Selection of Air Purifier Motor.
The core secret behind why high-end air purifiers can achieve high air volume yet remain so quiet is a tailor-made brushless motor. Silicon based power collaborates deeply with multiple industry brands to analyze the selection logic of air purifier motors and share how BS5620 motors can help customers stand out in the competition.
1、 Accurate matching: Three core components for selecting air purifier motors
Unlike ordinary applications, air purifiers have strict requirements for motor wind pressure, noise, and lifespan.
High air volume and wind pressure - the source of power
Need motor driven fan blades to quickly penetrate high resistance structures such as HEPA filters. Our motor provides a strong torque of 10-150mNm, ensuring sufficient wind pressure output even when facing high-density filters within a power range of 1-80W, maintaining a stable CADR value (clean air output ratio).
Silence and Stability - The Key to User Experience
The motor noise directly determines the user experience of the product. We use electromagnetic optimization and precision dynamic balance correction to ensure that the motor can operate smoothly in a wide speed range of 1000-8000 revolutions per minute, greatly reducing high-frequency whistling. According to customer testing, under moderate air volume, the noise can be controlled below 25 decibels, almost as quiet as a whisper.
Size, voltage, and lifespan - assurance of integration and reliability
The diameter of 48-60mm is perfectly compatible with the air duct structure of mainstream tower and box purifiers. The wide voltage design of 5-24V is compatible with both DC power supply and lithium battery power supply solutions, meeting different market demands. At the same time, we use high-quality ball bearings and high-temperature resistant magnetic materials to ensure that the motor can easily exceed 30000 hours of service life under long-term uninterrupted operation, truly achieving a one-time solution.
2、 Successful case: AF60 motor helps customers create a popular "Silent King" product
Customer dilemma: A well-known home appliance brand plans to launch a new product that focuses on "deep purification of bedrooms". The core demand is to provide sufficient air flow in the highest gear while achieving extreme quietness in the middle and low gears, without affecting sleep.
Solution: We have customized a BM5620 brushless motor (diameter 60mm, power 25W) for it. This motor fully utilizes the advantages of a large-sized rotor, and can output the required air volume for customers at a medium speed of 1500 revolutions per minute, perfectly avoiding the noise peak caused by high-speed rotation.
Performance and Customer Revenue:
Silent breakthrough: In sleep mode (about 1200 revolutions per minute), the overall noise of the machine is only 22 decibels, becoming the recognized "Silent King" in the market and forming an overwhelming reputation advantage.
Energy efficiency improvement: The wide voltage design enables the product to easily adapt to voltage standards in different regions around the world, reducing the additional cost of developing multiple power versions for customers.
Reliability verification: After continuous aging testing for up to 3 months, the motor performance has not deteriorated at all, winning the high trust of the customer's quality department.
Market achievements: After the air purifier equipped with AF60 motor was launched, it quickly became the best-selling sub category on e-commerce platforms with its core selling point of "ultimate quietness under high air volume".
