Application field one, office computer peripheral equipment, electronic digital consumer goods field.

This is the field where brushless DC motors are the most popular and the largest in number. For example, common printers, fax machines, photocopiers, hard disk drives, floppy disk drives, movie cameras, tape recorders, etc. in life have brushless DC motors in the drive control of their main shafts and auxiliary motions.

2Application field two, industrial control field.

In recent years, due to the large-scale research and development of brushless DC motors and the gradual maturity of technology, the distribution range of their drive systems in industrial production has also expanded, and they have gradually become the mainstream of industrial motor development. Research and attempts to reduce production costs and improve operating efficiency have achieved significant benefits. Major manufacturers also provide different types of motors to meet the needs of different drive systems. At this stage, brushless DC motors have been involved in industrial production such as textiles, metallurgy, printing, automated production lines, and CNC machine tools.

3The third application area is the field of medical equipment.

In foreign countries, the use of brushless DC motors has become more common, which can be used to drive small blood pumps in artificial hearts; in China, high-speed centrifuges, thermal imaging cameras, and infrared laser modulators for thermometers for high-speed surgical appliances Both use brushless DC motors.

4Application field four, automotive field.

According to the analysis on the market, a general family car needs 20-30 permanent magnet motors, while each luxury car needs as many as 59. In addition to the core engine, it is used in wipers, electric doors, car air conditioners, electric windows, etc. There are motors in all parts. With the development of the automobile industry in the direction of energy conservation and environmental protection, the motors used must also meet the standards of high efficiency and low energy consumption. The brushless DC motor’s low noise, long life, no spark interference, convenient centralized control and other advantages are fully in line with it. As its speed regulation technology becomes more mature, the cost performance will become higher and higher. It is used in all aspects of automobile motor drive. The application will be more extensive.

5Application field five, the field of household appliances.

In the past, “frequency conversion” technology has become very common. As a symbol of Chinese home appliances, it has gradually occupied most of the consumer market. “DC frequency conversion” has been favored by manufacturers, and there has been a shifting trend of gradually replacing “AC frequency conversion”. This transformation is essentially the transition from induction motors to brushless DC motors and their controllers for motors used in home appliances to meet the requirements of energy conservation, environmental protection, low noise, intelligence, and high comfort. The development direction of the brushless DC motor is the same as the development direction of power electronics, sensors, control theory and other technologies. It is the product of a combination of multiple technologies. Its development depends on the innovation and progress of each technology related to it.
