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.

Abstract: A process for making a hollow electrical coil for an electric motor includes forming a sacrificial insert material into a coil shaped insert. The coil shaped insert is placed into a copper plating bath and a copper plated coil shaped member is removed from the copper plating bath. The sacrificial material is removed from within the copper plated coil shaped member to create a hollow passage through a hollow copper coil shaped member. An exterior of the hollow copper coil shaped member is coated with an insulating adhesive material and the copper coil shaped member is compressed until the insulating adhesive material is set.

Abstract: A rotor core for an electric machine of an automobile includes a core stack including a plurality of lamination plates. Each lamination plate includes a plurality of apertures formed therein. The plurality of apertures of each of the lamination plates are axially aligned and define and a slot extending through the core stack and shaped to receive a corresponding insert. The rotor core also includes at least one insert received by the slot that provides radial structural stability to the plurality of lamination plates to prevent portions of the plurality of lamination plates adjacent the plurality of magnet slots from flexing due to radial forces exerted on the plurality of lamination plates during operation of the rotor core. The rotor core includes a load bearing polymer disposed within the aperture of the rotor core that provides contact between and the insert and the lamination plates.
