A rotating elevator motor provided with a traction sheave is placed in the counterweight of an elevator suspended with ropes. A gear system is not necessary because the structure and placement of the motor allow the use of a motor having a large diameter and a high torque. As the length of the motor still remains small, the motor/counterweight of the invention can be accommodated in the space normally reserved for a counterweight in the elevator shaft. The motor shaft lies in the counterweight substantially midway between the guide rails and the number of ropes is equal on both sides of the plane going through the centre lines of the guide rails.
Un moteur rotatif d'ascenseur doté d'une poulie de traction est placé dans le contrepoids d'un ascenseur suspendu par des câbles. Un train d'engrenages n'est pas nécessaire, car la structure et l'emplacement du moteur permettent d'utiliser un moteur à grand diamètre et à couple élevé. La longueur du moteur demeurant faible, le moteur/contrepoids de l'invention peut être logé dans l'espace normalement réservé à un contrepoids dans la gaine d'ascenseur. L'arbre du moteur est situé dans le contrepoids essentiellement à mi-chemin entre les rails-guides, et le nombre de câbles est égal des deux côtés du plan passant par les axes des guides-rails.
