An electric compressor motor includes a stator ring having a plurality of stator winding slots and a plurality of stator windings. Each of said stator windings is received in a stator winding slot of the plurality of stator winding slots. The stator ring also includes a plurality of cooling slots. Each cooling slot in the plurality of coolant slots is defined 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 coolant slot is defined. The cooling slots are configured to allow coolant to directly contact at least one stator winding in the corresponding at least one stator winding slot.
