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.
