Hello,<\/p>\n

I have an anlytical Model of a specific motor, based on saturated Magnet Equivalent Circuit(MEC). This analytical Model computes the Ld, Lq values. I need to validate this model by comparing the values obtained by FEM(Ansys Maxwell).<\/p>\n

I am wokring with transient solution of Maxwell 2D to compute dq inductance. As show in the below figure I found the values of Ld, Lq. The problem is I am getting values from ansys maxwell different form analytically computed one. May be because FEM is a non linear solution(with BH curve). I cannot do a linear solution in maxwell, because if I do so I have very high flux density near the bridges of rotor in my motor.<\/p>\n

How can I compute dq axis inductance from Ansys Maxwell which could be nearly equal to values obtained by analytical model. <\/p>\n

Any suggestion from your side will be helpful. Thanks.<\/p>\n
