Abstract
An example electric machine includes a rotor and a stator. The stator includes a stator core defining a longitudinal axis and a plurality of stator end windings extending from the stator core along the longitudinal axis. Adjacent end windings of the plurality of stator end windings define a radial gap, and the radial gap is configured to allow a cooling fluid to flow within the radial gap and in contact with the adjacent stator end windings.
