This paper presents a static and dynamic analysis of non-linear magnetic characteristics in switched reluctance motor (SRM) based on finite element method (FEM). Static performances of the SRM are determined by using two-dimensional FEM under different rotor positions due to variations of the excitation current. Dynamic performances are obtained by the use of circuit-coupled time stepping finite element method. The proposed modeling strategy allows predicting the four-phase 8/6 SRM performances behaviors in both static and dynamic cases. Static torque values and current waveform give dynamic torque profile by using look up table in Simulink software. The advantage of the proposed approach is that it allows minimizing the torque ripples when changing the phase turn-on (θ_on) and the phase turn-off (θ_off) angles.
