Problems solved by technology

[0002] Three-phase asynchronous motor is a kind of induction motor. It is a type of motor that is powered by 380V three-phase AC current at the same time. Due to the high stability of the three-phase asynchronous motor, the rotor and the stator rotate in the same direction and rotate at different speeds. Rotation, there is a slip, so it is called a high-stability three-phase asynchronous motor; the speed of the rotor of the high-stability three-phase asynchronous motor is lower than the speed of the rotating magnetic field, and the rotor winding generates electromotive force and current due to the relative motion between the rotor winding and the magnetic field. And interact with the magnetic field to generate electromagnetic torque to realize energy conversion; the rotating shaft of the existing motor is generally connected to the front and rear end covers through the rotating bearing to realize the fixing of the rotating shaft. After a while, there will be some shaking due to wear, and the installation of the rotating shaft is cumbersome, and the bearings on the rotating shaft and the front and rear end covers are generally fixed by screws, so once the screws are rusted during disassembly, it will increase the difficulty of disassembly and maintenance

Abstract

The invention discloses a high-stability three-phase asynchronous motor. The motor comprises an outer shell, a front end cover, a rear end cover, a rotating shaft, a cage rotor, a stator and a positioning assembly. According to the invention, when an annular elastic body abuts against an arc-shaped plate, due to the fact that a clamping ring body still keeps a clamping structure through sliding ofa sliding clamping rod on a clamping sliding groove of an internal thread cylinder, the annular elastic body can obtain a guiding limiting effect when abutting against the arc-shaped plate; and therefore, the annular elastic body is more stable in the radial direction when abutting against the arc-shaped plate, shaking is avoided, and a structure is more stable.
