A new high performance brushless permanent magnet (PM) motor operating both as a synchronous and d.c. 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{degree} the motor can be switched automatically from a.c. to d.c. mode. The complete integrated drive system consists of two parts: (1) motor with position sensors and (2) IGBT inverter together with control circuitry. The mode switching control strategy, operation, and performance have been discussed.
