FAQ

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.
