Modular Electromechanical Batteries for Storage of Electrical Energy for Land-Based Electric Vehicles
A compact magnetic bearing element for radial centering is described. At zero and low speeds, the centering occurs through mechanical contact of a rotating slotted pole structure with stretched metallic ribbons. At higher speeds, eddy currents induced in the metallic ribbons provide non-contacting centering forces. Exemplary uses for the invention are generally in rotating machinery and in flywheel energy storage systems.
