This paper presents a Spice-based flux-linkage model for the switched-reluctance motor (SRM). At present, most of the conventional methods require numerous data points of flux-linkage corresponding to rotor position and phase current to build a model, but this is time-ineffective. In the proposed method, the flux linkage is represented by a limited number of Fourier series terms. The coefficients of the Fourier series are determined by using the Froelich function. The proposed method allows the model to be built with a minimal number of static-characteristic data points, which are simply obtained through finite-element analysis (FEA); this allows for easy implementation and high computational efficiency. With the proposed Spice-based model, the converters of SRM drive system can be designed on the platform of Spice. The proposed model is validated with the experimental results.
