为研究双三相永磁同步电动机交互磁饱和机理,根据有限元法得到d,q轴电感与电流的非线性关系,搭建了基于内插外推法的电机饱和模型,仿真实验,验证了所建立的饱和模型的有效性.
For the study of the cross-coupling magnetic saturation of the dual three-phase permanent magnet synchronous motor(PMSM),according to the nonlinear relationship between the inductances and currents of the d and q axes obtained by the finite element method,a saturated motor model based on the interpolation and extrapolation was built by using the MATLAB/Simulink.To verify the validity of the saturated model,several simulation experiments was conducted.
