[0002] The three-phase asynchronous motor is a type of electric motor that is powered by a 380V three-phase AC power supply (phase difference of 120 degrees). The rotor and stator rotating magnetic fields of the three-phase asynchronous motor rotate in the same direction and at different speeds, and there is a slip rate. The three-phase asynchronous motor has high power and is mainly made into large motors. The three-phase asynchronous motor is generally used in large industrial equipment with a three-phase power supply.

[0003] 1. When installing and fixing the existing three-phase asynchronous motor, one person is required to straighten the three-phase asynchronous motor, and another person is required to fix the three-phase asynchronous motor with bolts. The fixing process is relatively cumbersome and requires cooperation of multiple people, which is inconvenient for installation;

[0004] 2. After the three-phase asynchronous motor is installed and fixed, it is necessary to adjust the position of the three-phase asynchronous motor to tighten the transmission belt between the three-phase asynchronous motor and the equipment. During the adjustment, the three-phase asynchronous motor needs to be loosened and adjusted little by little. The adjustment process needs to prevent the three-phase asynchronous motor from deflecting, and the adjustment process is relatively troublesome. Summary of the invention
