| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a rotary electric machine capable of improving a space factor of a tortoiseshell-shaped coil in a slot.SOLUTION: The rotary electric machine includes a stator 2 in which a stator winding 23 is inserted in a slot 22 of a stator core 21. The stator winding 23 is a tortoiseshell-shaped coil wound with coil strand by a plurality of turns. The tortoiseshell-shaped coil includes a pair of straight parts 231 inserted into the slot 22 and a pair of coil end parts 232 connected with the pair of straight parts 231. The tortoiseshell-shaped coil includes a plurality of layers divided in the peripheral direction.SELECTED DRAWING: Figure 3
【課題】スロットにおける亀甲形コイルの占積率を向上させることができる回転電機を得る。【解決手段】固定子鉄心２１のスロット２２に固定子巻線２３が挿入された固定子２を有する回転電機であって、固定子巻線２３は、コイル素線が複数回巻き回された亀甲形コイルであり、亀甲形コイルは、スロット２２に挿入される一対の直線部２３１と、一対の直線部２３１を繋ぐ一対のコイルエンド部２３２とを有し、亀甲形コイルは、周方向に分割された複数の層を有している。【選択図】図３ |
