Abstract
A stator for an electric rotating machine includes a hollow cylindrical stator core, a stator coil, an outer cylinder, and at least one restraint. The stator core is comprised of a plurality of stator core segments that are arranged in the circumferential direction of the stator core to adjoin one another in the circumferential direction. The stator coil is mounted on the stator core. The outer cylinder is fitted on the radially outer surfaces of the stator core segments so as to fasten the stator core segments together. The restraint is arranged on an axial side of the stator core and retained by the outer cylinder so as to restrain axial deformation of the stator core segments due to the fastening force of the outer cylinder.
