Three-phase asynchronous motor manufacture with high quality and good price


  1. The rotation speed of the rotor of the three-phase asynchronous motor is lower than the rotation speed of the rotating magnetic field, and the rotor winding generates electromotive force and current due to the relative motion between the magnetic field and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque to realize energy conversion.


  1. Compared with single-phase asynchronous motors, three-phase asynchronous motors have good running performance and can save various materials.

  1. According to the rotor structure, three-phase asynchronous motors can be divided into two types: cage type and winding type. The asynchronous motor of the cage rotor has simple structure, reliable operation, light weight and low price, and has been widely used. The main disadvantage is that the speed regulation is difficult.


  1. The rotor of the wound-type three-phase asynchronous motor is also provided with a three-phase winding like a stator and is connected to an external varistor through a slip ring and a brush. Adjusting the varistor resistance improves the starting performance of the motor and regulates the speed of the motor.


  1. When the three-phase stator windings of the motor (each phase difference of 120 degrees electrical angle), after entering the three-phase symmetrical alternating current, a rotating magnetic field is generated, which rotates the rotor windings to generate an induced current in the rotor windings (the rotor windings are closed) Path), the current-carrying rotor conductor generates electromagnetic force under the rotating magnetic field of the stator, thereby forming electromagnetic torque on the motor shaft, driving the motor to rotate, and the motor rotating direction is the same as the rotating magnetic field.

6.The three-phase asynchronous motor consists of two basic parts, a fixed stator and a rotating rotor. The rotor is mounted in the inner cavity of the stator and supported on the two end caps by means of bearings.
