    DC Brushless Blower Advantage

    (1) WS9250-24-240-X200 blower is with brushless motors and NMB ball bearings inside which indicates very long life time; MTTF of this blower can reach more than 15,000hours at 20 degree C environmental temperature

    (2) This blower needs no maintence

    (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.it can be controlled by intelligent machine and equipment easily

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

    Applications

    This blower can be widely used onto air pollution detector,air bed,air cushion machine and ventilators.

    How to Use the Blower Correctly

    This blower can run at CCW direction only.Reverse the impeller running direction can not change the air direction.

    Filter onto the inlet to protect the blower from dust and water.

    Keep the environmental temperature as low as possible to make the blower life time longer.

    FAQ

    Q: What is the MTTF of this centrifugal air blower?

    A: MTTF of this centrifugal air blower is 20,000+ hours under 25 C degree.

    Q: Can we use this centrifugal air blower to suct water?

    A:This blower fan can not be used to suck water. If you need to suck water, you can ask us to choose proper item for this special working condition.

    Q: Can we use this centrifugal air blower to suck dust directly?

    A: This blower fan can not be used to suck dust directly.If you need to suck dust, you can ask us to choose proper item for this special working condition.

    The speed of a DC motor can be increased by field weakening. Reducing the field strength is done by inserting resistance in series with a shunt field, or inserting resistances around a series-connected field winding, to reduce current in the field winding. When the field is weakened, the back-emf reduces, so a larger current flows through the armature winding and this increases the speed. Field weakening is not used on its own but in combination with other methods, such as series-parallel control.
