Abstract

L'invention concerne un rotor (2) pour lequel la matière adhésive ou la résine (5) est durcie à la lumière, ce qui permet de raccourcir fortement le temps pour le durcissement de la matière adhésive ou de la résine (5) et de réduire nettement la consommation d'énergie. Selon l'invention, chaque poche (3) comprend au moins un volume de refoulement (10) qui permet d'amener la lumière jusqu'à la matière adhésive ou la résine (5) et qui réduit la quantité de matière adhésive ou de résine nécessaire à la fixation des aimants permanents (4).
