The invention discloses an elevator brake wear detection method and device and an elevator brake. The elevator brake comprises a fixed part with an electromagnetic piece and a moving part with a friction piece, and in a first state, the moving part is driven to move towards an elevator power device and makes contact with the elevator power device through the friction piece to provide braking force so that an elevator car can be stopped. The elevator brake abrasion detection method comprises the steps that A, the elevator brake is made to be in the first state, and an electric signal is input into the electromagnetic part to generate an electromagnetic field penetrating through an air gap between the fixed part and the moving part; b, inductance data or inductance response data of the electromagnetic part in the electromagnetic field are obtained; and C, obtaining a corresponding air gap value according to the inductance value based on a preset corresponding relation model of the inductance and the air gap of the electromagnetic part in the first state so as to determine the wear state of the friction part, or determining the wear state of the friction part according to the inductance response data.

    本发明公开了电梯制动器磨损检测方法和检测装置以及电梯制动器。电梯制动器包括:具有电磁件的固定部和具有摩擦件的运动部,并在第一状态下驱使运动部朝向电梯动力装置运动并通过摩擦件与其接触以提供制动力使电梯轿厢止停,在第二状态下由电磁件提供电磁力使摩擦件与电梯动力装置脱离接触,电梯制动器磨损检测方法包括步骤:A.使电梯制动器处于第一状态,并向电磁件输入电信号以产生穿过固定部和运动部之间空气间隙的电磁场;B.获得电磁件在电磁场下的电感数据或电感响应数据;C.基于预设的在第一状态下电磁件的电感与空气间隙的对应关系模型,根据电感值获得对应的空气间隙值以确定摩擦件的磨损状态,或根据电感响应数据确定摩擦件的磨损状态。
