This brake deterioration assessment device (1) has: a control unit (2) that performs control to gradually increase the value of the current supplied to a motor (21) in a state in which a brake (22) that restricts the rotation of the motor (21) is closed; a torque estimation unit (4) that estimates a brake torque value on the basis of the value of the current supplied to the motor (21); and a brakedeterioration assessment unit (7) that compares the brake torque value estimated by the torque estimation unit (4) with a reference value and assesses deterioration of the brake (22).

    制动器劣化判断装置(1)具有:控制部(2),其进行在对电动机(21)的旋转进行限制的制动器(22)闭合的状态下将向电动机(21)供给的电流的值逐渐地变大的控制;扭矩推定部(4),其基于向电动机(21)供给的电流的值对制动器扭矩的值进行推定;以及制动器劣化判断部(7),其将由扭矩推定部(4)推定出的制动器扭矩的值与基准值进行比较,对制动器(22)的劣化进行判断。
