To provide an electric motor and a power apparatus for a vehicle with the electric motor, a power generator, and a bearing for a wheel with the power generator comprising the power generator which can use a stator coil with thick cross-sectional area while increasing facing area between a magnet of a rotor and a stator, satisfy restrictions of radial dimensions and axial dimensions, and improve output.SOLUTION: An electric motor 1 is an outer rotor type. In a stator core 4, an annular part 7 and a plurality of teeth 8 are divided, each tooth 8 has circumferential direction width of a tip part wider than circumferential direction width of a tooth main part, and a plurality of fitting grooves with cross-sectional shapes having narrowing parts on an opening side and extending along an axial direction are formed in a circumferential direction on an outer peripheral surface of the annular part 7. Each tooth 8 is provided with fitting parts 8c having cross-sectional shapes fitted into the fitting grooves, and inserted into each fitting groove of the annular part 7 in the axial direction to attachably/detachably fit into the annular part 7 in a radial direction on its base end part. Each fitting part 8c has the maximum width in the circumferential direction narrower than the circumferential direction width of the tooth main part.SELECTED DRAWING: Figure 1

    【課題】ロータの磁石とステータとの対向面積を増やしつつ太い断面積のステータコイルを用いることができ、径方向寸法および軸方向寸法の制約を満たすと共に、出力向上を図ることができる電動機およびこの電動機を備えた車両用動力装置、発電機およびこの発電機を備えた発電機付車輪用軸受を提供する。【解決手段】電動機1はアウターロータ型である。ステータコア4は円環部7と複数のティース8とが分割され、各ティース8は先端部分の円周方向幅がティース主部の円周方向幅よりも幅広で、円環部7の外周面に開口側に狭まり部を有する断面形状で軸方向に沿って延びる嵌合溝が円周方向に複数形成される。各ティース8は基端部分に、嵌合溝に嵌合する断面形状を有し円環部7の各嵌合溝に軸方向に挿入されて円環部7に対し径方向に離脱不能に嵌合する嵌合部8cが設けられる。各嵌合部8cは円周方向の最大幅がティース主部の円周方向幅よりも幅狭である。【選択図】図1
