Structure of DC brushless fan: It can be divided into four main parts: rotor, stator, frame, motor (motor) and some other components.
First, the fan rotor part:
Including the fan blade, which is the core of the air flow, the axis of the cooling fan, used to support the balance fan blade rolling, the rotor magnetic ring, the permanent magnet, the propulsion magnetic level switching speed key, the magnetic ring frame, the fixed magnetic ring
Second, the fan stator part:
Including the support spring, separate the bearing balance shaft, bearing, provide high speed, low friction, long life rotation, buckle, fixed tuberm rotation of the whole part, motor part, production rotation direction, active size rotation speed key
Third, the cooling fan frame:
Supporting the fan motor and guiding action;
Fourth, the fan motor part
Including the circuit board, control energy consumption and signal in and out, silicon steel sheet (ie, stator magnet, winding winding) to produce magnetic grade propulsion switching, silicon steel sheet upper and lower cover, fixed and insulator.
Classification of DC brushless cooling fans:
According to the different bearings can be divided into four types: 1. Single ball bearing brushless fan, 2. Laifu bearing brushless fan, 3. Hydraulic bearing brushless fan, 4. Nano bearing brushless fan four. DC brushless fans are generally available in sizes of 6cm, 7cm, 8cm, and 9cm. A few heatsinks start with 12cm large diameter fans. The size and specifications of the fan are usually marked with four digits.
The above is the structure and classification of the brushless fan in the DC fan. The three professional production and development of the cooling fan, DC fan, and fans of all walks of life.
