Three-phase asynchronous motor is a kind of electromechanical equipment that converts electromagnetic energy into mechanical kinetic energy to provide production machinery to complete various fitness exercises. It is widely used in machinery and equipment, metallurgical industry, coal, crude oil, chemical plants and other industrial production industries. The vast majority of production machinery is the use of three-phase asynchronous motor as a transmission device to drag. For example, all kinds of mechanical equipment, lifting machinery, material handling equipment, electric shovel, rolling mill, centrifugal water pump, centrifugal fan and textile equipment, etc., are many three-phase asynchronous motors to drag, an intelligent processing plant must be hundreds or even tens of thousands of three-phase asynchronous motors.

With the continuous development trend of agricultural mechanization, the use of three-phase asynchronous motors in agriculture and animal husbandry is also gradually common, such as power engineering row Xiang, off, rice, crushing oil and crushing and other agricultural machinery are mostly driven by three-phase asynchronous motors.

Because of the gradual intelligence of national defense science and technology, the new scientific and technological components of various military equipment continue to improve, three-phase asynchronous motors are increasingly used in national defense science and technology and various military equipment. For example, most of the steering headlight system software for land and ship radar detection and weapons is driven by three-phase asynchronous motors.

In the transportation industry, with the continuous improvement of everyone's awareness of ecological environment protection and environmental protection and energy conservation, the development trend of electric railway, urban rail and other electric public transportation tools has attracted more and more attention. Therefore, there will also be a need for a large number of traction belt motors with quality starting, braking systems and shifting characteristics.

In shipping and air cargo, there must be many ship motors and airline motors with special requirements. In daily life, electric fans, automatic washing machines, household refrigerators, air conditioners, etc. are also driven by motors. With the continuous improvement of the level of industrial production automation technology, many operating motors with various characteristics are required as hydraulic control systems or implementation components for automation technology.

In addition, in culture and art, diagnosis and treatment and scientific research. The use of three-phase asynchronous motor is becoming more and more common. Most of the production machinery are selected three-phase asynchronous motor drag, which is due to the selection of three-phase asynchronous motor drag has a series of advantages:

1, electromagnetic energy far kneeling transportation simple economic development, simple distribution, convenient inspection side, high quality and low price

2, three-phase asynchronous motor drag than other ways of drag high efficiency. The connection between the transmission device and the dragging mechanical equipment is simple;

3. There are many forms and types of three-phase asynchronous motors, with various characteristics. It can be integrated into different production machinery, and the starting, braking system, reverse direction and speed change of three-phase asynchronous motor are easy and fast to operate, and the speed change characteristics are excellent;

4, can complete long-distance manipulation and automatic adjustment, and thus complete the processing process automation technology.
