Specifically, in order to achieve effective connection between the motor shaft and the driven shaft, a special connection structure such as a coupling is generally required. In the assembly process, workers need to accurately measure and calibrate parameters such as positions, sizes and the like of a motor shaft and a driven shaft, and the two parameters can be accurately butted. Then, the coupling is carefully installed on the motor shaft and the driven shaft with a wing, and a careful fastening operation is performed to prevent a loosening phenomenon from occurring during a subsequent operation. The whole assembly process not only needs professional technical knowledge and rich operation experience, but also needs a great deal of time and energy, and the assembly failure can be caused by the error of any link, and the adjustment and the installation are needed again. Furthermore, after a long period of use, the motor apparatus inevitably suffers from wear and aging of its internal components. The problem of coaxiality between the rotor and the motor shaft is particularly remarkable. Due to various forces and vibrations during operation, the relative position between the rotor and the motor shaft may be shifted, resulting in reduced coaxiality. Once this occurs, the operation stability of the apparatus is seriously affected, and problems such as vibration, noise increase, etc. are generated, and even malfunction of the apparatus may be caused. And adjusting the coaxiality between the rotor and the motor shaft is not easy, and professional detection equipment and complex adjustment process are required. The worker needs to detect the coaxiality by using a precise measuring instrument, determine the direction and the degree of the offset, and then finely adjust the rotor or the motor shaft according to the detection result.
