High Power Transfer Through Load-Supporting Bearings

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
A system for power transfer to a movable platform makes use of a capacitive interface in moving elements of load-supporting bearings for power transfer. Tank circuits associated with each bearing increase power transfer by reducing effective impedance of the small bearing capacitances.
