"Mini Air Cooling Fan" in more than two rotor coil winding made from enameled wire, called windings. Generates a magnetic field when a current passes through the windings, the role of the magnetic field and the stator magnetic field generating power. Since the stator is stationary, so the rotor is rotated under the action of forces. Commutator is a special device "Mini Air Cooling Fan" DC motor, by changing the composition of a number of segments, each two adjacent commutator intermediate insulating sheet. The surface of the commutator by a spring pressing the brush fixed, so that rotation of the armature winding can be coupled with an external circuit. When the "Mini Air Cooling Fan" rotor turned at an angle, the commutator will access another supply voltage windings, and continue to produce a magnetic field in the windings.
