Vibration damping apparatus for elevator system

摘要

A vibration damping apparatus for an elevator system capable of reducing vibrations of an elevator car in the horizontal direction while preventing friction from occurring in driving mechanisms of an actuators. The apparatus includes magnetic actuators (72a, 72b) mounted fixedly on one of lower surface of a floor of an elevator car (1) or a bottom member of a car supporting frame (2) and corresponding magnetic pole members (73a, 73b) mounted on the other one. Vibration sensors (58, 59) are installed on the car floor or the bottom member of the car supporting frame (2). Detection signals of the sensors (58, 59) are inputted to a controller (61) which responds thereto by controlling driving of the magnetic actuators (72a, 72b) so that vibration of the elevator car (1) can be reduced.
