Abstract

In this paper a new analytical model for the non-linear flux-linkage/current characteristics of the switched reluctance motors at different rotor positions is proposed. The model has been successfully verified by the simulation and the experimental results of the instantaneous current waveforms and the average torque values in both single pulse and multiple pulse operation of the motor. The uniqueness of the model lies in its defining a simple algorithm for determining the rotor position ($\theta$). Hence, sensorless operation of the motor can be easily implemented with the aid of this model.
