PMSM External Rotor Single Inlet Forward-Curved EC Centrifugal Fan‌

PMSM External Rotor Single Inlet Forward-Curved EC Centrifugal Fan‌

Advantages:

• Ultra-High Efficiency‌

Permanent magnet excitation eliminates rotor losses, achieving >90% system efficiency under variable loads.

• Compact Power Density‌

Outer-rotor topology + high-flux PMSM enables 30% higher power/volume ratio vs. conventional motors.

• Precision Airflow Control‌

FOC algorithm maintains ±1% constant static pressure with rapid <100ms dynamic response.

• Low Acoustics‌

Sinusoidal drive + forward-curved aerodynamics reduce noise to 45 dB(A) at 1m distance.

• Zero Maintenance Design‌

Brushless operation + IP54 sealing ensures 80,000+ hours service life in harsh environments.

• Optimized Air Performance‌

Forward-curved blades deliver 40% higher static pressure at low RPMs for HVAC applications.
