The present invention relates to braking torque detection for an elevator brake and belongs to the technical field of elevators. A braking torque detection method for an elevator brake according to the present invention comprises the following steps: a drive motor outputting a first detection torque for a first brake torque inspection; the drive motor stopping output of the detection torque in intermittent time periods when it is determined that a second brake torque inspection is required according to a result of the first brake torque inspection; and the drive motor outputting a second detection torque for the second brake torque inspection. The present invention can avoid overheating of a frequency converter in a continuous braking torque detection process and achieves good braking torque detection accuracy.
