  • Publication number: 20240336343
    Abstract: A propulsion system includes an electric motor assembly having an electric motor, a driveshaft, and a disconnect clutch. The disconnect clutch is structured to couple the driveshaft to an engine output shaft. The propulsion system further includes a fluid system having a cooling and lubrication fluid circuit fluidly connected to a first pump, and a clutch actuation fluid circuit fluidly connected to a second pump. The cooling and lubrication fluid circuit is fluidly connected to the clutch actuation fluid circuit via at least one of respective pump outgoing conduits from the first pump and the second pump or respective pump supply conduits to the first pump and the second pump. Related operating methodology is also disclosed.

  • Publication number: 20230198320
    Abstract: A stator is disclosed. The stator has a stator core that has stator poles protruding in a radial direction and a stator. The stator core has an axial groove formed on its outer surface along a longitudinal axis that is used to direct a cooling fluid from a first end of the stator core towards a second end of the stator core that is opposite the first end. Further, the stator core has an annulus groove formed on its outer surface, with the annulus groove in fluid communication with the axial groove. The annulus groove receives the cooling fluid from the axial groove, and is located between the first end and the second end of the stator core.
