Abstract: Un dispositif de centrage magnétique, selon un axe de référence Z-Z, d'un second corps (B) mobile par rapport à un premier corps (A) comporte : - un palier magnétique (10) actif selon l'axe de référence, - deux centreurs magnétiques (20, 30) décalés axialement, le long de cet axe, de part et d'autre du palier magnétique.

Abstract: Magnetic bearing for the active magnetic centring, in at least one axis, of a mobile body according to another body perpendicular to a reference axis (Z-Z) of a body (B,B',B'',BB) which can move with respect to another body (A, A',AA), comprising, on each side of a plane of symmetry perpendicular to the centring axis, and containing the reference axis, at least one permanent magnet (3,3';3-3') magnetised parallel to the reference axis; at least one coil (9,9') wound around a ferromagnetic core (4,4') directed parallel to the reference axis; the magnet (3,3') and the core (4,4') about which the coil (9,9') is wound are gripped between two ferromagnetic plates (1,2; 1',2'; 1-1',2-2') carried by the said other body, whilst the mobile body carries a polar ferromagnetic piece (6,6') adapted so as to turn back on themselves, via the said air gaps (7,8; 7',8'), the magnetic fluxes circulating in the ferromagnetic plates. … …
