Abstract
(EN)
The present invention relates to an elevator traction machine comprising an eddy current brake, and suppresses, in an emergency of electrical shutdown, rotation of a rotor so as to reduce the falling speed of an elevator. An elevator traction machine according to the present invention comprises: a motor which includes a rotor and a stator and transfers a rotation force through the rotor; a sheave which is installed at the rotor and around which a winding rope is wound so as to enable longitudinal movement of an elevator car subjected to be suspended by the winding rope; a brake which mechanically comes into contact with the rotor according to an electrical signal so as to stop rotation of the rotor; and an eddy current brake which suppresses, in an emergency of electrical shutdown, rotation of the rotor by means of a frictional force generated when the eddy current brake mechanically comes into contact with the rotor by using an eddy current generated by the motor.

La présente invention concerne une machine de traction d'ascenseur qui comprend un frein magnétique, et qui supprime, en cas d'urgence de coupure de courant, la rotation d'un rotor de manière à réduire la vitesse de chute d'un ascenseur. Une machine de traction d'ascenseur selon la présente invention comprend : un moteur qui est pourvu d'un rotor et d'un stator et qui transfère une force de rotation à travers le rotor ; une poulie qui est installée au niveau du rotor et autour de laquelle un câble d'enroulement est enroulé de manière à permettre le mouvement longitudinal d'une cabine d'ascenseur destinée à être suspendue par le câble d'enroulement ; un frein qui vient mécaniquement en contact avec le rotor en fonction d'un signal électrique de manière à arrêter la rotation du rotor ; et un frein magnétique qui supprime, en cas d'urgence de coupure de courant, la rotation du rotor par l'intermédiaire d'une force de frottement générée lorsque le frein magnétique vient mécaniquement en contact avec le rotor au moyen d'un courant de Foucault généré par le moteur.
