    Abstract: The present disclosure provides a superconducting magnetic bearing as support system between two relatively movable parts (1, 2). One of the parts (2) includes a superconducting unit comprising at least one superconducting element (19) and a cryostat (25) with a housing (22). The at least one superconducting element (19) is provided inside the housing (22) of the cryostat (25). The other part (1) comprises at least one magnetic field generating element (21). The superconducting unit (19, 22, 25) and the magnetic field generating element (21) are arranged so that one of the superconducting unit (19, 22, 25) and the magnetic field generating element (21) is contactlessly supportable through interaction of the superconducting element (19, 22, 25) and a magnetic field generated by the magnetic field generating element (21). To damp vibrations and to reduce the generation of heat in the superconducting element (19) at least one electrically conductive layer (28a) is arranged between the at least one superconducting element (19) and the magnetic field generating element (21) as eddy current damper.

    Abstract: A magnetic bearing is disclosed that includes a sensing wire wrapped around one or more of the bearing coils and configured to measure the resistance to ground of each bearing coil. With the presence of contaminants such as liquids, a protective coating disposed about the bearing coils degrades over time, thereby reducing the resistance to ground of the bearing coils. The sensing wire transmits the detected resistance to ground of the bearing coils to an adjacent sensing device, which can provide an output that informs a user whether corrective action is required to prevent damage or failure of the magnetic bearing.
