| Zusammenfassung: | To stabilize a natural frequency of a manufactured stator.SOLUTION: The present invention relates to a manufacturing method of a stator which is provided in a rotary electric machine. The manufacturing method includes: a core heating step S100 of heating a cylindrical stator core in which a plurality of slots are formed, and expanding the stator core; a coil inserting step S110 of inserting a conductor group consisting of a plurality of segment conductors into the slots of the heated stator core; and a core cooling step S120 of cooling the stator core to which the conductor group is inserted, and giving an interference between the slots and the conductor group.SELECTED DRAWING: Figure 8
【課題】製造されるステータの固有振動数を安定させる。【解決手段】回転電機に設けられるステータの製造方法であって、複数のスロットが形成された円筒形状の固定子コアを加熱し、固定子コアを膨張させるコア加熱工程Ｓ１００と、加熱された固定子コアのスロットに、複数のセグメント導体からなる導体群を挿入するコイル挿入工程Ｓ１１０と、導体群が挿入された固定子コアを冷却し、スロットと導体群との間に締め代を与えるコア冷却工程Ｓ１２０と、を有する。【選択図】図８ |
