Abstract: A magnetic geared motor includes a stator including a plurality of teeth that produce a magnetomotive force, a first rotor that rotates by the magnetomotive force of the stator, and a second rotor that, in response to rotation of the first rotor, rotates at a lower speed than the first rotor. The first rotor, the second rotor, and the stator are disposed coaxial to each other, and a plurality of magnets of different polarities are disposed in respective slot openings present between each two adjacent teeth.
