Zusammenfassung: | To provide a stator of a rotary electric machine, a rotary electric machine and a manufacturing method of a stator that can reduce production cost.SOLUTION: In a stator 1 including a coil 5 with a plurality of segment coils 18 wound around a slot 2, the segment coils 18 have two linear parts 91, 92 arranged respectively within two slots 2 spaced at a predetermined number in a circumferential Z and a crossover part 10 connecting the two linear parts 91, 92 together on one end side in an axial direction Y of a core 3. The linear parts 91, 92 of the segment coils 18 have polygonal shapes of which a cross-sectional shape perpendicular to the axial direction Y is a polygon of at least a quadrangle and is formed so that a length L1 of one diagonal 151 connecting corners 141, 143 together in the cross-sectional shape and a length L2 of one diagonal 152 connecting other corners 142, 144 together are different.SELECTED DRAWING: Figure 4
【課題】生産コストを低減できる回転電機のステータ、回転電機、および、ステータの製造方法を提供する。【解決手段】複数のセグメントコイル18がスロット2に巻装されたコイル5とを備えるステータ1において、セグメントコイル18は、周方向Zにおいてあらかじめ設定された個数離れた2カ所のスロット2の内部にそれぞれ配置される2つの直線部91、92、および、コア3の軸方向Yの一端側において当該2つの直線部91、92同士をつなぐ渡り部10を有し、セグメントコイル18の直線部91、92は、軸方向Yに垂直な断面形状が4角形以上の多角形の形状を有し、断面形状において角部141、143同士をつなぐ1つの対角線151の長さL1と、他の角部142、144同士をつなぐ1つの対角線152の長さL2とが異なって形成される。【選択図】図4 |
