摘　　要：表贴式永磁游标电机内部电磁参数复杂多变,MATLAB/Simulink不能精确反映不同运行工况下电机的实际电磁性能。将交叉耦合理论应用于表贴式永磁游标电机的磁链、电感和转矩模型的研究中,分析计算了交叉耦合对表贴式永磁游标电机磁链、电感和转矩的影响。基于ANSYS Maxwell、Simplorer及MATLAB/Simulink软件建立了场路联合仿真的电机驱动控制系统模型,测试了电机的驱动性能,并与MATLAB/Simulink定参数仿真结果进行了对比。理论分析和仿真结果表明,因电机内部电磁状态的实时变化,采用联合仿真分析方法的计算结果具有更高的准确性。The internal electromagnetic parameters of a surface-mounted permanent magnet vernier machine are complex and changeable,and MATLAB/Simulink cannot accurately reflect the actual electromagnetic performance of the machine under different operating conditions.The influence of cross coupling on the flux,inductance and torque of surface-mounted permanent magnet vernier machine is analyzed and calculated by applying the cross coupling theory to the model of flux,inductance and torque of surface-mounted permanent magnet vernier machine.The field-curcuit co-simulation model of a machine drive control system model was established based on ANSYS Maxwell,Simplorer and MATLAB/Simulink software.The driving performance of the machine is tested and compared with the simulation results of MATLAB/Simulink constant parameter simulation.The theoretical analysis and simulation results show that the calculation results of the co-simulation analysis method have higher accuracy because of the real-time change of the electromagnetic state inside the machine.
