Dynamics of permanent magnetic bearing
Půst L.
pages 231 - +8p, full text

In comparison with the active magnetic bearings, the advantage of passive (permanent) bearings is their simplicity and very low damping, but they can introduce instability of rotor position. Therefore the basic analysis of radial bearings properties including non linear characteristics are presented. The mathematical models of vertical and horizontal rotors supported by permanent magnetic bearings are derived. Splitting of resonance's due to the rotor weight and existence higher harmonics are mentioned as well.
