Claim 20:
21. An electric compressor comprising:
a compressor portion having a rotational input;
an electric motor including a housing, a stator ring fixedly mounted to the housing, a rotor ring defined radially inward to the stator ring and being fixedly mounted to a shaft output that rotates about an axis, the shaft output being mechanically connected to the rotational input of the compressor portion; and
the stator ring extending along the axis from a first end to a second end and including a plurality of stator winding slots and a plurality of coolant slots that are spaced from the plurality of stator winding slots, wherein each cooling slot in the plurality of coolant slots extends from a first slot end to a second slot end along the axis, and wherein each of the coolant slots sharing an open edge with at least one corresponding stator winding slot such that coolant directly contacts a stator winding disposed in the corresponding stator winding slot, and wherein the coolant passes through the plurality of coolant slots in a direction along the axis and is expelled from at least one of the first slot end and second slot end into at least one cavity at one of the first end and the second end of the stator ring.
