A vehicle propulsion system includes a rotor shaft defining a cavity within the rotor shaft and a radial hole extending from the cavity to an external surface of the rotor shaft, and a restrictor that reduces a flow of liquid through the radial hole in response to a rotational speed of the hollow rotor shaft exceeding a predetermined threshold rotational speed.
