Automobile cooling fan manufacturers tell you how DC cooling fans work
Automobile cooling fan manufacturers believe that everyone knows that DC cooling fan is an important cooling equipment for modern automobile machinery. It consists of three parts: stator, rotor and commutator. Its basic structure is generally composed of motor, bearing, blade, and shell. (Including fixing holes), power plugs and wires. However, due to work or environmental reasons, many devices have to operate in harsh environments such as high temperature, heavy dust, and humid air. Many industries need to apply DC cooling fans, but do you know how DC cooling fans work? If you know, let's take a look at it with the editor of the car cooling fan manufacturer.

u003cbru003e What kind of fan is a DC cooling fan? Automotive cooling fan manufacturers tell you that DC cooling fans convert electrical energy into machinery through DC voltage and electromagnetic induction to drive the rotation of the blades, collectively called DC cooling fans. It relies on the coil and IC to switch continuously, and the induction magnetic ring drives the wind blade to rotate.

The automobile cooling fan manufacturer tells you the effect of the magnetic field and the magnetic field of the stator. Since the stator is fixed, the rotor rotates under the action of force

u003cbru003e The commutator of the DC cooling fan is a special device of the DC motor, which is composed of many commutator segments, and the middle of every two adjacent commutator segments is an insulating sheet. The fixed brush is pressed by a spring on the surface of the commutator, so that the rotating armature winding can be connected with the external circuit. The automobile cooling fan manufacturer tells you that when the rotor rotates through a certain angle, the commutator connects the supply voltage to another pair of windings and continues to generate a magnetic field in this winding. It can be seen that due to the existence of the commutator, the electromagnetic torque received in the armature coil remains unchanged, and the armature can be rotated under the action of this electromagnetic torque.
