Abstract

Rotor bobiné, notamment pour machine électrique, comprenant un arbre de rotation (12) fretté, sur une première portion cylindrique (12a) de l'arbre (12), dans un empilement (16) de tôles formant un noyau (14) et délimitée chacune par un contour extérieur (16a) et un alésage intérieur (16b). Le rotor (10) comprend une entretoise annulaire (18) disposée radialement dans ledit alésage intérieur (16b) entre l'arbre de rotation (12) et le noyau (14).Wound rotor, in particular for an electric machine, comprising a rotation shaft (12) shrunk onto a first cylindrical portion (12a) of the shaft (12), in a stack (16) of sheets forming a core (14) and delimited each by an outer contour (16a) and an inner bore (16b). The rotor (10) includes an annular spacer (18) disposed radially in said inner bore (16b) between the rotation shaft (12) and the core (14).
