Summary:To provide a rotary electric machine capable of improving the cooling performance thereof.SOLUTION: In a disclosed rotary electric machine, a stator winding is formed by combining multiple single-coil units each of which comprising a slot insertion part to be inserted into a slot of a stator core and a coil end that electrically connects each of the slot insertion parts. A concavity is formed in the conductors on the top of the coil end.SELECTED DRAWING: Figure 3 【課題】回転電機の冷却性能を向上させることを目的とする。【解決手段】本願に開示される回転電機は、固定子鉄心のスロットに挿通されるスロット挿通部とそれぞれのスロット挿通部を電気的に接続するコイルエンド部とからなるコイル単体を複数組み合わせて固定子巻線を形成するとともに、コイルエンド部の頂部において導電体を凹ませた凹部を設けたものである。【選択図】図３
