56,889 ABSTRACT OF THE DISCLOSURE Disclosed herein is a generator stator core including an apparatus for cooling the end regions thereof by employing radial and axial intersecting passageways in the stator core for receiving a cooling medium. The stator core comprises a plurality of spaced-apart adjacent packs formed from a plurality of laminated sheets, well known in the art. The invention adds to the existing art an apparatus that seals and isolates the intersections of the axial and radial passageways in a stator core. In one example, this is accomplished by pre-forming the outer lamination of a pack so that it is bent to form an opening that conforms with the axial passageway and firmly engages the adjacent pack, thereby isolating the axial passageways from the radial passageways at the intersec- tion thereof. In other examples, such isolation is caused by placing conduits along the axial passageways between adjacent laminations.
