Abstract: A detection method for elevator brake moment solves the problems that operation of the brake detection device in the prior art is required to be manually executed, the brake detection device is not convenient and facilitative to operate, the function is singular and the brake moment change trend and the brake wear trend cannot be reflected. In the method, by inputting stagewise torque current to the motor and determine whether the torque during rotation of a motor is within the design moment range of a brake, whether torque of the brake is enough can be determined and the brake wear trend can be analyzed according to torque recorded at each time. The method has advantages that the automatic detection is performed periodically, the functions are diversified, the detection accuracy is high, the brake moment change trend can be reflected and the brake wear trend can also be reflected.
