Abstract: An e-machine includes a housing with a cooling fluid inlet and a cooling fluid outlet. The e-machine includes a rotating group supported for rotation about an axis of rotation within the housing. The cooling fluid inlet and the cooling fluid outlet are disposed on opposite sides of the axis of rotation. The e-machine includes a stator disposed within the housing. The e-machine includes a plurality of nozzles in fluid communication with the cooling fluid inlet to receive a cooling fluid therefrom. The plurality of nozzles are arranged about the axis of rotation and generally toward the stator. The arrangement of the plurality of nozzles is directed generally in a circumferential direction with respect to the axis of rotation from the cooling fluid inlet to the cooling fluid outlet.

Abstract: A method for manufacturing a turbomachine shrouded wheel involves separately moulding a first green, moulded part forming a hub and blades, and a second green, moulded part forming a shroud, using a feedstock comprising a metal powder and a binder. The green, moulded parts are adjoined in a mated configuration, with additional feedstock placed between respective connection-surfaces on the moulded parts. The adjoined moulded parts are sintered to fuse them into a single unitary, monolithic structure. The moulded parts' connection-surfaces form conforming protrusions and depressions, which have surface discontinuities spaced at intervals along their respective lengths.
