Abstract

This letter presents a simple model of nonlinear magnetization characteristics of a switched reluctance motor (SRM). The flux linkage is given as a continuous function of phase current and rotor position. This allows a mathematical formula to be found for the instantaneous torque. The model is valuable for computer-aided designs, especially for sizing and initial estimates where accuracy can be traded with time saving. The model was implemented to verify its degree of accuracy. The simulation program has the ability to calculate numerous parameters that can be very useful for quick estimates of the efficiency of a particular SRM drive or for motor selection
