Abstract
Abstract A dynamoelectric machine is provided with a stator having windings therein, a rotatable assembly disposed in the stator, and at least one end shield for supporting the rotatable assembly. A plurality of beams on the stator respectively have at least a portion for mounting with the end shield, and a plurality of sockets are provided in the end shield for receiving the beam portions and into which they extend generally in spaced relation with at least a portion of the end shield about the sockets. Metallic plugs are solidified and contained generally within the sockets and are respectively interconnected between the beam portions and and at least a portion of the sockets for rigidly mounting the end shield and the stator.
