1. A method for cooling an electric motor, comprising:
feeding coolant through a center of a rotating rotor shaft from a first end of a rotor towards a second end of the rotor;
flowing coolant outward from the rotor shaft on the second end of the rotor;
directing the outward flowing coolant toward axial holes in the rotor;
flowing coolant through the axial holes toward the first end of the rotor; and
directing coolant from the axial holes into an output-end balance plate on the first end of the rotor, the coolant flowing through the output-end balance plate radially inwardly, then longitudinally with the rotor shaft, and then exiting the output-end balance plate external to a housing of the electric motor.
