ROTARY ELECTRIC MACHINE STATOR

To reduce the number of assembly times while reducing spatial harmonics.SOLUTION: A rotary electric machine stator includes a stator core, and a stator coil in which a plurality of triple-wound coils concentrically including three coil portions in a closed coil shape when viewed in the radial direction are wound around the stator core for each phase. Each of the three coil portions in one triple-wound coil forms a closed coil shape by slot insertion portions on both sides in the circumferential direction, and transition portions on both sides in the axial direction, and the three coil portions include a first coil portion having the longest circumference, a second coil portion having a circumference shorter than that of the first coil portion by a pitch of four slots, and a third coil portion having a circumference shorter than that of the first coil portion by a pitch of two slots, and the plurality of triple-wound coils are inserted into respective corresponding slots in such a manner in which the first coil portions are radially adjacent and the second coil portions are radially adjacent.SELECTED DRAWING: Figure 1 【課題】空間高調波の低減を図りつつ、組み付け回数の低減を図る。【解決手段】１つの側面では、ステータコアと、径方向に視て閉じたコイル形状の３つのコイル部分を同心状に含む複数の三重巻コイルが、相ごとにステータコアに全周にわたり巻装されるステータコイルとを含み、一の三重巻コイルにおける３つのコイル部分は、それぞれ、周方向両側のスロット挿入部と、軸方向両側の渡り部とにより、閉じたコイル形状を形成し、３つのコイル部分は、周長が最も長い第１コイル部分と、周長が第１コイル部分よりも４スロット分のピッチだけ短い第２コイル部分と、周長が第１コイル部分よりも２スロット分のピッチだけ短い第３コイル部分とからなり、複数の三重巻コイルは、第１コイル部分同士が径方向で隣接しかつ第２コイル部分同士が径方向で隣接する態様で、対応する各スロット内に挿入される、回転電機用ステータが開示される。【選択図】図１
