brushless dc fan,
dc centrifugal blower
133mm DC Centrifugal Fan With 48v Fresh Air System PA66 Air Purification
Brushless dc fan use a permanent magnet excitation, eliminate the loss of induction motor excitation currents; realizing the small loss an high
Compared with the frequency control of induction motor, brushless dc ,motor is simpler and more controllable, easy to perform control
The components, such ac inverters etc, whose capacity is low, and circuit are simpler, the cost lower than ec blower’s
OFAN provides the most comprehensive services, includes: product diversification, against the clock delivery, documents support, and technical consulting service. “Customer is partner” is key to our success; ”Win the contract for customer” is our ultimate goal.
Protection: over voltage, over temperature, over current, phase loss detection, communication failure
The basic interface: 0-10V/PWM, RS485/Modbus, 4-20Ma
The basic parameters of field programmable: Maximum speed, minimum speed, maximum power, maximum current,resonance avoid
Constant air pressure controlling function
Electro magnetic compatibility (EMC)
How do I know which model I should choose
Please tell us the fans pressure and ofan and size of fans’ diameter you need. We will study and suggest you the right model.
Can we buy a sample for testing?
Sure, you are welcomed to buy a sample before mass order.
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
