Abstract

La présente invention concerne un treuil destiné à un ascenseur et conçu de telle manière qu'une poulie d'entraînement (8) fixée à un arbre rotatif (21) soit disposée entre une première section (12) de support et une seconde section (13) de support, la première section (12) de support et la seconde section (13) de support étant situées à une certaine distance l'une de l'autre dans la direction horizontale. Un moteur présente un stator cylindrique (25) qui est fixé à la première section de support et un rotor (26) qui est fixé à l'arbre rotatif à l'intérieur du stator et qui est mis en rotation par rapport au stator. Le moteur est disposé sur le côté opposé de la première section (12) de support depuis la poulie d'entraînement (8). Un corps de suppression de déformation (23) destiné à supprimer la déformation élastique du stator, dont la dimension radiale change, présente un élément d'amortissement de vibrations (41) placé sur le stator.
