What are the applications of brushless motors in?
Everyone knows that brushless DC motors consist of a motor body and a driver, and are a typical mechatronics product. And it has the advantages of simple structure, good speed regulation performance, reliable operation, high efficiency, long service life, and convenient maintenance. But what are the applications of brushless motors in? How much does everyone know? Today, let's learn about the application fields of brushless DC motors together.
1. Brushless DC motor for automobiles
Brushless motors have strong overload capacity and good regenerative braking effect. When the car is going downhill or braking, the motor can fully enter the generator state, charge the battery, and also play an electric braking role, reducing the burden of mechanical braking. The motor has the advantages of small size, light weight, high power, and can effectively reduce weight and save space. Therefore, brushless DC motors will become a mainstream direction for the development of speed regulation technology, and will be increasingly widely used in various aspects of automotive motor drive. In addition to serving as the core component for driving cars, motors can also be used in driving car air conditioning, wipers, electric door airbags, electric seats, and other applications.
2. Brushless DC motor for aviation use
DC brushless motors have also been used to circulate oxygen in portable life support systems on the moon. Compared to brushed motors, brushless motors are better able to survive in extreme environmental conditions, thereby meeting critical task performance requirements. Due to its maintenance free operation, brushless DC motors are an ideal choice for space exploration, flight, satellites, and other fields.
3. Application of Brushless DC Motor in Household Appliances
In the field of household appliances. Previously, "frequency conversion" technology was very common, and as a symbol of Chinese household appliances, it gradually occupied most of the consumer market. "DC frequency conversion" was favored by manufacturers and has gradually replaced the trend of "AC frequency conversion". Brushless DC motors can not only overcome some of the shortcomings of traditional household motors, bringing higher comfort to people's home life, but also reduce energy consumption.
Both air conditioners and refrigerators have compressor motors. Traditional compressor motors are usually asynchronous motors with low frequency and power factor. After adopting frequency conversion technology, the situation has been improved. Brushless DC motors are gradually being used as spindle drive motors for household appliances such as VCD, DVD, and CD players. Other household appliances such as electric bicycles, vacuum cleaners, mixers, hair dryers, cameras, and home fans
Gradually adopting brushless DC motors to replace the commonly used DC motors, single-phase asynchronous motors, and variable voltage variable frequency drive asynchronous motors. This transformation is essentially the transition of electric motors used in household appliances from induction motors to brushless DC motors and their controllers, in order to meet the requirements of energy conservation, environmental protection, low intelligence, and high comfort.
4. Application of Brushless DC Motor in Office Automation Field
This is the most widely used and numerous field of brushless DC motors. For example, office equipment products such as fans, digital cameras, copiers, fax machines, shredders, hard drives, floppy drives, tape recorders, and LD DVD players commonly used for computer cooling in daily life have also been well applied.
5. Application on fans and water pumps
At present, brushless DC motors have been successfully used in small fans such as axial flow fans, cross flow fans, electric fans, and exhaust fans for household air conditioning. Due to the improvement of motor efficiency, the power consumption of small fans has significantly decreased, and their performance and quality have been greatly improved.
6. Application in medical devices
With the development of domestic medical technology and the improvement of people's living standards, there is an urgent need for a new generation of brushless DC motor drive systems with low noise, wide speed range, small size, and light weight. In foreign countries, the use of brushless DC motors has become quite common and can be used to drive small blood pumps in artificial hearts; In China, brushless DC motors are used in high-speed centrifuges, thermal imagers, and infrared laser modulators for thermometers used in surgeries.
