Summary:To provide a rotary electric machine with excellent productivity, which can suppress vibration of a frame and a bearing.SOLUTION: A rotary electric machine comprises: a stator 2; a rotor 1 which is arranged on a radial inside of the stator 2 and comprises a rotary shaft 10; a bearing 16 for supporting the rotary shaft 10; an intermediate frame 15 for supporting the stator 2; and a stator frame 8 for supporting the bearing 16 and the intermediate frame 15. The stator frame 8 comprises pedestals 83 at both ends in a width direction of a bottom. The pedestals 83 comprise upper faces 83a positioned above a bottom face of the stator frame 8. The intermediate frame 15 is fixed to the upper faces 83a of the pedestals 83.SELECTED DRAWING: Figure 4 【課題】フレームと軸受の振動を抑制することができ、製作性のよい回転電機を提供する。【解決手段】本発明による回転電機は、固定子２と、固定子２の径方向内側に配置され、回転軸１０を備える回転子１と、回転軸１０を支持する軸受１６と、固定子２を支持する中間フレーム１５と、軸受１６と中間フレーム１５を支持する固定子フレーム８とを備える。固定子フレーム８は、底部の幅方向の両端部に台座８３を備える。台座８３は、固定子フレーム８の底面より上方に位置する上面８３ａを備える。中間フレーム１５は、台座８３の上面８３ａに固定される。【選択図】図４
