磁通反转永磁电机（FRPMMs）具有转子结构简单、转矩密度高、瞬态响应快等优点。然而，FRPMMs的一般设计方法尚未建立。因此，本文主要侧重于开发三相FRPMMs的设计方法。首先，基于磁动势-磁导率模型，分析推导了施胶方程。然后分析了尺寸方程中槽极组合、气隙半径、电载荷和等效磁载荷等关键参数对转矩密度的影响。总结了可行的槽极组合，并推荐了相应的绕组形式，以最大限度地提高输出转矩。此外，还对定子和转子进行了详细的几何设计。最后，通过12槽/17极FRPMM样机的二维有限元分析和实验验证了所提出的设计方法。
Flux reversal permanent magnet machines (FRPMMs) exhibit many advantages such as simple rotor configuration, high torque density, fast transient response, etc. However, the general design procedure of FRPMMs has not been established. Thus, this paper mainly focuses on developing a design methodology of three-phase FRPMMs. First, the sizing equations are analytical derived based on a magneto motive force (MMF)-permeance model. Then, the influences of several key parameters in the sizing equation including slot-pole combination, airgap radius, electric loading and equivalent magnetic loading on the torque density are analyzed. Moreover, the feasible slot-pole combinations are summarized and the corresponding winding types are recommended in order to maximize the output torque. Besides, the detailed geometric design of stator and rotor are presented. Finally, the proposed design method is verified by 2D finite element analysis (FEA) and experiments on a 12-slot/17-pole FRPMM prototype.
