Information

The cooling fan can be divided into two types according to the power supply type: DC fan and AC fan. However, in terms of physical composition, DC fan and AC fan have the same basic structure: what is the structure and function of DC fan in fan blade, rotor, stator, fan frame and bearing system? Details are as follows:

1. Fan frame: support fan motor and guide air flow

2. Fan rotor part: including fan blades, which are the source of air flow and fan axis. Fan rotor part: it is used to support balance fan blade, rotor magnetic ring, permanent magnet, key to push magnetic grade to switch speed, outer frame of magnetic ring and rotation of fixed magnetic ring.

3. Fan motor part: including circuit board for controlling energy consumption and signal input and output, magnetic level propulsion switch generated by silicon steel sheet (i.e. stator magnet and upper winding coil), upper and lower cover of silicon steel sheet, fixation and insulation;

4. Fan stator part: including support spring, which separates the center of bearing balance shaft and bearing to provide high speed. Low friction. Long life rotation, retaining ring, whole part of fixed nodule rotation, motor part, production rotation direction and dynamic rotation speed are the key points.

Shenzhen Jiangshanlai Electronics Technology Co., Ltd. was established in 2005. Located in Shenzhen, China, is a professional manufacturer of DC brushless motors, DC cooling fans, DC brushless fans, DC bracket fans, booster cooling fans, mini cooling fans, DC cooling fans, DC fans, non-standard fans, R & D and manufacturing , Sales, and service.
