PROBLEM TO BE SOLVED: To determine whether car vertical vibration is caused by torque pulsation of an electric motor or by a generation factor other than the torque pulsation when detecting the car vertical vibration due to resonance with a rope natural frequency .SOLUTION: A elevator device includes: a first pulse generator installed in an electric motor for driving a car; and a second pulse generator installed in a speed governor. The elevator device further includes a vibration detection section for detecting vertical vibration of the car due to resonance with a natural frequency of a rope coupled to the car, on the basis of detection data obtained by the first pulse generator and detection data obtained by the second pulse generator.SELECTED DRAWING: Figure 6
【課題】ロープ固有振動数との共振によるかご上下振動の検出にあたって、かご上下振動が電動機のトルク脈動に起因する振動かそれ以外の発生要因に起因する振動かの判断を可能とする。【解決手段】本発明のエレベータ装置は、乗りかごを駆動する電動機に設置された第1のパルス発生器と、調速機に設置された第2のパルス発生器と、を備えるエレベータ装置であって、第1のパルス発生器の検出データと第2のパルス発生器の検出データとに基づいて、乗りかごに連結されたロープの固有振動数との共振による乗りかごの上下振動を検出する振動検出部を備える。【選択図】 図6
