Dc brushless fan is a fan based on DC brushless motor, which is mainly composed of four parts: rotor, stator, frame and motor. The motor part includes a circuit board and a silicon steel sheet, and the pulse generator of Hall element is integrated on the circuit board, which has the advantages of strong anti-interference ability and no electromagnetic interference.

The working principle of the DC brushless fan is to control the rotation of the motor through the pulse generator of the Hall element, so as to realize the rotation of the fan. The speed and air volume of the DC brushless fan can be controlled by adjusting the current, voltage and frequency of the motor to meet different heat dissipation requirements.

The advantage of DC brushless fans is that they have a high speed and air volume, which can provide a strong heat dissipation effect. At the same time, due to the use of brushless motors, DC brushless fans have lower noise and longer service life.

Dc brushless fans are widely used in electronic and electrical applications that require forced heat dissipation, such as computers, servers, home appliances and other equipment. In addition, DC brushless fans can also be used for heat dissipation in automotive, aerospace and other fields.
