Magnetic Bearings - an overview | ScienceDirect Topics

Magnetic Bearings. Magnetic bearings react differently than hydrodynamic or rolling-element bearings in that the mechanical bearings react immediately to a load change while the magnetic bearing in line with the load change must increase its force at the same rate to maintain rotor position. From: Compressors (Third Edition), 2005.
