PROBLEM TO BE SOLVED: To provide an electromagnetic brake device, a hoist and an elevator capable of achieving improvement in diagnostic accuracy of an electromagnetic drive part.SOLUTION: An electromagnetic brake device 10 includes an electromagnetic drive part 11 and a diagnostic part 200. The diagnostic part 200 includes a normal state storage part 213, current state acquisition parts 209, 210, signal acquisition parts 201, 202 and a determination device 207. The normal state storage part 213 stores a state of cores 23, 24 with respect to a housing 21 in a state where the electromagnetic drive part 11 is in a normal state. The current state acquisition parts 209, 210 acquire the state of the cores 23, 24 with respect to the housing 21 at diagnostic time. The determination device 207 determines whether the state of the electromagnetic drive part 11 is normal or not based on the information about the current state of the cores 23, 24, the information about the normal state of the cores and a current signal.SELECTED DRAWING: Figure 5

    【課題】電磁駆動部の診断精度の向上を図ることができる電磁ブレーキ装置、巻上機及びエレベータを提供する。【解決手段】電磁ブレーキ装置10は、電磁駆動部11と、診断部200と、を備えている。診断部200は、正常状態保存部213と、現在状態取得部209,210と、信号取得部201,202と、判定器207とを備えている。正常状態保存部213は、電磁駆動部11が正常な状態におけるハウジング21に対するコア23,24の状態を保存する。現在状態取得部209、210は、診断時におけるハウジング21に対するコア23,24の状態を取得する。判定器207は、コア23,24の現在の状態の情報と、コアの正常状態の情報と、電流信号に基づいて電磁駆動部11の状態が正常か否かを判定する。【選択図】図5
