Magnetic Bearings ~ Celeroton AG - Ultra-high-speed

Functional principle of an active magnetic bearing. In this magnetic bearing type, the rotational speed is limited due to increasing eddy current losses in the rotor and stator iron, a limited actuator bandwidth and a high reactive power demand. Therefore, magnetic bearings have only been successful up to rotational speeds of about 120,000 rpm.
