Abstract
Palier comprenant un corps porté rotatif autour d'un axe par rapport à un corps porteur, chacun de ces corps comportant une surface de portée tournée vers l'autre et un palier auxiliaire entre en action au moins pendant la montée en vitesse à partir du repos et pendant le retour au repos du corps porté. Le palier auxiliaire est à aimants permanents. Application en particulier aux paliers dont l'arbre doit tourner à très grande vitesse, par exemple aux turbines à expansion.
