Abstract

A new high performance brushless permanent magnet (PM) motor operating both as a synchronous and DC shunt motor has been presented. The motor has been designed using a classical approach with synchronous reactances obtained from the finite element method (FEM). For the load angle close to 90°, the motor can be switched automatically from AC to DC mode. The complete integrated drive system consists of two parts: (1) a motor with position sensors; and (2) IGBT inverter together with control circuitry. The mode switching control strategy, operation, and performance have been discussed
