Switched reluctance motors (SRM) have several desirable features, including simple construction, high reliability, and low cost. The operating characteristics of the SRM depend on the excitation conditions, such as the phase angle and pulse width of the excitation voltage applied to the motor winding. For the optimum design, it is necessary to clarify the quantitative relationships between the excitation conditions and the operating characteristics. We conducted experiments to determine the torque-speed characteristics and efficiency of the 8/6 four-phase SRM for various phase angle of the excitation voltage. Results showed that the trial SRM has an efficiency of more than 80% over a wide operating range.
