摘　　要： 提出了一种新型结构的6/13极定子模块式轴向磁场磁通切换永磁(AFFSPM)电机。该电机具有结构紧凑、转矩密度大、效率高和容错性能强等特点。分析了AFFSPM电机结构和工作原理,推导了AFFSPM电机的数学模型。利用MATLAB/Simulink仿真软件搭建了AFFSPM电机控制系统仿真模型,分别对滑模速度控制和比例谐振控制的控制策略进行仿真研究,分析对比AFFSPM电机的转速、转矩和三相电流的波形。仿真结果表明,与比例谐振控制策略相比而言,滑模控制策略下该新型AFFSPM电机控制系统具有较好的静态和动态性能。 A novel 6/13-pole axial field flux-switching permanent magnet （AFFSPM） motor with stator modules motor was proposed, which had the advantages of compact structure, high torque density, high efficiency and strong fault tolerance. The structure and working principle of AFFSPM motor were analyzed, and the mathematical model of AFFSPM motor was derived. The simulation model of control system was built by using MATLAB/Simulink simulation software. The control strategy of sliding mode speed control and proportional resonant control were investigated, respectively. The waveforms of speed, torque and three-phase currents of AFFSPM motor were analyzed and compared. The simulation results showed that, the control system of the novel AFFSPM motor had better static and dynamic performance under the sliding mode speed control strategy compared to the proportional resonant control method.
