To improve the efficiency and output of a rotary electric machine without increasing the physique of it.SOLUTION: A rotary electric machine has a plurality of segment coils arranged in each of a plurality of layers aligned in a radial direction in a slot of a stator core. The segment coil has a linear section arranged in the slot, first area sections 111, 121 having a projection section projecting out of the slot from one end side of the linear section, and second area sections 112, 122 that extend from the other end of the linear section toward one side in the circumferential direction and being formed so as to change its position in a radial direction outside the slot of the other end side of the linear section. A tip end portion of the second area section 112 of the first segment coil 110 arranged at a predetermined layer in a predetermined slot is disposed so as to be radially adjacent to a tip portion of the first area section 121 of the second segment coil 120 arranged in the predetermined layer in the slot adjacent to the predetermined slot and being connected thereto.SELECTED DRAWING: Figure 2B

    【課題】体格を大きくすることなく、回転電機の効率および出力を向上させる。【解決手段】回転電機は、固定子コアのスロット内において径方向に一列に並ぶ複数のレイヤのそれぞれに配置される複数のセグメントコイルを有する。セグメントコイルは、スロット内に配置される直線部、および直線部の一端側からスロット外に突出する突出部を有する第1領域部111,121と、直線部の他端側のスロット外において、直線部の他端側から周方向一方に向かって延びるとともに径方向における位置が変化するように形成される第2領域部112,122と、を有する。所定スロット内の所定レイヤに配置される第1セグメントコイル110の第2領域部112の先端部は、上記所定スロットに隣接するスロット内の上記所定レイヤに配置される第2セグメントコイル120の第1領域部121の先端部と径方向で隣り合うように配置され、接続される。【選択図】図2B
