Abstract

Systems and methods for electric machine cooling. The electric machine, in one example, includes a rotor that includes an outer circumferential surface with one or more spiral grooves, a stator that circumferentially surrounds the rotor and includes end windings, and an air passage radially extending from the stator to an air gap between the stator and the rotor. The electric machine further includes a cooling assembly configured to spray a coolant towards the end windings.
