    The available range of AC input EC fans is expanding all of the time. There are axial and centrifugal fans, forward curved and backward curved, single inlet and double inlet, single phase and three phase and they are often directly interchangeable with their AC equivalents. EC offers the OEM more than just energy-efficiency. It is an opportunity to bring new technology and functionality to their products. With ever-increasing demand for energy efficient systems, when it comes to fan based products, there’s no reason for manufacturers not to have any in their portfolio.

     

    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.

    Control options
    To control the motor accurately and efficiently the integrated electronics have to continuously monitor the motor speed and adjust the control input. By making this circuitry available to external sources it’s possible to provide simple speed control options. Dependent on the motor type, any sensor which can provide a 0-10V/PWM or 4-20mA input can be directly connected to provide closed loop control for temperature, pressure or whatever parameter you choose to measure. No need to worry about DC supplies for the sensors either, this is provided by another connection on the motor. In fact, simply connect a potentiometer and you have infinitely variable speed control. No triacs, no frequency inverters and no whining noises! An EC motor under speed control is virtually

     

    Very high degree of efficiency

    Integrated controller (continuous control)

    Very simple connection

    Additional functions (pressure control, airflow, speed, temperature, air quality, etc.)

    Smaller-sized motor for the same level of performance

    Less power consumption

     

    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

     

    Enable the selection of different power levels thus to get the best match of price and performance according to customers’load requirements

     

     

    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
