80mm mini size 13.3kPa pressure 24CFM WS9290B 24V brushless DC plastic housing light weight centrifugal blower.

Suitable for vacuum machine/fuel cell/medical equipment and inflatables.

(1)WS9290B-24-220-X300blower is with brushless motors and NMB ball bearings inside which indicates very long life time; MTTF of this blower can reach more than 20,000hours 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.

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

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.

Q: What kind of power supply shall we use to drive this blower fan?

A: Generally, our customer use 24vdc switching power supply or Li-on battery.

Q: Do you also sell controller board for this blower fan?

A: Yes, we can supply adapted controller board for this blower fan.

Q: How to change impeller speed if we use your controller board?

A: You can use 0~5v or PWM to change speed. Our standard controller board is also with a potentiometer to change speed conveniently.

Brushed DC motors are constructed with wound rotors and either wound or permanent-magnet stators.

Generally, the rotational speed of a DC motor is proportional to the EMF in its coil (= the voltage applied to it minus voltage lost on its resistance), and the torque is proportional to the current. Speed control can be achieved by variable battery tappings, variable supply voltage, resistors or electronic controls. A simulation example can be found here and.The direction of a wound field DC motor can be changed by reversing either the field or armature connections but not both. This is commonly done with a special set of contactors (direction contactors). The effective voltage can be varied by inserting a series resistor or by an electronically controlled switching device made of thyristors, transistors, or, formerly, mercury arc rectifiers.
