Rotors on Active Magnetic Bearings: Modeling and Control Techniques

The absence of all fatigue and tribology issues due to contact: it allows the use of such bearings in vacuum systems, in clean and sterile rooms, or for the transport of aggressive or very pure media, and at high temperatures;• No lubrication needed;• No contamination by the dust created by friction between the rotor and the stator;• Low bearing losses: at high operating speeds are 5 to 20 times less than in conventional ball or journal bearings, result in lower operating costs;
