The subject of the invention is a magnetic bearing, composing a stator (1) and a rotor (2) with mandrel (5), and both its stator (1) and rotor (2) having permanent magnets arranged to provide repulsive radial and axial forces without control systems, centering magnets or sensors. Thereto it is proposed that the stator (1) of the magnetic bearing has at least two, basin-form shouldered bodies which are magnetised to opposing polarities and one of them - the bottom shouldered body - forms a basin (3), while the other - the upper shouldered body - forms a counter- basin (4), the magnetic fields of these shouldered bodies ensphere the rotor (2) of the magnetic bearing, the mandrel (5) is led through the central part of the rotor (2), the bottom part (6) of the rotor (2) is magnetised to a polarity identical with that of the upper surface (8) of the opposite basin (3) and the upper part (7) to the polarity of the bottom surface (9) of the similarly opposite counter-basin (4). |
