EC Fans'Technical Features Overview

PBM series EC (Electronically Commuted) Fans combine interactively external motor technology, integrated electronic control circuit and aerodynamic design of fan impeller that satisfied customers' requirements in different applications and industries by innovative air-moving solutions. We are pursuing Ultra-low Energy Consumption fans by extremely compact brushless permanent magnet synchronous external rotor motor to drive various of aerodynamic optimized impeller and scroll-housing types and sizes: diagonal axial, backward and forward curved centrifugal, radial, single inlet and dual inlet blower, tangential, cross flow.

Impeller Sizes:From minimum 30mm to 560mm diameter;

Sound Level:From 31dB(A) to maximum 82dB(A) according different rotation speed;

Airflow:Maximum to 16,300CMH, Cubic Meter per Hour, equal to approx. 9,593CFM , Cubic Feet per Minute;

Air Pressure:Maxim to 1,700Pa, equal to 173.5mm H₂O and to 6.82 inches H₂O;

Power:Maximum motor input power goes to 3.1KW (equal to 4.2hp, horsepower) at motor diameter 138mm.

Eco-friendly EC Motor Technology Introduction

EC=Electronically Commutated

EC brushless permanent magnet synchronous external rotor motor compact with integrated electronic controller built-in for fan applications.

  • Voltage stabilizer with silicon rectifier; no surge current by soft-start and PFC circuit integrated;
  • Motor efficiency goes up to Maximum 91% for energy-saving and emissions-reducing;
  • Low noise by sine wave 3-core brushless commutation motor design with oblique magnetization;
  • Always rotation in the correct direction;
  • Operating at either 50Hz and 60Hz;
  • Operating at a wide voltage range
    184~276 V AC 1~;
    380~480 V AC 3~
  • Operating temperature rise is much cooler in electric motors for longer lifespan;
