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. |
