Abstract

The construction of passive magnetic bearings is shown in the paper. Advantages and disadvantages a passive magnetic bearing with magnets, superconductors and electro-dynamic bearing are presented by Authors. They discus influence such parameters as load, speed of rotor, temperature and cost design and exploitation of bearing. Here are presented construction of the passive magnetic suspension designed for jet engines and linear bearing for UAV’s launchers.
