Problems solved by technology
The damper of the air-conditioning box will not close properly, causing air leakage or failing to reach the predetermined damper opening, which will affect the comfort of the air-conditioning system;
[0005] In the past, the measurement system of the torque output characteristics of the stepping motor of the automobile air conditioner is to fix the stepping motor under test on the load machine with the required size of the simulated characteristic torque, and test whether it meets the requirements according to the definition of its characteristic torque parameters or manually draw the characteristic torque curve. To measure specific parameter values, it is necessary to manually repeat the test many times, which is inefficient, and because the simulated load needs to be verified with a standard torque meter afterwards, the torque value in the non-real-time state environment results in low measurement accuracy and cannot Realize production batch measurement
