Abstract

La présente invention concerne un moteur ou un générateur électrique, comprenant un dispositif de couplage agencé pour monter un rotor sur un stator. Le dispositif de couplage comprend un premier élément de couplage couplé à une première paroi radiale du rotor et un second élément de couplage couplé au stator, un premier et un deuxième palier étant montés entre le premier élément de couplage et le second élément de couplage afin de permettre au rotor et au stator de tourner l'un par rapport à l'autre. Le moteur ou le générateur électrique comprend également un agencement d'étanchéité, l'agencement d'étanchéité incluant un troisième palier monté entre une surface d'une seconde paroi radiale du rotor et le stator.
