Abstract: A stator for a dynamoelectric machine includes a stator frame including a main frame and axial ribs cylindrically arranged in the main frame to extend parallel with an axis of rotation of a rotor such that a space is defined. The main frame includes a bottom wall, side walls standing from both radial ends of the bottom wall respectively, and connecting walls standing from both axial ends of the bottom wall and interconnecting both ends of the side walls, respectively. Each axial rib has opposite ends connected to the respective connecting walls and an intermediate portion between the ends. The intermediate portion of each axial rib is spaced away from the side walls. A stator core is formed of a stack of laminations of steel sheets and fitted in the space defined by the axial ribs to be held in position.
