There are so many application fields for brushless DC motors.
Brushless DC motor consists of a motor body and a driver, and is a typical electromechanical integrated product. Due to its many advantages such as small size, good performance, low noise, high efficiency, and long lifespan, it is widely used. Today, Jinyuan Electromechanical will introduce four important application areas to you.
1. Precision electronic equipment and appliances
Due to the fact that most electronic devices are powered by DC power supply and require motors to have characteristics such as speed regulation, stable speed, and positioning control. Therefore, most precision equipment currently uses brushless DC motor drive control. Such as computer hard and floppy disk drivers, laser typewriter prism drivers, camera drum drivers, CD player drivers, medical diagnostic CT machines, therapeutic high-speed dental drills, satellite solar panel drivers, instrument ventilation fans, etc. The application in this field is gradually being promoted, replacing brushed motors.
2. Industrial automation equipment
At present, high-end CNC machining equipment has been applied, and there is a trend to replace traditional DC and AC motors. In addition, it has also been promoted and applied in some industrial processing equipment, such as industrial sewing machines, light printing machinery, food processing machinery, etc. It is worth paying close attention to the potential practicality of industrial robot drive control. Due to the requirements for speed, torque, and positioning control in this application, brushless motors are the preferred variety. Currently, there are more than one million robots of various types worldwide, and the demand for brushless DC motors is growing at a rate of over 20% per year.
3. Automobiles and electric vehicles
Modern cars are developing towards luxury models, with a high degree of automation and the use of numerous plastic motors, among which brushless DC motors are adopted in many difficult to maintain components. In addition, as a pollution-free future transportation tool, electric vehicles have received attention from the industrial sectors of various countries, and are currently increasing investment and development. Brushless DC motors are the most ideal power source, first used in electric motorcycles or electric assisted vehicles, and have gradually entered mass production. It is estimated that electric vehicles will also be widely popularized in 3-5 years.
4. Modern household appliances
Many years ago, General Electric of the United States launched a so-called intelligent electric motor, which attracted international attention. In fact, this motor is a brushless DC motor controlled by a microprocessor. Due to its wide speed range, low noise, high efficiency, and the ability to achieve certain "intelligent" operation, this type of motor was favored by designers in the household appliance industry when it was first introduced. Later, it was gradually applied in household appliances such as washing machines, air conditioners, and refrigerators, enabling these appliances to achieve energy-saving, multifunctional, and automatic control, such as timing, temperature control, natural adjustment, and work according to software programs.
In recent years, brushless DC motors have been applied in various household appliances to improve their automation level, such as air conditioners that automatically adjust temperature according to room temperature, washing machines that can choose different types of clothes, and refrigerators that automatically select freezing temperature based on refrigerated items. There is a trend of replacing AC motors in household appliances. At present, such products have been developed in China and will soon be launched on the market. The application prospects of brushless DC motors in household appliances have greatly stimulated the development and research of brushless motors.
