Abstract	A fast method to calculate the iron loss of switched reluctance motor (SRM) is proposed. The key of the method is that the flux density waveforms in different parts of the motor can be obtained quickly. First, the static flux density data varying with phase current and rotor position in various parts of SRM are obtained by finite element method (FEM). Then, the static flux density data are stored in 2D look-up tables in Matlab/Simulink to get the flux density waveforms by look-up table method, and the obtained flux density waveforms are verified by FEM results. Since the flux waveforms are non-sinusoidal and non-linear, an accurate and fast model for the iron loss prediction is presented, and different modified factors are applied to calculate the hysteresis loss according to the classification of flux density waveforms. Based on that, the calculation model is established in Matlab/Simulink, and iron losses of a three-phase 6/4 structure SRM under different turn-on and turn-off angles and load conditions are calculated and analysed. Finally, measured results are presented to verify the precision of the calculation model.
