ABSTRACT:
A method of fabricating a dynamo-electric machine rotor is provided. The method includes forming a plurality of laminations, such that a plurality of openings extend through the laminations between an outer peripheral edge and an inner peripheral edge arcuately spaced about the lamination wherein each opening includes an edge with a tongue that extends into the opening, stacking the laminations to form a core wherein adjacent opening are substantially aligned to form a slot in the core and filling the core slots with rotor bar material.
