Application of Micro Motors for Large and Small Fans

For various ventilation equipment including handheld mini fans, desk fans, household standing fans and air purifier blowers, Huajuntong Motor offers professional power solutions with our full range of brushed and brushless external rotor motors. We customize solutions according to equipment size, air volume requirement, noise standard and budget. We provide flexible selection between brushed and brushless motors for devices ranging from compact mini products to medium and large household ventilation equipment, perfectly meeting the operating requirements of all application scenarios.

1. Mini fans & small purifiers (ultra-narrow air ducts, slim devices)

For handheld folding fans, USB mini fans and portable small purifiers with fan blade size within 80mm, which feature compact size, low voltage, low noise and light weight, Huajuntong provides power solutions of micro brushed motors and micro outer rotor brushless motors.

For cost-effective models, N20, M30 and 1220 micro brushed motors are available. They feature compact structure, sensitive start-up and controllable cost, fully meeting basic air supply needs of regular mini fans. For devices requiring premium performance, long service life and low noise, the 1413 micro outer rotor brushless motor is an ideal choice for slim purification equipment and handheld fans. Compared with brushed motors, it runs more smoothly with no carbon brush wear and greatly extended service life, perfectly suited for mini equipment with precise air ducts.

2. Desk fans & standard household purifiers (medium and small air volume equipment)

Suitable for desk circulating fans, car fans and standard household air purifiers with fan blades of 90–140mm. These devices have certain requirements for air volume, operation stability and noise level.

For cost-effective solutions, 180 and 370 brushed motors are recommended. They feature simple drive, large air volume and good compatibility with conventional centrifugal impellers. For upgraded quiet and long-lasting performance, choose 2826, 2931, 3523 and 3825 outer rotor brushless motors. With low vibration, low noise and steady rotating speed, they work well for mid-range purifiers and desk circulating fans, effectively solving unstable wind speed and excessive operating noise.

3. Medium & large household fans & high-end purifiers (12–18 inch standing fans, living room circulating fans)

Designed for mainstream large-size standing fans, whole-house circulating fans and high-end household air purifiers. These equipment require sufficient torque, steady air delivery, multi-speed adjustment and heat-resistant performance during long-hour operation.

Cost-effective units can adopt 520 and 36ZY brushed motors to meet basic high air volume requirements. High-end units are universally fitted with 4528, 4825, 5525 and 6132 outer rotor brushless motors, all proven models dedicated to household fans and purification equipment from Huajuntong. Among them, 5525 and 6132 are tailored for premium home applications, compatible with 14–18 inch standing fans and high-air-volume purifiers. They deliver excellent mute performance, stable continuous operation and great durability for long-time running, enabling optimized selection that fits actual working conditions.

4. Full-process factory strength to ensure stable mass production

To meet the supporting demands for a full range of motors used in fans and purifiers, Huajuntong relies on its modern intelligent manufacturing base to deliver full-chain support from customized sampling to mass production. We comprehensively resolve clients' key challenges in R&D implementation, quality control and delivery schedules.

Equipped with multiple automated production lines and professional testing equipment, we adopt standardized operations throughout the process to realize large-scale production of various brushed and brushless fan motors. This ensures consistent parameters and stable performance of bulk products, eliminating quality discrepancies between samples and mass-produced goods.We also support parameter customization.

We can make fine adjustments according to clients' requirements on fan blade size, air volume, noise, voltage and rotating speed to perfectly match different end products. Backed by a sound quality control system and sufficient production capacity, we steadily accept orders of all sizes with controllable lead time and comprehensive after-sales services, helping clients launch products smoothly and enhance market competitiveness.

Overall, Huajuntong can recommend cost-effective brushed motors or high-end brushless motors based on customers' product positioning, dimensions and budget. We provide tailored solutions instead of rigid model matching. From mini portable devices to medium air volume equipment, we deliver complete motor power solutions featuring high precision, stable performance and cost efficiency.
