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...
1. A magnetic bearing, comprising: a stator having a plurality of protrusions extending radially-inward therefrom and electrical windings wound about each protrusion to form a corresponding plurality of bearing coils, the plurality of bearing coils being disposed within an insulative coating adapted to protect against the ingress of liquids;a controller communicable with the electrical windings and configured to control an electrical current in each bearing coil to maintain a rotor centered within the stator;a sensing wire coupled to at least one of the ...
