The Working Principle of DC Cooling Fans
From:Fastflag July 3, 2023

DC cooling fan mainly consists of a motor rotor, stator, fan blades and other auxiliary components combined. There are many semiconductor components in the control circuit, and today's technology can already put multiple semiconductor components in one or more ICs, and many manufacturers will specialize in designing a variety of models to control the motor IC power road user design. Different models of IC control circuits are different, but the main purpose of these designs is to provide more effective control and protection for the DC cooling fan to provide coil function. 

The working principle of DC cooling fan is mainly through DC voltage and electromagnetic induction, the electrical energy into kinetic energy, which drives the rotation of the fan blades, relying on the coil and IC constantly switch, induction magnetic ring from driving the air blades rotating cooling equipment.
