Three phase asynchronous motor three phase asynchronous motor selected manufacturers direct selling Kejin moto

  Three phase asynchronous motor is a kind of induction motor, which is powered by 380V three-phase AC (phase difference is 120 degrees) at the same time
Because the rotating magnetic field direction of rotor and stator of three-phase asynchronous motor is the same and the speed is different, there is slip, so it is called three-phase asynchronous motor
The rotor speed of three-phase asynchronous motor is lower than that of rotating magnetic field
The rotor winding generates electromotive force and current due to the relative movement with the magnetic field, and interacts with the magnetic field to produce electromagnetic torque

 
  Compared with single-phase asynchronous motor, three-phase asynchronous motor has better operation performance and can save all kinds of materials
According to different rotor structures, three-phase asynchronous motors can be divided into cage type and winding type
Cage induction motor is widely used because of its simple structure, reliable operation, light weight and low price
Its main disadvantage is the difficulty of speed regulation
The rotor and stator of wound three-phase asynchronous motor are also equipped with three-phase windings, which are connected with external rheostat through slip ring and brush
Adjusting the resistance of the rheostat can change the starting performance of the motor and adjust the speed of the motor
