The structure and classification of DC brushless cooling fan
What is a brushless DC cooling fan? What is it mainly composed of, and how is it classified? Here, the company’s professional cooling fan technicians will tell you the structure and classification of brushless DC cooling fans: The structure of brushless DC fans: Mainly can be divided into rotor (rotor), stator (composition: stator core , Stator windings and base), the frame, the motor (motor, engine) and some other fragmentary parts of these four main parts. First, the fan rotor (rotor) part: includes fan blades, which are important for generating air flow The axis of the cooling fan is used to support the rolling of the balanced fan blades, the rotor magnetic ring, permanent magnets, and the key to promote the magnetic level switching speed (explanation: an important part of the metaphor), the magnetic ring frame, fixed (fixed) ) Magnetic ring second, the fan stator (composition: stator core, stator winding and frame) part: includes (bāokuò) support (sustain) spring (huáng), separate bearing (bearing) balance shaft, bearing, provide high Rotation speed, low friction, long life (lifetime) rotation, buckle, fixed (fixed) nodules to rotate the entire component, motor part, production rotation direction, active size, rotation speed is key (explanation: an important part of a metaphor) third, heat Fan frame: plays the role of supporting (sustain) the fan motor, engine and diversion; fourth, the fan motor part includes (bāokuò) circuit board, control (control) energy consumption and signal access, silicon steel (ie stator) (Composition: stator core, stator winding and frame) magnets, with winding coils attached to it to produce magnetic level propulsion switching, silicon steel sheet upper and lower covers, fixed and insulated bodies. The cooling fan technology and performance have reached a mature stage, and new technologies continue to appear. Fan specifications range from 8mm to 280mm, voltages are 5V, 12V, 24V, 48V, 110V, 220V, 380V, and the shapes are square, round, olive, etc. Classification of brushless DC cooling fans: can be divided into four types according to different bearings: 1. Single ball bearing brushless fan, 2. Laifu bearing brushless fan, 3. Hydraulic (hydraulic) bearing brushless fan, 4. Four types of nano-bearing brushless fans. DC brushless fan specifications (specifications) generally have 6c M, 7c M, 8c M, 9cm. A few radiators (to reduce the heat generated when the device is running) have begun to use 12cm ultra-large diameter fans. The fan size and regulations (guīdìng) ) Are usually marked with four digits. Through DC voltage and electromagnetic induction, the DC fan converts electrical energy into machinery to drive the rotation of the blades. Collectively referred to as DC fan blower, it is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base (and fuel tank), Drip nozzle. The blower operates eccentrically on the rotor offset in the cylinder, and changes the volume between the blades in the rotor slot to suck in, compress, and discharge air.
