Abstract
An electric machine rotor assembly includes a rotor core defining a rotor axis. Windings are seated in the rotor core. A plurality of wedges circumferentially spaced apart around the rotor core relative to the rotor axis. Each rotor core extends axially and separates between two respective portions of the windings. A supply end plate is mounted at a first axial end of the rotor core. A return end plate is mounted at a second axial end of the rotor core opposite the first axial end. A flow path for coolant fluid extends through the supply end plate into the wedges, through the wedges and into the return end plate, and through the return end plate.
