Abstract: Provided is a magnetic geared motor and a magnetic gear that support pole pieces with high rigidity, have small residual stress, and are very easy to assemble. Included are stator, first rotor that rotates by magnetic flux generated by stator, and second rotor that rotates at a speed different from that of first rotor. Second rotor includes a plurality of pole pieces annularly arranged along the circumferential direction of second rotor, and frame including a circumferential portion including a plurality of gaps respectively corresponding to the plurality of pole pieces and in each of which the corresponding one of the plurality of pole pieces is at least partly inserted. The plurality of pole pieces and frame are integrated with mold resin.

Abstract: A bus bar guide is provided to fix bus bars that connect a plurality of coils disposed in a motor. The bus bar includes a conductor that has a plate shape and has a first surface and a second surface continuous with the first surface. The bus bar guide is configured by annularly arranging a plurality of bus bar guide pieces each including an insulator. Each of the plurality of bus bar guide pieces is provided with a groove that holds the first surface of the bus bar and positions the bus bar.
