The rotor speed of three-phase asynchronous motor is lower than the speed of rotating magnetic field, and the rotor winding generates electromotive force and current due to the relative movement between the rotor winding and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque to realize energy conversion.
Compared with single-phase asynchronous motors, three-phase asynchronous motors have better operating performance and can save various materials. According to the different rotor structures, three-phase asynchronous motors can be divided into cage type and winding type. The asynchronous motor with cage rotor has a simple structure, reliable operation, light weight, and low price, which has been widely used. Its main drawback is the difficulty in speed regulation. The rotor and stator of a wound three-phase asynchronous motor are also equipped with three-phase windings and connected to an external rheostat through slip rings, brushes. Adjusting the resistance of the rheostat can improve the starting performance of the motor and adjust the speed of the motor.
A three-phase asynchronous motor consists of two basic parts: a fixed stator and a rotating rotor. The rotor is installed in the stator cavity and supported on two end covers by bearings.
Three phase asynchronous motor is a commonly used motor, widely used in various industrial and civil fields. Its main uses include:
1. Industrial production: Three-phase asynchronous motors can be used for various machines and equipment in industrial production, such as compressors, pumps, fans, conveyors, grinders, cutting machines, etc.
2. Transportation: Three-phase asynchronous motors can be used for various transportation tools, such as electric cars, electric trains, electric boats, etc.
3. Agricultural production: Three-phase asynchronous motors can be used for various machines and equipment in agricultural production, such as irrigation equipment, harvesters, threshers, mixers, etc.
4. Household and commercial use: Three-phase asynchronous motors can be used for various electrical appliances and equipment in household and commercial fields, such as air conditioners, refrigerators, washing machines, vacuum cleaners, electric fans, etc.
