Abstract
A dynamoelectric machine has at least one end frame with a pair of opposite faces and a set of apertures intersecting with the opposite faces, respectively. A stator has a set of beams secured thereto for supporting the end frame against both axial and radial displacement with respect to the stator. The beams include a set of tabs protruding through the apertures in the end frame with the tabs each having a deformed portion engaged with the end frame within the apertures therein, thereby to retain the end frame against radial displacement with respect to the stator and another deformed portion engaged with one of the opposite faces of the end frame, thereby to retain the end frame against the axial displacement with respect to the stator, respectively.
