Compared to the conventional SRM, fully-pitched winding reluctance motors have a higher salient ratio for a given motor dimensions. In addition, since the generated torque of the motor is determined by a product of the rate of change of mutual inductance with respect to a rotor position and winding current amplitude of the corresponding two phases, the motor is suitable for the bipolar current drives. Accordingly, the conventional general purpose inverter drive of the fully-pitched winding reluctance motor is possible. In this case, the optimum lead angles of voltage plays an important role to obtain the maximum torque and maximum torque/current ratio operations.In this paper, the scheme for determining the optimum angles of voltage without any measurement, and, the method to evaluate the drive characteristics in the design stage are proposed by a combination of simple magnetic and electrical analysis. The effectiveness of the proposed analytical scheme is verified by a experiment using a 400W prototype fully-pitched winding reluctance motor.
