Abstract: An electric machine is provided herein that includes a stator assembly. The stator assembly includes a stator core having one or more lamination packages. The stator core can define an outer ring and a plurality of teeth extending from the outer ring. A cooling plate may be positioned adjacent to at least one of the one or more lamination packages. The cooling plate can define one or more channels therethrough. One or more windings can be arranged around one or more of the plurality of teeth of the stator core. A rotor can be operably coupled with the stator assembly. A cooling system can be fluidly coupled with the one or more channels of the cooling plate. The cooling system provides a cryogenic fluid through the one or more channels to cool the electric machine.

Abstract: A rotor is disclosed, which includes a plurality of axially extending slots disposed about the rotor; a plurality of conductors radially stacked within each of the axial slots; and an axially extending subslot at a radially inward end of each of the slots. In each slot, a cooling path is provided, extending radially outward from the subslot. The cooling path includes at least one manifold, each manifold including at least one ingress passage, at least one egress passage axially distanced from the ingress passage, and a plurality of axially extending passages in fluid connection at a first end with one of the at least one ingress passages, and at a second end with one of the at least one egress passages. Each of the plurality of axially extending passages is disposed at a different radial depth in the slot from each other axially extending passage.
