Abstract:
A self-excited reluctance motor comprising:a stator having a plurality of stator poles respectively wound by wires of different phases; a rotator having a plurality of rotator poles formed on an outer circumference thereof, the rotator rotatably inserted in the stator; and a commutator having a commutator body coaxially arranged with the rotator, and formed of an insulating material; an electrode formed on an outer circumference of the commutator body; a plurality of switching portions formed on the outer circumference of the commutator body at a predetermined distance from each other, and electrically connected with the electrode; a plurality of switching brushes electrically connected to stator wires of different phases and to the plurality of switching portions, for permitting an electric current to flow the respective stator wires; and an electrode brush connected to an external power source and to the electrode.
