Classification: CPC H  B | IPC B  H

Claim 0:
1. An electric machine comprising:
a stator assembly, the stator assembly comprising:
a stator core including one or more lamination packages, the stator core defining an outer ring and a plurality of teeth extending from the outer ring;
a cooling plate positioned adjacent to at least one of the plurality of lamination packages, wherein the cooling plate defines one or more channels therethrough, wherein the one or more channels includes a plurality of tributaries extending within one or more teeth of the plurality of teeth, wherein the plurality of tributaries is in fluid communication with the one or more channels, wherein the cooling plate is formed through an additive manufacturing process, wherein one or more exterior surfaces of the cooling plate are treated to increase thermal contact conductance and decrease electrical contact conductance; and

one or more windings arranged around one or more teeth of the stator core;
a rotor operably coupled with the stator assembly; and
a cooling system fluidly coupled with the one or more channels of the cooling plate, wherein the cooling system provides a cryogenic fluid through the one or more channels.
