ROTARY ELECTRIC MACHINE

PROBLEM TO BE SOLVED: To provide a rotary electric machine that makes an insulating system material inside a slot of a stator coil have higher thermal resistance and has excellent electric insulation at a high temperature.SOLUTION: The rotary electric machine, which has a stator coil that is cured after injecting impregnated resin into the whole of a single stator coil in which a single electric insulation coil having a mica tape 4 wound around a conductor 3 is installed in a slot 2 of a stator core 1 through a slot liner 5, has epoxy resin having at least three epoxide groups as a high thermal resistance resin component of the slot liner and has at least alicyclic epoxy resin as a high thermal resistance resin component of the mica tape. The impregnated resin has an acid curing agent having bifunctional epoxy resin and one acid anhydride skeleton. The high thermal resistance resin components of the slot liner and the mica tape and the impregnated resin are integrated as a liner curing part and a mica insulating layer part in the slot, with different resin compositions thereof. 【課題】固定子コイルのスロット内部の絶縁システム材料を高耐熱化し，高温の電気絶縁性に優れた回転電機を提供する。【解決手段】導体３の周囲にマイカテープ４を巻回した電気絶縁線輪単体を，スロットライナ５を介して固定子鉄心１のスロット２に組込んだ固定子コイル単体全体に，含浸レジンを注入後に硬化した固定子コイルを有す回転電機において，スロットライナの高耐熱樹脂成として少なくともエポキシ基を三つ以上有するエポキシ樹脂を有し，マイカテープの高耐熱樹脂成分として少なくとも脂環式エポキシ樹脂を有し，含浸レジンは二官能エポキシ樹脂と酸無水物骨格を一つ有する酸硬化剤を有し，スロットライナおよびマイカテープの高耐熱樹脂成分と含浸レジンが，スロット内でライナ硬化部とマイカ絶縁層部として樹脂組成が異なる状態で一体となることを特徴とする固定子コイルを有す回転電機。【選択図】図１
