A new control device to suppress horizontal vibration in an elevator cabin, mainly caused by irregularity of a guide rail, is presented. The proposed control device consists of two rotary electric motors with eccentric masses. The one motor produces torque to rotate the eccentric mass according to the command signal from the controller, while the other motor rotates the mass to terminate the unwanted vertical force. The performance of the proposed system is examined through the numerical simulations considering the nonlinear characteristics of the rotating masses and the experiments with a miniature elevator cabin carrying the proposed actuator. The results indicate the proposed control device reduces the vibration without producing the unwanted vertical vibration.
