A DC fan, as you can tell from its name, is a fan that operates using direct current. Its power supply voltage is fixed, and it needs to rely on circuit control to generate different magnetic fields, and its core components are stator and rotor. Although cooling fans are divided into two types of DC and AC, DC fans have a greater market share in more and more applications, characterized by high wind pressure, high air volume, long service life, low noise, good operational stability, good speed performance, simple control.

The working principle of DC fan is to rotate the rotor through DC voltage and electromagnetic induction. The Hall sensing assembly inside the DC fan provides a synchronization signal to keep the fan blades running. The rotor and stator of a DC fan are its core components, and the electromagnetic induction between them creates the rotational force of the rotor, which turns the fan blades.

The working principle of a DC fan can be simply summarized as follows: DC current generates a rotational force through electromagnetic induction between the stator and rotor, which drives the fan blades to rotate. The speed and airflow of a DC fan can be controlled by adjusting the voltage and current of the DC current.

Advantages of DC fan applications include high air pressure and air volume, long service life, low noise, good operational stability, good speed regulation, and simple control. Therefore, DC fans are widely used in many fields, such as computers, automobiles, communication equipment, purifiers and other industries, with a wide range of applications and a huge market size.

In a nutshell, the working principle of DC fan is to generate rotational force through DC current and electromagnetic induction, which drives the fan blades to rotate. The advantages of DC fans are high air pressure, high air volume, long service life, low noise, good operational stability, good speed regulation and simple control. Therefore, DC fans are widely used in many fields.
