VIBRATION DAMPER FOR ELEVATOR LINEAR PROPULSION SYSTEM

摘要

An elevator system may include a stationary support structure defining a hoistway; a car disposed in the hoistway; a linear propulsion assembly for applying a force to the car, the assembly including a first rail engaged to one of the support structure and the car, a plurality of magnets mounted to the first rail, a second rail co-extending with and spaced laterally from the first rail and engaged to the other of the support structure and the car, and a plurality of electric coils mounted to the second rail; and, a damper engaged to at least one of the first and second rails for dissipating vibration.
