An electric motor assembly includes a shield that extends about a sector of the winding head to be disposed axially outboard of the outer axial end of the winding head and radially inboard of the inner diameter portion of the winding head. The shield defines a reservoir in which the sector of the winding head is received. The reservoir is operable to receive the coolant for cooling the winding head. Additionally, the motor assembly includes at least one sealing member that substantially seals at least one of the slots formed in an inner diameter portion of the stator core. The sealing member is operable to contain the coolant within the corresponding longitudinal opening and the reservoir.
