Prediction of the instantaneous and steady state torque of the switched reluctance motor using the finite element method (FEM)

Abstract

The locked rotor torque and instantaneous current and torque waveforms for a switched-reluctance motor (SRM) have been calculated using a two-dimensional finite-element method. The effects of switching the stator winding excitation on and off at different positions of the rotor are included. Experimental results for a 10-hp Oulton switched-reluctance motor are shown. In addition, the authors compare the SRM with a Century electric induction motor of the same rating.<>
