Through DC voltage and electromagnetic induction, electrical energy is converted into machinery to drive the rotation of the blades, which are collectively referred to as DC fan.

According to the principle classification, fans can be divided into two categories: AC axial fans and centrifugal fans. These two types of fans have different structures, different working principles, and different operating characteristics.
