类型的电机。本文还将简要介绍FSCW同步永磁电机的商业应用。
Fractional-slot concentrated-winding (FSCW) synchronous permanent magnet (PM) machines have been gaining interest over the last few years. This is mainly due to the several advantages that this type of windings provides. These include high-power density, high efficiency, short end turns, high slot fill factor particularly when coupled with segmented stator structures, low cogging torque, flux-weakening capability, and fault tolerance. This paper is going to provide a thorough analysis of FSCW synchronous PM machines in terms of opportunities and challenges. This paper will cover the theory and design of FSCW synchronous PMmachines, achieving high-power density, flux-weakening capability, comparison of single-versus double-layer windings, fault-tolerance rotor losses, parasitic effects, comparison of interior versus surface PM machines, and various types of machines. This paper will also provide a summary of the commercial applications that involve FSCW synchronous PM machines.
