为了研究轴向磁场磁通切换永磁（AFFSPM）电机在恒转矩和恒功率区域的运行性能，分析了AFFSPM电机的结构特征，推导了AFFSPM电机的数学模型。基于矢量控制建立了AFF-SPM电机的驱动系统。在恒转矩区域，采用了最大转矩电流比（MTPA）控制策略，并与id ＝0控制进行了对比；在恒功率区域，采用了一种基于电感补偿且保持q轴反电势不变的弱磁控制策略，并与普通弱磁控制进行了对比。仿真与实验结果表明，MTPA控制可以减小AFFSPM电机的铜耗。基于电感补偿的弱磁控制可以拓宽AFFSPM电机的恒功率运行范围，提高了AFFSPM电机运行性能，且AFFSPM电机轴向长度短、转子结构简单，因此比较适合用作电动汽车轮毂电机。

In order to study operating performance of axial field flux-switching permanent magnet (AFFSPM)machine in constant torque and constant power region,the structure and characteristics of AFFSPM are analyzed.The mathematical model of AFFSPM machine is deduced and a drive system is established based on vector control.The maximum torque per ampere control (MTPA)is employed in constant torque region and compared with id =0 control.In constant power region,the inductance compensation with constant q-axis back-EMF (back electromotive force)flux-weakening control is employed and compared with general flux-weakening control.The simulations and experimental analy-ses are carried out.The results show that copper loss is decreased due to MTPA control and the con-stant power region is broadened due to the inductance compensation.The machine is very suitable for in-wheel motor of the electric vehicle because of its shorter length and simple rotor structure.
