Core loss model based on finite-element method for switched reluctance motors

A core loss model for switched reluctance motor (SRM) is introduced in which flux waveforms in different parts of the motor are predicted by carrying out a two-dimensional (2D) finite-element (FE) transient analysis using ANSYS FE software. Since the predicted flux waveforms are non-sinusoidal, the improved Steinmetz equation is used for core loss calculation. The core loss model is developed totally in ANSYS parametric design language as a parametric model and it can be used easily for different types of SRM. The developed core loss model is applied to an 8/6 SRM and the experimental results are presented for validation of the model.
