Application of Brushless Motor in Household Air Purifiers

Smart home, lazy life. We are constantly pursuing a comfortable life to live a pleasant and healthy life. Whether it's lazy sofas, smart curtains, sweeping robots, smart door locks, air purifiers, etc., all are designed to help us live a better and healthier life.

For a high-performance air purifier, it needs to have adjustable speed settings to ensure air circulation and ventilation. In sleep mode, the noise must be less than 40dB, and normally below 30dB. This requires a motor with high speed, long service life, low noise, adjustable speed, and overvoltage protection.

Outer rotor brushless motors can be equipped with a built-in driver board and integrated drive circuit, enabling independent speed adjustment across different gears. The speed can be regulated according to usage scenarios such as living room, bedroom, and sleep mode. Based on the external rotation principle, outer rotor brushless motors maintain high speed while keeping noise at 20-60dB. With sound insulation materials, the noise can be reduced to 20-40dB. Meanwhile, external rotation minimizes material wear, ensuring a service life of more than 2000 hours.

Huajuntong Motor specializes in the R&D and production of motors for smart homes. For air purifiers, we offer the 6132 outer rotor brushless motor, which can be applied to backward-curved centrifugal fans. It features optimized wind pressure design specifically for purifiers and is compatible with air duct systems. The specific parameters are as follows:

*Motor parameters are for reference only. Performance requirements vary for each air purifier and can be customized according to your needs.

Outer rotor brushless motors are being adopted by more and more brands for air purifiers, and their market share in future air purifiers will continue to grow. If you are developing an air purifier and are unsure which motor to use, you can choose this 6132 brushless motor, which is already widely used in the mature market.
