The invention discloses an elevator safety brake. The elevator safety brake comprises a permanent magnet shell internally provided with a suspension space, a mounting seat fixed in the permanent magnet shell, a movable iron core suspended at the position, on one side of the mounting seat, in the suspension space, a brake arm arranged corresponding to one end, extending out of the permanent magnet shell, of the movable iron core, an elastic piece driving the brake arm and the movable iron core to move along the central axis of the permanent magnet shell towards the mounting seat through elastic force, a coil arranged in the suspension space of the permanent magnet shell and surrounding the periphery of the movable iron core, and a displacement sensor, wherein the coil in a power-on state drives the movable iron core and the brake arm to overcome the elastic force of the elastic piece to move in the direction away from the mounting seat; and the displacement sensor is mounted on one side, facing the movable iron core, of the mounting seat and is used for measuring the movement displacement of the movable iron core relative to the mounting seat. The displacement sensor is arranged on the mounting seat in the permanent magnet shell, so that the movement displacement of the movable iron core can be measured, and the change condition of the reciprocating movement displacement of the movable iron core can be found in time.

    本发明公开了一种电梯安全制动器,包括内部具有悬浮空间的永磁体外壳、固定在永磁体外壳内的安装座、悬浮在安装座一侧的悬浮空间内的动铁芯、与动铁芯伸出永磁体外壳的一端对应设置的制动臂、弹性力驱动制动臂和动铁芯沿永磁体外壳的中心轴线向靠近安装座的方向运动的弹性件、设置在永磁体外壳的悬浮空间内且围绕在动铁芯外周的线圈,线圈在通电状态下驱动动铁芯和制动臂克服弹性件的弹力向远离安装座的方向运动;安装在安装座朝向动铁芯的一侧的位移传感器,位移传感器用于测量动铁芯相对于安装座的运动位移量。在永磁体外壳内的安装座上设置位移传感器,可以测量达到动铁芯的运动位移量,便于及时发现动铁芯往复运动位移量的变化情况。
