A motor-generator set stator core includes a plurality of flat thin annular winding support plates, a pair of improved annular end plates, and a plurality of elongated flat attachment members for retaining the end plates and support plates assembled together. The improved annular end plates have substantially right triangular configurations in cross-section which are the reverse or a mirror image of one another. At hypotenuses of the right triangular cross-sections of the end plates are inner surfaces which have tapered or conical configurations that are the reverse of one another so as to conform to the outside tapered profile of the end turns of the stator windings. At short sides of the right triangular cross-sections of the end plates are radial planar surfaces which engage the opposite outer side portions of the stacked support plates. At long sides of the right triangular cross-sections of the end plates are circumferential cylindrical outer surfaces which connected at their inner ends with the radial planar surfaces. Each end plate has an annular radially outwardly projecting flange formed at the outer ends of the circumferential outer surfaces of the end plates. Each end plate has an annular cooling water-carrying channel of substantially triangular cross-section defined therein which is continuous around the entire annular extent of the end plate and a plurality of circumferentially-spaced orifices extending between the channel and the outer surface of the end plate.
