Brushless DC Motor Applications

Application field 1, office computer peripherals, electronic digital consumer goods field.
This is the most popular brushless DC motor, the largest number of areas. For example, common printers, fax machines, photocopiers, hard drives, floppy disk drives, movie cameras, tape recorders, etc., have brushless DC motors in the drive control of their spindles and affiliated movements.
Application field two, industrial control field.
In recent years, due to the large-scale research and development of brushless DC motor and the gradual maturity of technology, the distribution range of its drive system in industrial production has also expanded, and it has gradually become the mainstream of industrial electric motor development. Research and attempts to reduce production costs and improve operating efficiency have achieved significant benefits, and major manufacturers also offer different types of motors to meet the needs of different drive systems. At present, in textile, metallurgy, printing, automatic production lines, CNC machine tools and other industrial production, brushless DC motors are involved.
Application field 3, medical equipment field.
In foreign countries, the use of brushless DC motor has been more common, can be used to drive the artificial heart in the small blood pump; In China, brushless DC motors are used in high-speed centrifuges of high-speed surgical instruments, infrared laser modulators of thermal imagers and thermometers.
Application field four, automotive field.
According to the analysis on the market, the general family car needs 20-30 permanent magnet motors, and each luxury car needs 59, in addition to the core engine, in the wiper, electric doors, car air conditioning, electric Windows and other parts of the motor figure. With the development of the automotive 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 advantages of brushless DC motor such as low noise, long life, no spark interference, convenient centralized control are fully in line with the increasing maturity of its speed regulation technology, the cost performance will be higher and higher, and its application in all aspects of automotive motor drive will be more extensive.
Application field five, the field of household appliances.
"Frequency conversion" technology has been very common, as a symbol of China's home appliances gradually occupied most of the consumer market, "DC frequency conversion" is favored by manufacturers, has gradually replaced the "AC frequency conversion" change trend. This change is essentially the transition of the motor used in home appliances from induction motor to brushless DC motor and its controller, in order to achieve the requirements of energy saving, environmental protection, low noise intelligence and high comfort. The development direction of brushless DC motor is the same as the development direction of power electronics, sensors, control theory and other technologies, it is the product of the combination of a variety of technologies, and its development depends on the innovation and progress of each technology related to it.
