Blower Performance

WS145110-48-150-X300 blower can reach maximum 29m3/h airflow at 0 kpa pressure and maximum 30kpa static pressure.It has maximum output air power when this blower run at 18kPa resistance if we set 100% PWM, It has maximum efficiency when this blower run at 16kPa resistance if we set 100% PWM.Other load point performance refer to below P-Q curve:

DC Brushless Blower Advantage

(1) WS145110-48-150-x300 blower is with brushless motors and NMB ball bearings inside which indicates very long life time; MTTF of this blower can reach more than 30,000hours at 20degree 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 vacuum machine,fuel cell.

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: 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.

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.

Since the series-wound DC motor develops its highest torque at low speed, it is often used in traction applications such as electric locomotives, and trams. Another application is starter motors for petrol and small diesel engines. Series motors must never be used in applications where the drive can fail (such as belt drives). As the motor accelerates, the armature (and hence field) current reduces. The reduction in field causes the motor to speed up, and in extreme cases the motor can even destroy itself, although this is much less of a problem in fan-cooled motors (with self-driven fans). This can be a problem with railway motors in the event of a loss of adhesion since, unless quickly brought under control, the motors can reach speeds far higher than they would do under normal circumstances. This can not only cause problems for the motors themselves and the gears, but due to the differential speed between the rails and the wheels it can also cause serious damage to the rails and wheel treads as they heat and cool rapidly. Field weakening is used in some electronic controls to increase the top speed of an electric vehicle. The simplest form uses a contactor and field-weakening resistor; the electronic control monitors the motor current and switches the field weakening resistor into circuit when the motor current reduces below a preset value (this will be when the motor is at its full design speed). Once the resistor is in circuit, the motor will increase speed above its normal speed at its rated voltage. When motor current increases, the control will disconnect the resistor and low speed torque is made available.
