Title (EN) CONTROL OF MAGNETIZATION OF A MACHINE WITH AXIAL MAGNETIC BEARINGS
(FR) REGULATION DE MAGNETISATION D'UNE MACHINE POURVUE DE PALIERS MAGNETIQUES AXIAUX
Abstract: front page image
(EN)An axial magnetic bearing (10) includes a rotor (16) overlying a coil (32) in a stator (22). A second coil (40) is disposed at a location where it does not exert a significant force on the rotor (16). The second coil (40) generates a magnetic field to oppose and substantially cancel the stray magnetic field generated by the first coil (32).
(FR)Un palier magnétique axial (10) comprend un rotor (16) placé au-dessus d'une bobine (32) dans le stator (22). Une seconde bobine (40) est placée à un endroit où elle n'exerce pas une contrainte significative sur le rotor (16). La seconde bobine (40) génère un champ magnétique s'opposant au champ magnétique de dispersion généré par la première bobine (32) et l'annulant sensiblement.
