With the development of energy-saving and environmental protection of automobiles, high-efficiency permanent magnet motors, including brushless DC motors, have a good application prospect in automobiles. In addition to being the core component of automobile drive, motor can also be used to drive automobile air conditioner, wiper, electric door airbag, electric seat and so on. The motor drive technology of automobile air conditioner is similar to that of domestic air conditioner compressor. The air-conditioning compressor driven by brushless DC motor will develop towards more energy-saving and comfortable full DC frequency conversion. Therefore, brushless DC motor will become a mainstream direction of speed regulation technology development, and will be more and more widely used in all aspects of automobile motor drive.

3. The application of brushless DC motor in household appliances
There are compressor motors in the air conditioner and refrigerator. Traditional compressor motors are usually asynchronous motors with low frequency and power factor. After adopting frequency conversion technology, the situation has been improved.
The spindle drive motors of household appliances such as VCD, DVD and CD players have gradually begun to use brushless DC motors. Other household appliances, such as electric bicycles, vacuum cleaners, mixers, hair dryers, cameras, household electric fans, etc., are gradually replacing commonly used DC motors, single-phase asynchronous motors and asynchronous motors driven by variable voltage and frequency conversion.
Brushless DC motor can not only overcome some shortcomings of traditional household motors, but also bring higher comfort to people's home life, reduce energy consumption and better realize sustainable energy development.
4. Application of Brushless DC Motor in Office Automation
Brushless DC motors have also been well applied in office equipment products, such as computer cooling fans, digital cameras, copiers, fax machines, shredders, tape recorders and LD DVD players.
5. Application in fans and pumps
At present, DC brushless motor has been successfully applied to small fans such as axial flow fan, cross flow fan and electric fan exhaust fan of household air conditioner. Due to the improvement of motor efficiency, the power consumption of small fan is obviously reduced, and the performance and quality are greatly improved.
6. Application in medical equipment
With the development of domestic medical technology and the improvement of people's living standards, a new generation of brushless DC motor drive system with low noise, wide speed regulation, small volume and light weight is urgently needed.
In short, with the emergence of new electronic technologies, new devices, new materials and new control methods, brushless motors have entered the era of Hall sensors, and the era of square waves has entered the era of sine waves. Thanks to the progress of technology, Glendale Motor has always adhered to the spirit of innovation, introduced new technologies to develop the brushless motor industry, and achieved another progress and leap in brushless motors with the most advanced Hall-free scheme, achieving low noise, high frequency and more stable performance. A new type of brushless motor with lower cost has been applied to domestic fans, industrial fans, air purifiers, exhaust fans, range hoods and so on with voltages ranging from 6V to 220V.
