Cooling fans have a wide range of applications, and there are many types of cooling fans, but their structure is similar, mainly composed of four parts: rotor, stator, motor, and outer frame. I believe that there are still many people who don’t know much about it. The following Xiaobian will introduce the components of the cooling fan in detail.
1. Rotor part: The rotor part of the cooling fan is composed of fan blades, shaft center, rotor magnetic ring, and magnetic ring outer frame. The fan blade is used to create air flow; the shaft center is to support the rotation of the balanced fan blade; the function of the rotor magnetic ring is the key to promote the switching speed of the magnetic stage; the outer frame of the magnetic ring is used to fix the magnetic ring.
2. Stator part: The stator part of the cooling fan includes bearings, support springs, retaining rings, etc. Among them, the role of the bearing is to high speed, reduce friction, and ensure that the fan can run for a long time. The support spring is used to separate the bearing balance axis; the retaining ring is used to fix the rotating whole part. The outer frame plays the role of support and diversion.
3. Motor part: The motor part of the cooling fan includes: the circuit board, which controls energy consumption and signal in and out; the silicon steel sheet (that is, the stator magnet, with the winding coil attached to it) generates the magnetic level propulsion switching; the upper and lower covers of the silicon steel sheet are used to fix and insulation.
4. Outer frame part: The outer frame part of the cooling fan mainly plays the role of support and diversion.
