Description

Stator framework of three-phase asynchronous motor

Technical Field

The utility model relates to the field of three-phase asynchronous motors, in particular to a stator framework of a three-phase asynchronous motor.

Background

The three-phase asynchronous motor is one kind of induction motor and is a motor powered by 380V three-phase AC current (120 deg. phase difference), and the rotor and stator of the three-phase asynchronous motor rotate in the same direction and different rotation speeds and have slip ratio, so that the motor is called a three-phase asynchronous motor. The rotating speed of the rotor of the three-phase asynchronous motor is lower than that of the rotating magnetic field, the rotor winding generates electromotive force and current due to relative motion between the rotor winding and the magnetic field, and electromagnetic torque is generated by interaction between the rotor winding and the magnetic field, so that energy conversion is realized. The stator is arranged in the three-phase asynchronous motor.

The stator is the stationary part of the motor or generator. The stator consists of a stator core, a stator winding and a stand. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force in the rotating magnetic field to generate (output) current.

The stator framework of the three-phase asynchronous motor in the current market is technically to be further improved, most of the stator framework of the three-phase asynchronous motor in the current market is integrally formed, and once a certain coil is damaged, the maintenance is very inconvenient, time and labor are wasted, and the motor possibly needs to be purchased again, so that financial resources are consumed. Therefore, it is necessary to invent a stator frame of a three-phase asynchronous motor to solve the above problems.
