Abstract:
Provided is a brake inspection device including: load torque measurement units configured to respectively measure: load torques as a motor is normally rotated and reversely rotated in a released state where an operation of a brake for holding a rotor with respect to a stator of the motor is released; and a load torque as the motor is rotationally driven in either one of a normal direction or a reverse direction in a locked state where the brake is operated; and a determination unit configured to determine a state of the brake based on the load torques measured by the load torque measurement units.
