Dynamics of permanent magnetic bearing
Půst, Ladislav
The basic analysis of radial bearings properties including nonlinear 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.

Permanent and active magnetic bearings
Kozánek, Jan ; Stolařík, M. ; Šafr, M.
In this paper, the design of a permanent contactless radial bearings was studied. The motor will be used as dynamic stand for further research in the field of vibration and stability problems in rotor dynamics. Due to insufficient reliability of analytical calculation of permanent magnet forces, preliminary measurements on a simple device were performed. The results obtained were used for the dimensioning of the bearings to be designed.

Rayleigh´s field in dynamics
Kozánek, Jan ; Scopel, D.
The method of analysis of the mathematical models of non-conservative and non-symmetric dynamic systems is presented. We seek a global insight into dynamic properties of the investigated system with help of the Rayleigh's Field of Values in complex plane.
