  • Publication number: 20250012352
    Abstract: A fluid flow system for a rotatable shaft assembly includes a first fluid flow device installed in a rotatable shaft, and a second fluid flow device installed in the rotatable shaft, spaced axially apart from the first fluid flow device. The first fluid flow device includes a wall portion having a radial dimension that retains oil in the rotatable shaft. The second fluid flow device includes a wall portion having a radial dimension that facilitates discharge of oil from the radial shaft. The first and second fluid flow devices each include a plurality of baffles on the respective wall portions thereof. The plurality of baffles drive the flow of fluid in an axial direction, from the first fluid flow device toward the second fluid flow device, as the first and second fluid flow devices rotate together with the rotatable shaft.

  • Publication number: 20240421665
    Abstract: A dual axial cooling system for an electric motor includes a cover assembly provided at first and second axial ends of a stator of the electric motor. Each cover assembly includes a first side portion that is oriented so as to face an interior of the stator, with a plurality of holes formed in the first side portion. A second side portion is coupled to the first side portion, so that a passage is formed between the first and second side portions. A supply nozzle portion is in fluid communication with the plurality of openings via the passage defined between the first and second side portions. The plurality of openings receive cooling fluid from the supply nozzle portion, and discharge the cooling fluid in an axial direction, from each axial end portion of the stator, to provide axial cooling in two axial directions into the stator.

  • Publication number: 20240072590
    Abstract: An electric motor comprises: a rotor; a stator comprising a stack of laminations, wherein windings of the stator comprise wires that have individual insulation, the wires forming slot windings positioned in slots of the stator, the wires further forming end windings positioned outside the slots at each end of the stator; varnish in the slots of the stator, the varnish contacting the laminations and the slot windings, and wherein the varnish does not contact the end windings of at least one of the ends of the stator; and a cooling system to apply liquid coolant to at least the end windings, wherein the liquid coolant passes between the wires of the end windings.

  • Patent number: 11462957
    Abstract: An electric motor cooling system is provided that utilizes stator-integrated axial coolant channels and a coolant manifold centrally located within the stator to efficiently remove motor assembly heat. In order to improve end winding cooling uniformity, two or more end laminations are included on either end of the stator assembly which restrict and direct the flow of coolant exiting the axial coolant channels.

  • Patent number: 11462958
    Abstract: An electric motor cooling system is provided that utilizes stator-integrated axial coolant channels and a coolant manifold centrally located within the stator to efficiently remove motor assembly heat. The coolant manifold includes a middle member that allows coolant to enter the axial coolant channels via transition laminations, where the transition laminations include coolant distribution channels that direct the flow of coolant entering into the manifold into the stator-integrated axial coolant channels.
