To provide a high-torque low-noise rotary electric machine.SOLUTION: In a rotary electric machine 200, a jumper conductor 233b having a normal slot pitch connects a position between slot conductors 233a so as to stride slots 237 with a slot pitch Np=N(=6) in one coil end 241 and to stride the slots 237 with a slot pitch Np=N(=6) in the other coil end 241, assuming that the number of slots per a pole is set to N(=6). The jumper conductor 233b having an irregular slot pitch connects a position between the slot conductors 233a so as to stride the slots 237 with a slot pitch Np=N+1(=7) in one coil ends 241 and to stride the slots 237 with a slot pitch Np=N-1(=5) in the other coil end 241, assuming that the number of slots per a pole is set to N(=6). Stator winding 238 has a plurality of slot conductor groups 234 consisting of a plurality of slot conductors 233a having the same phase.SELECTED DRAWING: Figure 11
【課題】高トルクかつ低騒音である回転電機の提供。【解決手段】回転電機200において、通常スロットピッチの渡り導体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241ではスロットピッチNp=N(=6)でスロット237を跨ぎ、他方のコイルエンド241ではスロットピッチNp=N(=6)でスロット237を跨ぐようにスロット導体233a間を接続する。変則スロットピッチの渡り導体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241ではスロットピッチNp=N+1(=7)でスロット237を跨ぎ、他方のコイルエンド241ではスロットピッチNp=N−1(=5)でスロット237を跨ぐようにスロット導体233a間を接続する。固定子巻線238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を複数有する。【選択図】図11
