Problems solved by technology

[0002] Three-phase asynchronous motor is a kind of induction motor. It is a type of motor powered by 380V three-phase AC current at the same time. Since the rotor and stator of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is Slip, so it is called a three-phase asynchronous motor; the speed of the rotor of the 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 interacts with the magnetic field to generate electromagnetic torque , to realize energy transformation; the rotating shaft of the existing motor is generally connected with the front and rear end covers through the rotating bearing, so as to realize the fixing of the rotating shaft, and the rotating shaft with such a connection structure will shake to a certain extent due to wear after a period of use , and the installation of the rotating shaft is relatively 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 three-phase asynchronous motor. The motor comprises an outer shell, a front end cover, a rear end cover, a rotating shaft, a cage-shaped rotor, a stator, and a positioning assembly. According to the invention, the transmission performance of the whole rotating shaft is more stable through an elastically-abutting mounting structure; and the rotating shaft is very convenient to mount and dismount.

Description

technical field [0001] The invention relates to a three-phase asynchronous motor. Background technique [0002] Three-phase asynchronous motor is a kind of induction motor, which is a type of motor powered by 380V three-phase AC current at the same time. Since the rotor and stator rotating magnetic field of the three-phase asynchronous motor rotate in the same direction and different speeds, there The slip rate, so it is called a three-phase asynchronous motor; the rotational speed of the rotor of the three-phase asynchronous motor is lower than the rotational speed 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 interacts with the magnetic field to generate electromagnetic torque , to achieve energy conversion; the rotating shaft of the existing motor is generally connected with the front and rear end covers through the rotating connection of the bear...
