Development of switched reluctance motors have revolutionized the industrial drives, aircraftapplications, food processors, fans, pumps, vacuum cleaners and many applications because of its simpler design, ruggedness and efficiency. Researchers are highly motivated to declare switched reluctance motor as a substitute of induction motors. This paper deals with a three-dimensional (3D) finite element analysis of a switched reluctance motor. The performance of the motor was analyzed by injecting voltage in the windings of the motor and transient analysis of the model was carried out. Flux densitydistributions, magnetic field intensity within the motor, the winding currents, flux linkages, induced voltages, total energy and energy error were obtained. It was observed that the winding currents were high because of the high value of the applied excitation voltage (120V). The plot of energy error showed that there was less than 1% error in the simulation which shows that the simulation was accurate.
