The invention discloses a braking force detection method for elevator motor brakes. When an elevator is started or stopped, an elevator control system controls at least one brake needing to be detected in a brake set to be turned on or turned off; meanwhile, the displacement of an elevator car during this period is detected, and whether braking force of the brake needing to be detected is sufficient or not is judged according to the displacement. By means of the braking force detection method, additional detection is not needed when the elevator is in a non-running state, brake force insufficiency of the brakes can be detected in time, and safety accidents are avoided.
