I believe we all know or used "Micro Cooling Fan" it, then you find out about the components of a DC fan What do the following Xiaobian for you a detailed explanation by the DC fan manufacturers?:
    1, the fan motor parts: including circuit boards, control energy consumption and signal access, silicon (ie the stator magnet, the coil winding attached) generates a magnetic level to promote the switch on silicon, under cover, fixed and insulated.
    2, cooling fans Frame: play a supportive role in the fan motor and diversion.
    3, "Micro Cooling Fan" stator section: Includes support spring, separate balance bearing spindle bearings, providing high speed, low friction, long life rotating, buckles, fixed tuberculosis rotating the entire assembly, electrical parts, production and direction of rotation, the size of the rotational speed of the active key.
4, "Micro Cooling Fan" Rotor: it includes fan blades, is a source of generating an air flow, the fan axis, to support balanced rotating blades, rotor magnetic, permanent magnets, magnetic level switching speed push key ring frame, fixing ring.
