Structure of DC cooling fan

There are two main parts of a DC micro fan, the rotor and the stator, which are subdivided as follows:

1. Fan frame: supporting the fan motor and diversion

2. Fan rotor part: including fan blades, which are the source of air flow, the fan axis, which is used to support the rotation of the balanced fan blades, the rotor magnetic ring, and the permanent magnets. Magnetic ring

3. Fan motor part: including circuit board, control energy consumption and signal access, silicon steel sheet (that is, stator magnet, attached winding coil) to generate magnetic level propulsion switching, silicon steel sheet upper and lower covers, fixation and insulation;

4. Fan stator part: including supporting spring, separate bearing to balance shaft and bearing, provide high speed, low friction, long life rotation, buckle ring, fixed nodules to rotate the whole part, motor part, production rotation direction, active size and rotation speed The essential
