A rotor (10) particularly for a high speed electric motor has a rare earth magnet core (12) within a sleeve (14) forming the rotor shaft. The core (12) is axially compressed between opposed end pieces (16, 18) secured to the sleeve by welding, adhesive or heat-shrinking. Radial compression may also be applied to the core (12). A method of assembly of the rotor (10) has the steps of axially compressing the core (12) between the end pieces (16, 18) and securing the sleeve (14) to the end pieces (16, 18) while the core (12) is pre-stressed.

La présente invention concerne un rotor (10), et plus particulièrement un rotor de moteur électrique grande vitesse, comportant un noyau magnétique (12) en terre rare à l'intérieur d'un manchon (14) formant l'arbre du rotor. Le noyau (12) est soumis à une compression axialement comprimé s'exerçant entre des pièces d'extrémités opposées (16, 18) fixées au manchon par soudure, par collage ou par thermorétraction. Le noyau peut également être soumis à une compression radiale. Le procédé d'assemblage du rotor (10) consiste en une opération de compression axiale du noyau (12) entre les pièces d'extrémités (16, 18) et une opération de fixation du manchon (14) aux pièces d'extrémités (16, 18) pendant que le noyau (12) est soumis à précontrainte.
