1. EC fans includes AC input driven brushless DC fan with integrated design of AC-DC transformation circuit, the PFC circuit, the BLDC drive circuit, interface circuit. Due to the internal integration of the AC-DC converter circuit, the consumption of power will be reduced to facilitate the design and application of the overall power system in customer.

2.  Brushless DC external rotor motor belongs to non-mechanical brush(commutator)DC motor which enforces the winding current commutation through electronic commutator (position sensing, non-position sensing),achieve the speed control function with PAM or PWM control



Energy savings : Minimum power consumption & better efficiency than AC equivalent.
Control : 100% speed controllable, not frequency dependant. Can be set-up for constant airflow or constant pressure applications, 0-10VDC or PWM control signal.
Low motor temperature : for longer lifetime than AC equivalent
Simplicity : Electronic & power transformation are completely integrated within the motor.
High performance : Speed can be driven up to 3600rpm, one EC fan replace multiple type of motors (2, 4 and 6 pole)
Easy connection : No complicated wiring and set-up with a Frequency Controller, EC fans have very little configuration.


1. Are you a factory or trading company?

We are a factory which specialized in produce external rotor motor about 10 years. We accept OEM or ODM

2. 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.

3. Can we buy a sample for testing?

Sure, you are welcomed to buy a sample before mass order.



Design operating temperature range: -30~60 degrees of minimum selection(The device in accordance with -40~85 degrees)

Protection: over voltage, over temperature, over current, phase loss detection, communication failures.

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
