ELECTRIC MOTOR, POWER GENERATOR, AND VEHICLE DEVICE EQUIPPED WITH SAME

WIPO Patent Application WO/2020/179639

A1

Provided is an electric motor which can be assembled with respect to a structure in which a stator cannot be inserted from the axial direction and the output of which can be improved, and also provided are a vehicle power device equipped with this electric motor, a power generator, and a power generator-embedded wheel bearing equipped with this power generator. This electric motor (3) is an outer rotor type provided with: a stator having a stator core (18a) and stator coils; and a rotor facing the stator from the outside in the radial direction. The stator core (18a) is provided with: an annular portion; and a plurality of teeth (Ts) projecting outward in the radial direction from the annular portion, having the stator coils wound therearound, and lying in the circumferential direction. The stator core (18a) comprises a plurality of stator core divided bodies (Dv) divided in the circumferential direction at the annular portion and having the respective teeth (Ts). Divided both side portions of these stator core divided bodies (Dv), which lie in the circumferential direction, are provided with fitting portions (Kb) that are inserted and fitted into each other in the radial direction.
