Cooling dc cooling fan, as we all know, is a kind of important modern industrial machinery cooling device, it is composed of stator and rotor and commutator of three parts, its basic structure by general motors, bearings, blade, shell (
The fixed hole)
A few parts, power plug and wire.
And due to work or the environment, many devices are in high temperature, dust, air humidity is relatively harsh environments such as running, many industries need to be applied to the heat dissipation dc cooling fan, then you know how heat dc cooling fan works?
What radiator cooling fan dc cooling fan, radiator dc cooling fan manufacturer told us, heat dissipation dc cooling fan is by dc voltage and electromagnetic induction, the electrical energy into mechanical to drive the blades rotating, collectively known as heat dc cooling fan.
It depends on the coil and switch IC, induction magnetic ring from turns the blades.
Have more than two sets of coil in the rotor, the enameled wire winding and become, called winding.
A magnetic field when the winding of an electric current passes through, the function of the magnetic field and stator magnetic field to produce force.
Because the stator is fixed, the rotor under the action of force rotating commutator of the dc radiator cooling fan is a kind of special equipment of dc motor, comprising a number of commutator segment, every two adjacent commutator segment is insulation piece in the middle.
With a spring pressure on the surface of the commutator brush, with external connection rotation of the armature winding.
Turned a certain Angle, when the rotor commutator access another pair will supply voltage winding, and continue to produce magnetic field in the winding.
Visible, but because of the commutator, the armature coil by electromagnetic torque remains unchanged, in under the action of the electromagnetic torque to rotate the armature.
How is heat dc cooling fan?
