Products details

High-Speed Brushless Motor for Heavy-Duty Fan Systems

The BLW6121-XMD02 high-speed brushless motor operates on a 36V DC platform with 3-phase 10-pole external drive technology. It delivers 65–70W output at 2100±5% RPM, making it a powerful solution for large-scale air movement systems like industrial floor fans, tower fans, and air purifiers.

With an integrated industrial fan motor structure and ABS fan blade compatibility, this motor is rated for 270g load capacity. The open rotor design and ball bearing assembly promote stable airflow with minimal mechanical resistance. Paired with VSP speed control, it enables flexible RPM adjustments across varied operational demands.


Low Noise Motor Operation & Longevity

This low noise motor is optimized to produce ≤45 dB at 0.5 meters under rated voltage and no-load conditions. The inclusion of B-class insulation (≥10MΩ resistance, 600V AC strength) and lock protection (auto-shutdown in 1.5–3.0 seconds) safeguards motor integrity and enhances its service life.

Heat-treated rare earth magnets ensure a magnetic decay rate ≤5% even after prolonged operation at 130°C, securing torque stability and long-term durability. The motor is built for 15,000+ hours of reliable function under rated conditions.


 EMC Compliance, Thermal Management & Testing

Built for industrial environments, this high-speed brushless motor integrates:

  • Thermal shielding with 26×23×15mm aluminum heat sinks

  • High-current MOSFETs rated at ≥12A

  • EMC leakage flux ≤0.6mT at 1cm from rotor center

The product passes rigorous environmental validations, including -40°C to 70°C thermal shock, 72-hour continuous load tests, and 85% RH humidity cycling, ensuring durability in demanding climates.


 Custom Configurations & Certified Quality

Our motor supports high-volume OEM production with fast turnaround times. Custom options include:

  • 62cm PVC-sheathed wire with XHB2.54-3P terminals

  • Shaft material variants: S45C (anti-rust), SUS303, or SUS416

  • ISO 9001, IATF 16949, and EMC certifications

Precision stamping and automated assembly ensure ±0.01mm tolerance—key for applications like medical devices, smart fans, air treatment systems, and mobile air conditioners.

Applications

Floor fans (with blades under 16 inches), table fans, circulating fans, tower fans, mobile air conditioners, ice makers, atomizers, oxygen generators, air purifiers
