Abstract

L'invention concerne un système d'ascenseur (2) comprenant un entraînement linéaire (4). L'entraînement linéaire est conçu pour déplacer une cabine (26) dans une cage d'ascenseur (20, 22). Le système d'ascenseur comprend en outre un accumulateur d'énergie (6) couplé à l'entraînement linéaire. Une unité de commande (8) peut, dans un premier état du système, alimenter de l'énergie de l'entraînement linéaire à l'accumulateur d'énergie et, dans un deuxième état du système, dégager de l'énergie de l'accumulateur d'énergie dans l'entraînement linéaire.
