| Zusammenfassung: | To provide a cooling structure of a rotary electric machine improving cooling performance of a stator.SOLUTION: A motor 100 has a stator 6 having a plurality of tooth parts 7 and a coil 9 wound around the tooth parts 7. The coil 9 has a slot 8 formed between the tooth parts 7. The coil 9 has a first resin composition provided in the slot 8, filled in the slot 8 as a cooling structure, and covering the coil 9, and has a coil inside cooling passage 10 provided in a region where the first resin composition is filled, and extending in a rotation axis direction where coolant circulates inside.SELECTED DRAWING: Figure 1
【課題】ステータの冷却性能を向上させる回転電機の冷却構造を提供する。【解決手段】モータ１００は、複数のティース部７を有するステータ６と、ティース部７に巻かれたコイル９と、を有し、コイル９がティース部７の間に形成されたスロット８とを有し、コイル９がスロット８に設けられており、冷却構造として、スロット８に充填されコイル９を覆う第１の樹脂組成物と、前記第１の樹脂組成物が充填されている領域に設けられ内部を冷却剤が循環する回転軸方向に延出するコイル内側冷却用流路１０と、を有する。【選択図】図１ |
