PROBLEM TO BE SOLVED: To prevent a cost increase of a vibration control system which is relatively high-priced when a servo motor is used for vibration control, and to prevent an increase of energy consumption which occurs when a control system is always in an operation state.SOLUTION: An elevator is provided with a vibration control device that includes: an acceleration meter for detecting the vibration acceleration of an elevator car; a controller that determines the control amount of a motor on the basis of the vibration acceleration when the vibration acceleration exceeds a predetermined threshold value, and determines the rotational direction of the motor on the basis of the direction of the car acceleration when the vibration acceleration exceeds the threshold value; and the motor that is driven in response to a control command including the control amount and the motor rotational direction output from the controller.SELECTED DRAWING: Figure 1

    【課題】振動制御にサーボモータを使用すると、比較的高価で制振システムとしてコスト高となってしまう。また、常に制御系を稼動状態にしておくと消費エネルギが大きくなってしまう。【解決手段】エレベータ乗りかごの振動加速度を検出する加速度計と、振動加速度が予め定められた閾値を超えた場合、振動加速度に基づいてモータの制御量を決定し、振動加速度が閾値を超えた時の乗りかご加速度の方向に基づいてモータの回転方向を決定する制御器と、制御器から出される制御量とモータの回転方向を含む制御指令により駆動されるモータと、を備えた制振装置を備える。【選択図】図1
