Brushless Motors: Making Air Purifiers Quieter and More Efficient!

Air purifiers are common household items used to clean the air in enclosed spaces. As people pay more attention to air quality, air purifiers are becoming increasingly popular as a reliable solution to remove indoor pollutants. The device module of an air purifier consists of a motor and a gearbox. Brushless DC gear motors, with their advantages of being small-sized, low-noise, and low-heat, are particularly well-suited for use in air purifiers.

Brushless DC Gear Motors for Air Purifiers

There are two types of gear motors used in air purifiers: brushed DC gear motors and brushless DC gear motors. Brushed motors use brushes to transfer electric current to the internal components. Although they are cheaper, they require regular maintenance, can overheat, and tend to be noisy. In contrast, brushless DC gear motors replace the brushes and commutator with a small circuit board that coordinates the energy transfer. Thanks to their high efficiency, low maintenance, high reliability, low rotor inertia, and low noise, brushless DC motors are gaining popularity in the smart home field.

More Powerful, Smarter, and More Efficient

The gear motors used in air purifiers need to be low-noise, low-heat, and high-efficiency. Brushless DC gear motors meet these requirements perfectly. Designed with a compact structure, brushless gear motors are available in diameters ranging from 3.4mm to 38mm. Unlike brushed DC gear motors, brushless ones do not suffer from the friction and voltage drop caused by brushes rubbing against the spinning commutator, which eliminates noise and overheating issues.

Conclusion

With the growing pursuit of a healthy lifestyle and increasing attention to indoor air quality, air purifiers have become an essential household item. Brushless DC gear motors, with their outstanding performance and reliability, provide a solid technological foundation for the efficient operation of air purifiers. As technology continues to advance and market demand grows, brushless DC gear motors will play an even bigger role in the air purifier industry, helping to create a fresher and healthier indoor environment for everyone.
