Ultra-high-speed magnetic bearings
current magnetic bearings are based on reluctance forces. A magnetic flux in the air gap between the stator and rotor generates these forces, whereas the flux is regulated by stator currents. 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 a maximum of 120,000 rpm. To overcome... (read more)
