Client Background & Challenges
Our client is a leading consumer electronics brand focused on high-end smart home appliances. When developing their new generation of premium fans, they encountered significant technical bottlenecks regarding noise, energy efficiency, and motor stability.
- High Noise Levels: Traditional square-wave drives created excessive commutation noise.
- High Energy Consumption: Outdated systems failed to meet Level 1 efficiency standards.
- Poor Low-Speed Stability: Noticeable jerking at low speeds prevented a "natural wind" experience.
The Ruichun Solution
Ruichun engineered an optimized sensorless FOC BLDC fan control board:
- Sensorless FOC: Precision current control for superior efficiency.
- Sine Wave Drive: Eliminated mechanical and electromagnetic noise.
- Stepless Adjustment: Guaranteed smooth speed transitions.
Results & Market Impact
The new series achieved a 60% noise reduction and perfected the "natural wind" sensation, significantly boosting product market competitiveness.
"Ruichun Technology not only provided technological solutions, but also brought a profound transformation in our product philosophy."
