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.<br>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.
