Claim 13:
14. A method for cooling an electric motor comprising:
injecting a coolant into a coolant slot defined within a stator lamination of an electric motor, wherein the stator lamination surrounds an axis and extends along the axis from a first end to a second end of the stator lamination, and wherein the coolant slot extends from a first slot end at the first end of the stator lamination to a second slot end at the second end of the stator lamination;
passing the coolant through the coolant slot along an axial length of the stator lamination such that the coolant directly contacts at least one stator winding disposed in a corresponding stator winding slot that is spaced from the coolant slot; and
passing the coolant through the coolant slot in a direction along the axis and expelling the coolant from one of the first slot end or second slot end into at least one cavity at one of the first end and the second end of the stator lamination.
