  • Publication number: 20130187488
    Abstract: In a rotating electrical machine of axial-gap type in which a stator and a rotor are opposed to each other in arrangement and winding axis is parallel with a rotating shaft direction, the stator has an “m” protruding in the rotating shaft direction are distributed along a circumferential direction thereof, in which the winding pole is formed of a magnetic member having a plurality of teeth in a circular-arc shape in a diameter direction, and wherein the rotor is formed of a magnetic member having a plurality of teeth in a circular-arc shape in a diameter direction, and the number of the teeth of the stator and the rotor are arranged in a manner opposite to each other through air gap so as to be engaged with each other. The stator and the rotor are opposed on both sides of the rotor and the stator.
