Zusammenfassung:To obtain a rotary electric machine in which the insulating quality of winding is improved.SOLUTION: In each of a plurality of unit coils, a coil slot section and a coil oblique section each have a rectangular cross section. The circumferential thickness and the radial thickness, in a cross section, of the coil slot section are constant over the whole area in the longitudinal direction. The circumferential thickness and the radial thickness, in a cross section, of the coil oblique section are respectively equal to or less than the circumferential thickness and the radial thickness, in a cross section, of the coil slot section. The curvature radius of a corner portion in a cross section of the coil oblique section is greater than the curvature radius of a corner portion in a cross section of the coil slot section.SELECTED DRAWING: Figure 2 【課題】この発明は、巻線の絶縁品質が向上された回転電機を得る。【解決手段】複数の単位コイルのそれぞれは、コイルスロット部およびコイル斜辺部の断面が矩形であり、上記コイルスロット部の断面における周方向厚みと径方向厚みが、長さ方向の全域で一定であり、上記コイル斜辺部の断面における周方向厚みと径方向厚みが、それぞれ、上記コイルスロット部の断面における周方向厚みと径方向厚み以下であり、上記コイル斜辺部の断面における角部の曲率半径が、上記コイルスロット部の断面における角部の曲率半径より大きい。【選択図】図2
