ABSTRACT:
A switched reluctance motor comprising a stator including a plurality of phase coils, a rotor rotatably mounted coaxially with the stator, a first commutator plate comprising a plurality of first contact plates wherein each phase coil of the plurality of phase coils is electrically coupled to a member of the plurality of first contact plates, a first switching device, a first rotatably mounted brush consecutively providing electrical contact between each first contact plate and the first switching device, a second switching device, a second commutator plate comprising a plurality of second contact plates wherein each phase coil of the plurality of phase coils is electrically coupled to a member of the plurality of second contact plates, a second rotatably mounted brush consecutively providing electrical contact between each second contact plate and the second switching device, wherein, when the first switching device is closed and the second switching device is open, the rotor rotates in a first direction and wherein, when the second switching device is closed and the first switching device is open, the rotor rotates in a second direction opposite to the first direction.
