Abstract
A wedge for use in a generator rotor has a wedge body with a central radially top surface of the wedge body, formed with a plurality of blades. At least some of the plurality of blades extend at an angle such that a plane defined through the blades will be non-perpendicular to a rotational axis of the rotor that will receive the wedge.
