摘要： 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.
