Active magnetic bearings (AMBs) present unique advantages over conventional roller or fluid-film bearings when designing high-speed rotating machinery, such as turbines, compressors, Organic Rankine Cycle systems and flywheel energy storage systems. Unlike conventional bearings, AMBs suspend the target rotor in a magnetic field. The result is a non-contact rotor support system with extremely low friction and no contact wear.
What follows is a simplified explanation of how active magnetic bearings work and how they can benefit high-speed rotating equipment.
