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.

摘要： A system, method, and apparatus for damping vibration in a rotor supported by primary bearings are provided. The system includes a magnetic coupling configured to magnetically engage a rotor supported by one or more primary bearings, and a piston coupled to the magnetic coupling. The system also includes a damper engaging the piston and configured to damp the rotor, wherein the damper is substantially non-load bearing.

摘要： A resistance to ground monitoring system for a magnetic bearing is disclosed. The system includes a dummy bearing arranged in a cooling loop and having a dummy bearing coil made up of an electrical winding that is configured to detect the resistance to ground for the dummy bearing coil. The electrical winding is communicably coupled to a sensing device that monitors the resistance to ground for the dummy bearing coil. Since the magnetic bearing is arranged within the same cooling loop, the resistance to ground for the dummy bearing coil is indicative of a resistance to ground for the radial bearing coils of the magnetic bearing.

摘要： A drive pin mechanical fastener is disclosed and has an elongate body extending from a head. A frustoconical indicator shroud is disposed about the elongate body and has a first end and a second end. The first end of the indicator shroud is arranged about the elongate body proximate the head and the second end extends away from the head. The indicator shroud is movable from a first position, where the indicator shroud is frustoconical, to a second position, where the indicator shroud is flattened and exposed and thereby provides an indicator to an installer that the drive pin is properly installed.
