Claim 0:
1. An electric compressor motor comprising:
a stator ring surrounding an axis and extending along the axis from a first end to a second end, the stator ring including a plurality of stator winding slots and a plurality of stator windings, wherein each of said plurality of stator windings is received in a stator winding slot of the plurality of stator winding slots;
a plurality of cooling slots, spaced from the plurality of stator winding slots, and which each extend from the first end to the second end of the stator ring, each cooling slot in the plurality of cooling slots extending from a first slot end to a second slot end along an axial length of at least one corresponding stator winding slot of the plurality of stator winding slots such that a shared opening between each stator winding slot and at least one corresponding cooling slot is defined;
wherein the plurality of cooling slots are configured to allow coolant to directly contact at least one stator winding in the corresponding at least one stator winding slot; and
wherein the coolant passes through the plurality of cooling 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.
