摘　　要：提出了一种新的建模方法,即在双凸极永磁电机电磁场有限元计算的基础上,利用非线性等效磁网络对双凸极永磁电机进行非线性建模与仿真。最后,用提出的非线性建模和仿真的计算方法,对一台三相12/8极双凸极永磁电机的相绕组电感和动态转矩进行了仿真。结果表明:相绕组电感和动态转矩的仿真与实验结果一致性较好。A new nonlinear modeling method is presented based on the FEM analysis. By using the nonlinear magnetic equivalent circuit model the doubly salient permanent magnet motor is nonlinearly modeled and simulated. Finally, using the proposed modeling method, a 12/8-pole doubly salient permanent magnet motor is simulated and the phase winding inductance is given. Also, the transient torque are concluded, simulation results are consistent with experimental data.
