ABSTRACT:
Each cooling pad includes a plurality of concentric cooling robes (24) prefabricated and cast within the cooling pad (20). The robes are formed of stainless steel and, prior to casting, are coated by a plasma spray process with aluminum to ensure an integral bond between the cast and sprayed aluminum and hence between the robes and the east pad to minimize or eliminate voids between the cooling robes and aluminum cooling pad. The inlets (26) and outlets (28) of the robes are coupled to inlet and outlet manifolds (32, 34), respectively, along the outer periphery of the cooling pad. The cooling pad is interspersed between stator core laminations and supplied with deionized water whereby the cooling pads cool the stator core.
