The main is to learn and master the "Tiny Cooling Fan" of the exterior structure, operation principle of the fan, the fan's performance, specifications, and so on. First, tell us about the basic structures of the fan (with Axial DC brushless fan as an example) is mainly composed of a total of four parts:
1. The rotor parts, including blades, shaft, rotor ring, ring frame;
2. The stator section, including "Tiny Cooling Fan" support springs, bearings, buckles;
3. The frame part, mainly from the support, diversion effect;
4. Motor parts, including circuit boards, silicon (ie stator magnet windings on attached) on silicon, under cover; the parts according to the function, and the impact on "Tiny Cooling Fan" performance, life can be roughly divided into motors, bearings, blades and frame four parts. The following is the operation principle of the fan
