Abstract

Different models for Switched Reluctance Machines (SRMs) are presented. All models are developed for the newest version (6.3) of PSpice for Windows. The models demonstrate the software's capabilities to define custom symbols and construct multilevel hierarchical models. PSpice also has strong analog behavioral modeling capabilities that are fully exploited. For this paper, 6-4 motors are simulated, but the models can be extended to other designs. The first model is based on an equivalent circuit representation with linear, voltage controlled inductors. The second model is based on a set of analytical equations which include saturation effects. In both cases, the electrical and mechanical system is modeled. Coupling between the windings is neglected. The models yield information about electrical as well as mechanical parameters such as induced phase voltage and torque. Both models produce comparable results in the unsaturated regime for the phase current. At higher current levels the model based on the analytical equations gives more accurate results.
