Abstract :
A comparison of computed and measured performances of a 10 hp Oulton switched reluctance motor (SRM) and a comparison with the performance of induction motors are presented. The instantaneous current and torque waveforms are computed for the SRM using the results of finite element method (FEM) analysis. The SRM calculated and experimental locked rotor torque, instantaneous current, efficiency, and losses when pulsed voltage excitation is applied to the motor windings were compared. In all cases, there is quite good agreement between the theoretical and experimental results. In addition, the measured total losses, efficiency, and temperature rise for a 10 hp SRM and different induction motors of the same rating are presented. The SRM has a higher efficiency and a lower temperature rise than the induction motors tested
