PROBLEM TO BE SOLVED: To provide a rotary electric machine that can be reduced in noise.SOLUTION: In a rotary electric machine comprising a stator winding having a plurality of corrugated circumferential windings and a rotator supported rotatably on a stator core 232 via a clearance, when the number of slots in each pole is set as N (=6), a crossover conductor 233b connects the slot conductors to each other so as to stride over a slot at slot pitch Np=N+1 (=7) at one coil end and to stride over the slot at slot pitch Np=N-1 (=5) at the other coil end. The stator winding has a plurality of slot conductor groups constituted of a plurality of slot conductors 233a with the same phase, and the plurality of slot conductors 233a of the slot conductor groups 234 are inserted through a predetermined number Ns of slots arrayed consecutively in a circumferential direction of the stator core so that a slot 237 and layers L1-L4 are adjacent, where the predetermined number Ns of slots is set to Ns=NSPP+NL(=4) when the number of slots in each pole and each phase is set as NSPP(=2) and the number of layers is set as 2×NL(=4).
【課題】低騒音化を図ることができる回転電機の提供。【解決手段】波巻の周回巻線を複数有する固定子巻線と、固定子コア232に対して空隙を介して回転自在に支持された回転子とを備える回転電機において、渡り導体233bは、毎極スロット数をN(=6)としたとき、一方のコイルエンドではスロットピッチNp=N+1(=7)でスロットを跨ぎ、他方のコイルエンドではスロットピッチNp=N−1(=5)でスロットを跨ぐようにスロット導体間を接続し、固定子巻線は、同一相の複数のスロット導体233aで構成される一群のスロット導体群234を複数有し、スロット導体群234の複数のスロット導体233aは、固定子コア周方向に連続して並んだ所定数Nsのスロット内にスロット237およびレイヤL1~L4が隣接するように挿通され、所定スロット数Nsは、毎極毎相スロット数をNSPP(=2)、レイヤ数を2?NL(=4)としたとき、Ns=NSPP+NL(=4)に設定されている。【選択図】図10
