What do you think of when you hear the word “bearings?” Whether you envision rolling-element, plain, or thrust bearings, odds are that power sources, control electronics, and magnetic fields don’t enter the picture. But active magnetic bearings are replacing oil-lubricated bearings in many applications. Magnetic bearings support rotating machinery without contaminating or flammable lubricants and with high reliability, little or no maintenance, low frictional losses, less machine vibration, and improved monitoring and diagnostic capabilities. However, because they’re large, expensive. and require external controls — not to mention the complexity of integrating them into machinery — their applications have been limited to date.
