Three-phase asynchronous motor convenient to install

Abstract

The invention discloses a three-phase asynchronous motor convenient to install. The three-phase asynchronous motor comprises an outer shell, a front end cover, a rear end cover, a rotating shaft, a cage type rotor, a stator, a positioning assembly and a guide fine adjustment mechanism. The guide fine adjustment mechanism is additionally arranged. Through rotation of the threaded sleeve, the movable screw rod is driven to move in the rotary threaded sleeve. Meanwhile, the movable guide rod is clamped in a guide groove of the positioning cylinder through a guide block in a sliding manner. In this way, the whole positioning assembly is driven to be finely adjusted along the axial position of the rotating shaft, so that the abutting position of the abutting arc-shaped plate is finely adjustedin the axial direction, the abutting arc-shaped plate is matched with the annular abutting groove in the outer side of the periphery of the rotating shaft in position, and use is more flexible.

Description

technical field [0001] The invention relates to a conveniently installed three-phase asynchronous motor. Background technique [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. Because the rotor and stator of the conveniently installed three-phase asynchronous motor are formed in the same direction and at different speeds Rotation, there is a slip, so it is called a convenient three-phase asynchronous motor; the speed of the rotor of the convenient three-phase asynchronous motor is lower than that 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 rota...

[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. Because the rotor and stator of the conveniently installed three-phase asynchronous motor are formed in the same direction and at different speeds Rotation, there is a slip, so it is called a convenient three-phase asynchronous motor; the speed of the rotor of the convenient three-phase asynchronous motor is lower than that 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
