Description
Technical Parameters
Brief Introduction
Small variable speed AC electric motorsr is a very common industrial equipment, it has the advantages of small size, large power, wide speed regulating range, stable speed, reliable operation, etc., is widely used in mechanical transmission, environmental ventilation, manufacturing and other fields.
The small variable speed AC electric motors make it occupy less space when installing and using, and is convenient for handling and storage. At the same time, its power is large, can meet the needs of different types of loads, improve production efficiency and save energy. The wide speed range makes it possible to adjust the speed of the motor according to the requirements of the load, so as to achieve more accurate control. The speed is stable, the operation is more stable, the failure and damage caused by the vibration of the machine are reduced, and the service life of the machine is extended. Reliable operation, it is widely used in mechanical transmission, environmental ventilation, manufacturing and other fields, has become an indispensable key accessories.
This type AC motor has the advantages of small size, large power, wide speed regulating range, stable speed, reliable operation, etc., which provides strong support for mechanical transmission, environmental ventilation, manufacturing and other industries. We believe that with the continuous development of science and technology, small speed regulating AC motors will continue to face more good opportunities and challenges, we must be ready to meet the changes and continue to develop themselves, to contribute to the development of the industry.

Applications
Iron and steel industry is engaged in ferrous metal mineral mining and ferrous metal smelting and processing and other industrial production activities of the industrial industry, including metal iron, chromium, manganese and other mineral mining industry, iron industry, steel industry, steel processing industry, ferroalloy smelting industry, steel wire and its products industry and other subdivisions, is one of the country's important raw material industry. In addition, because the production of steel also involves non-metallic mineral extraction and products and other industrial categories, such as coking, refractory materials, carbon products, etc., these industrial categories are usually included in the scope of the steel industry.
The motors used by iron and steel enterprises have DC motors and AC motors, because many production machinery requiring speed regulation have certain requirements for electrical control systems, such as speed regulation range, dynamic response, static difference, etc. In the past, the AC motor control system could not meet these requirements, so the DC motor has been dominant, but the DC motor has a series of shortcomings. Such as the structure of the commutator and brush to increase the amount of daily maintenance, brush and commutator often produce sparks and require a better installation environment and can not be used in flammable and explosive and harsh environment places, with the same capacity AC motor than the volume and weight and moment of inertia are larger price is higher, low efficiency than AC motor 2~3%, etc. With the development of power electronics technology, microelectronics technology and the application of modern control theory, the AC motor has developed rapidly, such as SIMO made small variable speed AC electric motors, which overcome the shortcomings of the DC motor, and the speed regulation characteristics are exactly the same or even more than the DC speed regulation performance, such as the transition process is fast.
