An active magnetic bearing (AMB) uses electromagnetic actuators in order to control the position of the rotor or levitated object in general. Any degree of freedom can be stabilized using an AMB …
Passive Bearings

Passive magnetic bearings (PMB) achieve contact-free levitation of an object by permanent magnetic attractive or repulsive forces. Depending on the configuration, stabilization in radial, axial…
Hybrid / Bearingless
