The working principle and characteristics of dc cooling fans

We all know, dc cooling fan is a kind of important modern automobile mechanical cooling equipment, it consists of the stator, rotor and commutator of three local, its basic structure by ordinary motor, bearing, blade, shell ( The fixed hole) A few local composition, the plug and wire. Due to work or environmental reasons, many devices are in high temperature, dust, humid air is relatively harsh environments such as operation, many industry demand is applied to the dc cooling fans, then you know how dc cooling fan works? What dc cooling fan fan, dc cooling fan manufacturer to inform us, dc cooling fan is a dc voltage and electromagnetic induction, and by the electrical energy into mechanical to drive the blades rotating, referred to as dc cooling fans. It depends on the coil and IC switch from time to time, 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 a current through the winding, the function of the magnetic field and stator magnetic field to produce force. Because the stator is fixed, so the rotor under the action of force rotating commutator of the dc cooling fan is a kind of special installation of dc motor, comprising a number of commutator segment, every two adjacent commutator segment is insulation piece in the middle. In a commutator with the appearance of spring pressure fixed 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 of electromagnetic torque constant, in under the action of the electromagnetic torque to rotate the armature.
