Description

technical field [0001] The invention relates to an online automatic test device and method for static braking torque of an elevator traction machine, which belongs to the technical field of elevator traction machine manufacturing and can be used for static braking of elevator traction machines or similar transmission mechanisms with braking requirements. Online test of torque. Background technique [0002] In the field of elevator traction machine production and manufacturing, the static braking of the main drive motor refers to preventing the car from moving due to the unequal tension of the wire ropes on both sides of the traction sheave when the car is at rest. One of the important safety technical indicators of the machine. In the process of elevator traction machine production and manufacturing, before the finished product leaves the factory, the static braking torque test is a necessary part of controlling product quality, and accurate data must be used to determine w...
