SOLUTION OF CONTACT-FREE PASSIVE MAGNETIC BEARING

Daniel Mayer - Vít Veselý

   The submitted paper deals with a simple method allowing easy calculation of static characteristics of passive radial or axial permanent magnetic bearings. There are two ways leading to an increase of the loading capacity: by asymmetrical arrangement of the bearing, or by its shielding with the help of a ferromagnetic jacket. The calculation algorithm is illustrated by numerical examples.

Keywords: passive magnetic bearing, application of permanent magnets, magnetic levitation, stiffness of magnetic bearing.
