Abstract: A rotor for an electric machine includes a rotor body formed from a plurality of stacked laminations defining a first axial end and an opposing second axial end. Each of the plurality of stacked laminations includes a plurality of openings that are aligned so as to define a plurality of passages through the rotor body. A plurality of reinforcement elements extend through the plurality of stacked laminations. Each of the plurality of reinforcement elements is arranged in a corresponding one of the plurality of passages and includes a first end portion and a second end portion. The first end portion and the second end portion of select ones of the plurality of reinforcement elements extend outwardly of the first axial end and the second axial end.

Abstract: A rotor for a reluctance machine includes a rotor body having cavities defined by inner surfaces of the rotor body, a filler disposed within the cavities, and an adhesive coating that covalently bonds the filler to the inner surfaces of the rotor body. The adhesive coating exhibits a composite structure including a continuous matrix component and a discontinuous organic component dispersed throughout the matrix component, wherein the matrix component comprises an inorganic siloxane network and the organic component comprises a plurality of organic groups bonded to the inorganic siloxane network. The adhesive coating is formed on the inner surfaces of the rotor body by depositing a precursor composition on the inner surfaces of a rotor body and exposing the precursor composition to a plasma. The precursor composition comprises an organofunctional silane or a hydrolysate thereof.

Abstract: A vehicle, suspension system and method of dampening a force on the suspension system is disclosed. The suspension system includes a damper having a first damping element and a second damping element configured to rotate relative to each other in response to a force received at the suspension system. The second damping element induces an eddy current in the first damping element during relative rotation. A feature of one at least one of the first damping element and the second damping element provides a first electrical resistance to the eddy current during relative rotation in a first direction and a second electrical resistance to the eddy current during relative rotation in a second direction. The first electrical resistance generates a first damping force and the second electrical resistance generates a second damping force.
