The thesis deals with the design of a hybrid magnetic bearing. This is an extension of the issue of common bearings in high-speed motors. The work is divided into three parts. A general theory of magnetic bearings is described in the first part. The second part deals with the mathematical description of the bearing. A proposal of specific hybrid magnetic bearing is described in the third part. The bearing for the motor was already designed. It is a 45000rpm motor with a power output of 12 kW. This thesis aims to create a design of hybrid magnetic bearing with magnets to create a permanent magnetic field and coils to regulate forces to stabilize the rotor and limit vibrations. The practical design includes mathematical calculation in Matlab and computer simulation based on the finite element method in ANSYS Maxwell.
