Abstract:
An elevator comprising:a pair of rails vertically arranged on side walls in a hoistway; an elevator car including a cage which runs in the hoistway along the pair of rails; and a plurality of guide devices for guiding the elevator car along the pair of rails, the plurality of guide devices contacting sides of the pair of rails, wherein each of the plurality of guide devices includes: a guide lever pivotally attached to a support member fixed to the elevator car, so that the guide lever may be driven in a plane; a guide element for guiding the elevator car along the rail, the guide element being attached to the guide lever and contacting one of the rails; and an actuator device having a stationary actuator part fixed to the support member, and a moving actuator part fixed to the guide lever and driven in the plane, wherein one of the moving actuator part and the stationary actuator part is a magnet generating a magnetic field crossing a drive direction of the moving actuator part, the other of the moving actuator part and the stationary actuator part is a coil, wherein a Lorentz force is generated by interaction of the magnetic field and supplying of an electric current to the coil when the elevator car is vibrating, so that the guide lever is driven by the Lorentz force to suppress vibration of the elevator car.
