Brushless DC motors are widely used in various application needs such as various loads, constant loads and positioning applications in industrial control, automotive, aviation, automation systems, healthcare equipment, etc.
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 has gradually become the mainstream of industrial motor development.
The research and attempts to reduce production costs and improve operating efficiency have achieved significant benefits, and major manufacturers also provide different types of motors to meet the needs of different drive systems.
At this stage, brushless DC motors are involved in industrial production such as textiles, metallurgy, printing, automated production lines, and CNC machine tools.
automotive field
In addition to the core engine, motors are also found in wipers, electric doors, automotive air conditioners, and electric windows.
With the development of the automobile industry in the direction of energy saving and environmental protection, the motors used must also meet the standards of high efficiency and low energy consumption.
The advantages of brushless DC motors, such as low noise, long life, no spark interference, and convenient centralized control, are fully in line. With the maturity of its speed regulation technology, the cost performance will become higher and higher. application will be more extensive.
Medical equipment field
In foreign countries, the use of brushless DC motors has become more common, and can be used to drive small blood pumps in artificial hearts; in China, high-speed centrifuges for high-speed surgical instruments, infrared laser modulators for thermal imagers and thermometers Both use brushless DC motors.
Home appliance field
"Inverter" technology has become very common. As a symbol of Chinese home appliances, it has gradually occupied most of the consumer market. "DC inverter" is favored by manufacturers and has gradually replaced "AC inverter".
This transformation is essentially the transition of the motors used in home appliances from induction motors to brushless DC motors and their controllers, in order to meet the requirements of energy conservation, environmental protection, low noise intelligence, and high comfort.
The development direction of brushless DC motor is the same as that of power electronics, sensors, control theory and other technologies. It is the product of the combination of various technologies, and its development depends on the innovation and progress of each technology related to it.
Office computer peripherals, electronic digital consumer goods
For example, in common printers, fax machines, copiers, hard disk drives, floppy disk drives, movie cameras, etc., there are brushless DC motors in the drive control of their main shafts and auxiliary movements.
