The present invention relates to braking torque detection for an elevator brake (140) and belongs to the technical field of elevators. A braking torque detection method for an elevator brake (140) according to the present invention comprises the following steps (S320,S410):a drive motor (130) outputting a first detection torque (T1,T2) for a first brake torque inspection; the drive motor (130) stopping output of the detection torque (T1,T2) 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 (130) outputting a second detection torque (T1,T2) for the second brake torque inspection. The present invention can avoid overheating of a frequency converter (120) in a continuous braking torque detection process and achieves good braking torque detection accuracy.
