METHOD FOR ON-LINE DETECTION OF RESISTANCE-TO-GROUND FAULTS IN ACTIVE MAGNETIC BEARING SYSTEMS

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...
