混合励磁轴向磁场磁通切换电机(hybrid excited axial field flux-switching machine,HEAFFSM)结合了磁通切换电机和混合励磁同步电机的优点.为了研究HEAFFSM在低速区和高速区的运行性能,该文分析了 HEAFFSM 的结构特性、磁场调节机理及电感特性,并推导了它的数学模型.基于矢量控制方法,建立了HEAFFSM驱动系统.在低速区,提出了一种保持id= 0仅采用if进行增磁的控制策略,并采用该控制策略研究了HEAFFSM的低速区特性;在高速区,提出了一种基于电压差判断弱磁时刻的弱磁控制策略,并采用所提出的控制策略研究了HEAFFSM的弱磁特性.仿真与实验结果表明,在低速区,id=0控制可以充分利用HEAFFSM的输出转矩,HEAFFSM带载能力较强;在高速区,相对基于转速判断弱磁时刻的弱磁控制策略,该文所提出的弱磁策略可以充分利用逆变器的输出电压,拓宽HEAFFSM调速范围,因此HEAFFSM比较适合作为轮毂电机用作电动汽车的驱动.

The hybrid excited axial field flux-switching machine (HEAFFSM) combines the advantages of the flux-switching machine and the hybrid excited synchronous machine (HESM). In order to study the operating performances of HEAFFSM in low and high speed operation regions, the structure and the adjustment principle of magnetic fields of HEAFFSM are analyzed. The inductance and flux linkage characteristics are investigated. The mathematical model of HEAFFSM is deduced and the drive system is established according to the vector control method. Based on the stage control strategy, the loading capacity of HEAFFSM is researched by using theid =0 control in the low speed region. In the high speed region, a kind of flux-weakening control strategy is presented and the flux-weakening characteristics of HEAFFSM are studied, in which the moment of flux-weakening is judged based on the voltage difference. The simulations and experimental investigation are carried out, the results show that the torque of HEAFFSM could be fully utilized byid =0 control and HEAFFSM has a strong load capacity. Compared to the flux-weakening control strategy based on speed, the flux-weakening control strategy based on voltage difference to judge the moment of flux-weakening could take full advantage of the inverter output voltage and could broaden the range of speed regulation, so the HEAFFSM is suitable for in-wheel motors of electric vehicles (EVs).
