PURPOSE:To make a commutator to unnecessary for the DC motor by a method wherein field windings are arranged in the axial direction, while the winding direction of rotor windings to a rotor is reversely arranged along the axial direction. CONSTITUTION:Positive and negative poles 13, 14 are provided to the yoke 12 of a DC mortor 11 in parallel with the axial direction of the rotation thereof, and the field windings 15, 16 are arranged to the poles 13, 14 thereof. While the rotor 17 is arranged rotation freely at the center of the field circuit of the DC motor 11. The rotor windings 21 are wound as to be buried in slots to a rotor core 19 provided at the central axis of the rotor 17 thereof. At this case, the rotor windings 21 are wound as to make the winding direction thereof to be reversed on the positive pole 13 side and on the negative pole 14 side. Accordingly driving force of the same can be obtained on the positive pole side and on the negative pole side in relation to the rotor, and the commutator is made to unnecessary for the DC motor. |
