    Abstract: A stator includes a core and an over-molded midsection arranged to define a plurality of slots, and a plurality of conductors wound within the slots. Portions of the midsection immediately adjacent to the slots define a plurality of protrusions disposed on opposite long faces of at least some of the slots. The protrusions extend into the at least some of the slots and between some of the conductors to establish a gap between the some of the conductors and to direct coolant between the some of the conductors.

    Abstract: This disclosure relates to thermal management for an electric machine, such as an electric motor, of an electrified vehicle. An example assembly includes a stator having a core and a jacket at least partially surrounding the core. The jacket radially encloses a slot and is configured to permit fluid to flow within the slot from a first face of the stator to a second face of the stator. The assembly further includes a first end cover covering the first face of the stator. The first end cover has an inlet port and is configured to direct fluid from the inlet into the slot. Further, the assembly includes a second end cover covering the second face of the stator and configured to direct fluid that exits the slot.
