    Abstract: An electric machine includes a housing and a stator mounted to the housing. The stator includes a plurality of laminations, a first end turn and a second end turn. A rotor shaft extends through the housing. A hybrid rotor module is coupled to the rotor shaft. The hybrid rotor module includes a clutch basket including a rotor carrier having a first end, a second end, and an intermediate portion extending therebetween. The first end is radially outwardly offset relative to the second end. One or more clutch assemblies is arranged in the clutch basket. A rotor mounted to the rotor carrier. One or more openings is formed in the rotor carrier. The one or more openings direct coolant onto at least one of the stator, the first end turn, and the second end turn.

    CPC classification number: H02K9/19 ,  H02K5/20

    Abstract: A stator housing has an annular wall including a first end, a second end, an outer surface and an inner surface defining an interior cavity. A stator is arranged within the interior cavity. The stator includes an outer surface portion, a first end turn and a second end turn. A coolant annulus extends about at least a portion of the stator housing. The coolant annulus includes at least one coolant spray passage arranged to direct a spray of coolant at one of the first end turn and the second end turn. A coolant seal and distributor is coupled to the stator housing at the first end sealing against the stator. The coolant seal and distributor includes one or more coolant spray nozzles arranged to direct a spray of coolant onto the other of the first end turn and the second end turn.
