Abstract

L'invention concerne un rotor A de machine tournante M comprenant un arbre rotor 1 comprenant un axe de rotation X et un dispositif encodeur magnétique 3 fixé à l'arbre rotor 1. Le dispositif encodeur 3 comprend une tige de fixation 31 fixée dans un trou 12 de l'arbre rotor 1, un support en matériau amagnétique 32 fixé à la tige de fixation 31 et un encodeur magnétique 33 fixé au support 32. L'encodeur 33 comprend un rayon maximum R33 par rapport à l'axe de rotation X, le support 32 séparant l'encodeur magnétique 33 de l'arbre rotor 1. Le rotor comprend en outre un bouclier 4 de champ magnétique, en matériau magnétique. Le bouclier 4 comprend une ouverture axiale 41 traversée par la tige de fixation 31 et est en contact avec l'arbre rotor 1. Le rayon externe maximum encodeur R33 de l'encodeur magnétique 33 est inférieur à un rayon externe maximum bouclier R4 du bouclier 4.
