Details Introduction
Brushless DC Blower Controller
Developed by Sounds Electric, this DC brushless blower control module combines FOC vector control with intelligent air pressure tracking, setting a new benchmark for energy efficiency and noise reduction. It supports smooth speed adjustment from 800 to 1500 RPM with 1% precision, improves airflow pressure stability by up to 40%, and cuts energy consumption by 35%—all while delivering whisper-quiet operation and long-lasting, stable performance.
▌Core Technology Highlights:
• Intelligent variable-Frequency Drive: Features sensorless sine wave control to drive the three-phase motor with real-time magnetic field angle calculation. Torque ripple is kept below 5%, supporting both forward and reverse airflow startup.
• Full Digital DSP Control: Equipped with a 32-bit digital signal processor, providing millisecond-level dynamic response and adaptive load regulation, featuring adaptive airflow pressure compensation.
• Comprehensive Protection System: Integrates overcurrent, overvoltage, overheat, and phase-loss protection, extending IPM module lifespan by up to 50%.
• Wide Voltage Compatibility: Supports 90–264VAC input range for stable operation under complex power grid conditions.
• Ultra-Quiet Technology: Frequency modulation and mechanical resonance suppression reduce operational noise to ≤45 dB at 1 meter.
▌Application Advantages:
• Wide Performance Range: Compatible with brushless DC motors across 170V/310VDC platforms, supporting power from 30W to 120W.
• Advanced Thermal Design: Turbine airflow channel keeps temperature rise under 35°C during continuous full-load operation.
•Streamlined Integrated Design: Features onboard terminals to support multiple speed settings.
Sounds Electric is ISO 9001 certified and has specialized in power electronics control for over 30 years, advancing smart appliance innovation through core board-level technologies.
