Abstract

A dynamo-electric machine which inhibits the vibration of a frame and a bearing and has excellent manufacturability. A dynamo-electric machine according to the present invention includes a stator, a rotor including a rotary shaft and being disposed on an inner side in a radial direction of the stator, a bearing for supporting the rotary shaft, an intermediate frame for supporting the stator, and a stator frame for supporting the bearing and the intermediate frame. The stator frame includes pedestals at two end portions in a width direction of a bottom portion of the stator frame. Each of the pedestals includes an upper surface positioned above a bottom surface of the stator frame. The intermediate frame is fixed to upper surfaces of the pedestals.
