Abstract
Methods and systems for an electric machine. The electric machine includes, in one example, a stator with end windings and a stator core and a cooling assembly with a spray ring that is directly coupled to an axial face of the stator core. In the electric machine, the spray ring is configured to spray a coolant at the end windings and includes a first section that extends down the axial face of the stator core and a second section that extends axially away from the stator core.
