1. Three-phase asynchronous motor for motor operation.

2. The speed of the rotor of the three-phase asynchronous motor is lower than the speed of the rotating magnetic field. There will be relative movement between the rotor winding and the magnetic field. However, electromotive force and current are generated, which interact with the magnetic field to generate electromagnetic torque and realize energy conversion.

Compared with its single-phase asynchronous motor, three-phase asynchronous motor has good running performance, which can save a variety of materials.

4, in strict accordance with the different rotor structure, three-phase asynchronous motor can be divided into cage type such as winding type five.

5. Cage rotor asynchronous motors have simple structure, reliable operation, light weight and low price, and have been widely used. The primary disadvantage of the latter is difficulty in speed regulation.

6. The stator of the rotor of the winding old three-phase asynchronous motor is not only set up as a three-phase winding, but also uses slip rings and brushes to connect with non-internal and external rheostats.
