Abstract
The purpose of the present invention is to provide: a stator for a dynamo-electric machine, with which axial size can be reduced; and, an electrically powered wheel provided with the stator for the dynamo-electric machine. A statorfor a dynamo-electric machine is provided with a stator core, a plurality of coilsA-D, and jumper wiresA-C. The stator corehas first teetharound which a coil is wound and second teetharound which a coil is not wound. The first teethand the second teethare disposed alternatingly in the circumferential direction. The jumper wireextends circumferentially and radially with a bent section to absorb variations in the spacing between one coil and another, and is disposed at a position overlapping the second teethwhen viewed from the axial direction of the dynamo-electric machine. Further, the jumper wireis disposed closer to the stator corerelative to an axial end of a coil at least partially wound around the first teeth
