    Blower Performance

    12vdc brushless mini centrifugal air blower motor fan can reach maximum 8m3/h airflow at 0 kpa pressure and maximum 4.8 kpa static pressure.It has maximum output air power when this blower run at 3kPa resistance if we set 100% PWM, It has maximum efficiency when this blower run at 3.5kPa resistance if we set 100% PWM. Other load point performance refer to below P-Q curve:


    DC Brushless Blower Advantage

    (1).12vdc brushless mini centrifugal air blower motor fan is with brushless motors and NMB ball bearings inside which indicates very long life time

    (2).MTTF of this blower can reach more than 20,000 hours at 20 degree C environmental temperature.

    (3).This blower drived by a brushless motor controller have many different control functions such as speed regulation,speed pulse output,fast acceleration, brake etc.

    (4).It can be controlled by intelligent machine and equipment easily.

    Drived by brushless motor driver the blower will have over current, under/over voltage,stall protections.

    How to Use the Blower Correctly



    Q: Can you design a new blower fan if we give you target performance?

    A: Yes, we offer ODM service for both blower fan and controller board.

    Q: What can do if the working condition is dirty?

    A: A filter is strongly recommended to assemble onto the the inlet of the blower fan

    Q: How to decrease the noise of the blower?

    A: Many of our customers use foam, silicone to fill between blower fan and machine to insulate the blower noise.

    If external mechanical power is applied to a DC motor it acts as a DC generator, a dynamo. This feature is used to slow down and recharge batteries on hybrid and electric cars or to return electricity back to the electric grid used on a street car or electric powered train line when they slow down. This process is called regenerative braking on hybrid and electric cars. In diesel electric locomotives they also use their DC motors as generators to slow down but dissipate the energy in resistor stacks. Newer designs are adding large battery packs to recapture some of this energy.
