MAGNETIC BEARING

摘要

The invention relates to magnetic bearings. Said invention makes it possible to simplify the structural design for a bearing and to increase the reliability and service life thereof. The technical result is obtained by that a known device, comprising a body, shaft, stator and a rotor, which are positioned at an air gap with respect to each other, is provided with a stator embodied in the form of a hollow cylindric permanent magnet with axially oriented magnetization. The rotor also embodied in the form of a cylindrical magnet with axially oriented magnetization similar to the magnetisation of the stator. A left annular disc-like permanent magnet is arranged on the left of the rotor at an air gap. A right annular disc-like permanent magnet is arranged on the right of the rotor at an air gap. The end faces of the left and right annular magnets are oriented to the stator and rotor with the like poles thereof. The rotor is rigidly fastened to the shaft. The body is made of a non-magnetic material.
