A brushless a.c. synchronous motor comprises a stator assembly having a stator winding which is supplied with power by an invertor. The main input power to the invertor flows through the primary winding of a transformer the secondary winding of which supplies current by way of a rectifier, to a field winding of the rotor assembly of the motor.
