Description

Technical Field

[0001] The utility model relates to the technical field of motor processing, in particular to a compact and efficient variable frequency speed regulating three-phase asynchronous motor processing fixing device. Background Art

[0002] The three-phase asynchronous motor, which is operated by an electric motor, has a rotor whose speed is lower than that of the rotating magnetic field. The rotor winding generates electromotive force and current due to the relative motion between the rotor winding and the magnetic field, and generates electromagnetic torque by interacting with the magnetic field to achieve energy conversion. Compared with single-phase asynchronous motors, three-phase asynchronous motors have good operating performance and can save various materials. According to the different rotor structures, three-phase asynchronous motors can be divided into cage type and winding type. The cage rotor asynchronous motor has a simple structure, reliable operation, light weight, and low price, and has been widely used. Its main disadvantage is that it is difficult to adjust the speed. The rotor of the winding three-phase asynchronous motor is also equipped with a three-phase winding like the stator and is connected to an external rheostat through slip rings and brushes. Adjusting the rheostat resistance can improve the starting performance of the motor and adjust the speed of the motor.

[0003] At present, when processing three-phase asynchronous motors, the three-phase asynchronous motors need to be fixed. In traditional devices, bolts are generally used to fix the motors, and then processing is performed. However, during the processing, the side of the three-phase asynchronous motor placed on the working surface cannot be processed, and the bolts need to be removed, turned over and fixed, and then processed. This is repeated, resulting in low work efficiency. Therefore, in order to solve the problem of repeated turning over and fixing during the processing process, a compact and efficient variable frequency speed regulation three-phase asynchronous motor processing fixing device is proposed.
