Abstract:
A motor is provided that is capable of electronically switching between operating in a high torque mode and a low torque mode. The high torque mode may be switched reluctance mode and the low torque mode may be synchronous reluctance mode. The motor has a stator having two sets of armature windings, and a rotor having two sets of flux barriers each adapted to shape a magnetic flux distribution generated by a corresponding one of the sets of armature windings. The stator may comprise a plurality of teeth circumferentially spaced apart from one another around a rotation axis of the motor. The armature windings may include switched reluctance armature windings, each wrapped around a single stator tooth, and synchronous reluctance windings, each wrapped around multiple adjacent stator teeth. An inverter and controller may be connected to each set of armature windings for controlling the electronic switching of the armature windings. The inverter and controller are operable to toggle the motor between the two modes of operation using pulse-width modulation-like techniques.
