Nowadays flux switching machines (FSMs) offer important role in various high torque applications. In these machines, the flux sources such as field excitation coil (FEC), armature winding and permanent magnet (PM) are located in the stator while leaving the rotor part as winding less. However, FSMs with single stator associate with limited free space for active sources in stator, which leads to some drawbacks of complicated structure, less path for flux flow, flux cancellations, heat generation and demagnetizing effects. To overcome this issue, FSMs using double stator (DS) have been proposed by many researchers which provide more free space for active sources and flux to flow. Therefore, in this paper design and performance of DS FSMs with various excitation sources such as field excitation FE FSMs, PM FSMs and hybrid excitation HE FSMs are reviewed. All the highlighted insights and recommendations of this review will hopefully lead to increasing efforts towards the development of advanced DS FSMs for various applications.

如今，磁通开关机（FSM）在各种高扭矩应用中发挥着重要作用。在这些电机中，磁通量源（例如励磁线圈（FEC），电枢绕组和永磁体（PM））位于定子中，而转子部分的绕组较少。然而，具有单个定子的FSM与定子中有源源的有限自由空间相关联，这导致一些缺点，即结构复杂，通量路径较少，通量抵消，产生热量和消磁效果。为了克服这个问题，许多研究人员提出了使用双定子（DS）的FSM，它们为有源源和助焊剂提供了更多的自由空间。因此，在本文中，采用各种激励源（例如场激励FE FSM）的DS FSM的设计和性能，审查了永磁有限状态机和混合激励高频有限状态机。这次审查中所有突出的见解和建议都有望导致为开发适用于各种应用程序的高级DS FSM做出更多的努力。
