A DC fan is a cooling fan that converts electrical energy into electromagnetic energy via DC voltage and electromagnetic induction, then electromagnetic energy into mechanical energy, and finally kinetic energy, causing the fan blades to rotate. These are lightweight and can be mounted to a moving carriage without impacting on its performance. DC cooling Fans are used with 3d Printers , Raspberry Pi , computers and more,.


The stator and transfer are the two most important parts of a DC fan. The ampere right-hand rule tells us that a conductor conducts current and generates a magnetic field around it. When this conductor is placed in another fixed magnetic field, it generates attraction or repulsion, causing the object to move. A rubber magnet filled with magnetism is attached inside the fan blade, surrounding the silicon steel sheet, and the shaft core part is wound with two sets of coils, and the Hall sensor component is used as a synchronous detection device to control a set of circuits. The circuit causes the two sets of coils wrapped around the shaft core to work in reverse, producing different magnetic poles on the silicon steel sheet, and this magnetic pole and the rubber magnet generate repulsive force. The fan blades will rotate naturally when the repulsive force is greater than the static friction of the fan. The fan blades can continue to spin due to the synchronization signal provided by the Hall sensor components, and the rotational direction is determined by Fleming's right-hand rule and the DC fan or cooling fan operates on this principle. You can find here a wide range of cooling fans like 5v dc fan, 12v dc fan, 24v dc fan and more. There are a few essential components required while using a dc fan and they are microcontrollers like Arduino , jumper wires , soldering tools , hot glue guns , batteries or power supply and  switches.

1. What is a DC fan?

  • A DC fan is a type of cooling fan that converts electrical energy into electromagnetic energy via DC voltage and electromagnetic induction, then electromagnetic energy into mechanical energy, and finally kinetic energy, which causes the fan blades to rotate.


2. Are DC fans better than AC fans?

  • DC fans are generally better than their Ac counterparts.
  • they use less energy – up to 70% less than a standard AC fan.
  • They are generally extremely quiet.
  • They will often have more speed options, the reverse function on the remote, and are generally faster to start, stop and change speed.
  • The motor is generally more compact and lighter, which allows for a slimmer motor design.


3. How do DC fans work?

  • A DC fan works pretty much on the same principle as the DC motor. A DC motor uses an internal arrangement of magnets with opposing polarity. As current passes through the coil around this arrangement, a strong magnetic field is produced. This magnetic field then creates a torque that causes the motor to rotate.


4. What is the difference between DC fans and AC fans?

  • The difference between the two fans lies in the way they operate. AC motor fans operate by directly connecting it to standard power that creates the energy and force needed to run the motor. DC fans have an in-built transformer that converts the standard power to DC. This decreases the amount of power used on all fan speeds, as the fan is only utilizing a direct current instead of an alternating current. 


5. How to power a DC fan?

  • A DC fan can be powered directly via battery or by plugging it directly into the GPIO power pin for instant cooling effect. It can also be powered via AC power supply by using AC to DC converter.
