Abstract: This paper presented a nonlinear magnetization data model of switched reluctance motor(SRM)using dynamic inductance and static inductance based on Matlab/Smulink.The dynamic inductance and static inductance of SRM were calculated with an enhanced incremental energy method after the 2D finite element analysis of magnetic field.Then the derivative of static inductance with rotor position angle was computed by cubic spline interpolating function.Finally established the nonlinear model of SRM was with the lookup table in Matlab/Simulink.The model avoided the differential computation,the simulation speed was improved obviously,and the induced electromotive force and motion electromotive force can be studied real-timely.
