There is no support for forward curved multi-blades centrifugal fan from 133mm-630mm. Other model have the support. And there is no current collector for backward curved impeller centrifugal fan. You need to inform us if you want the support or current collector for fan model, clarify the fan model, specification, air volume and static pressure before placing an order. Forward curved multi-blades centrifugal fan and back curved impeller centrifugal fan, please take note on the air direction

 

EC Fan Introduction

 

EC(Electronically Commutation) motors, as built-in DC inverter driver three phase AC external rotor permanent magnet synchronous motors, its efficiency and low noise is considered to be ultimate fan energy technologies.

 

Core Technology Of EC Fan Controller

1. Sensorless vector control software

2. High-performance power electronic circuits

3. Security and reliability design(Standards, Certification)

4. Embedded design

 

External rotor axial fans series product:

1.Compact configuration, convenient installation and credible running

2. Pressure high, airflow stable

 

 

Brushless DC motors have been around for many years but there has always been the need for a separate DC power supply. In applications using only an AC supply this introduced added cost and complexity. Then, in 2003, ebm-papst brought out an EC fan with integrated electronics which could be connected directly to an AC mains supply. In addition to performing the commutation, the electronics convert AC to DC and control the fan speed by regulating the power to the motor.

Put simply, DC motors are around 30% more efficient than AC motors because the secondary magnetic field comes from permanent magnets rather than copper windings. An AC motor consumes additional energy solely to create a magnetic field by inducing a current in the rotor. But this is only half the story. The use of modern electronics in controlling the motor has opened up many other possibilities which contribute to using less power.
