Induction motors are mainly used as motors. It is the most widely used and the largest quantity of motor in the industrial and agricultural production and the national economy departments. Metal cutting machine tools, rolling equipment, blowers, shredders, pumps, oil pumps, light machinery, textile machinery, mining machinery, etc., most of them are asynchronous motor drive. In people's daily life, the application of asynchronous motor is also more and more widespread, such as electric fans, washing machines, refrigerators, air conditioners and other household appliances, the use of single-phase induction motors. In electric traction, most of the traction motors are asynchronous motors, and their power consumption accounts for about 60% of the total power load.

Asynchronous motor is widely used because of its simple structure, convenient operation, reliable operation, high efficiency, easy manufacture, low cost and so on.

The speed of asynchronous motor itself is poor, and in the case of requiring a wider range of smooth speed regulation, the general use of DC motor. In the past ten or twenty years, the asynchronous motor AC speed regulation system based on power electronic devices and microcomputers has improved the speed regulating performance of asynchronous motors, so it is used more widely.

When the asynchronous motor is running, it must absorb reactive power from the grid, which will make the power factor of the grid worse. Since the power factor of the network can be compensated in other ways, this does not prevent the widespread use of asynchronous motors.
