Core loss analysis for switched reluctance motor under hysterisis current control and single pulse modes

In this paper, a detailed core loss analysis for an 8/6 switched reluctance motor is conducted. A 2D Finite element model of the switched reluctance motor in Maxwell coupled with electrical circuit in ANSYS Simplorer is built for the core losses analysis. The flux density waveform and core loss associated with various stator and rotor areas are analyzed under hysteresis current control and single pulse mode operations. The turn-on and dwelling angle effects on the core loss are presented and discussed in these two operation conditions. In addition,harmonic analysis of flux density for various stator yoke areas are conducted to understand dewlling angle impact on core loss and optimal controlled parameters for minimum core loss is also discussed.
