Summary:PROBLEM TO BE SOLVED: To provide a fixing device of a stator coil capable of reducing heat loss when heating a fixing member and reducing time required for curing the fixing member.SOLUTION: The fixing device of a stator coil fixes a stator coil 3 to be housed in an iron core slot 6 formed at an inner surface of a cylindrical stator iron core 1 of a rotary electric machine with a conforming material 4 as a fixing member that hardens at a temperature higher or equal to a predetermined temperature. The fixing device of the stator coil is installed near the iron core slot 6 and includes a plurality of hollow rod-like hot-water supply pipes 10 as heating members for heating the conforming material 4.SELECTED DRAWING: Figure 2 【課題】固定部材を加温する際の熱損失を低減させ、固定部材の硬化に要する時間を短縮可能な固定子コイルの固定装置を提供する。【解決手段】実施形態によれば、固定子コイルの固定装置は、回転電機の円筒状の固定子鉄心１内面に形成された鉄心スロット６内に収納される固定子コイル３を、所定温度以上で硬化する固定部材としてのコンフォーミング材４により固定する。この固定子コイルの固定装置は、鉄心スロット６の近傍に設置され、コンフォーミング材４を加温する加温部材としての複数の中空の棒状温水供給管１０を備える。【選択図】図２
