摘要
A compact three-phase permanent magnet rotary machine having minimal reluctance torque and electromagnetic torque ripple, and maximum energy efficiency and starting torque per unit volume of winding, comprises an armature having 3(2n+1) ferromagnetic poles and slots, where n is an integer of 1 or more, and a permanent magnet assembly having either 2, 4 or 6 permanent magnet poles. Each of the three phases of the winding comprises multiple coils, each wound about a respective ferromagnetic pole and occupying a pair of slots located immediately on each side of a respective pole. The coils of a particular phase are located within a sector of the circular array of ferromagnetic poles encompassing 2n+1 poles.
