DC fan is a kind of rotary fan. It belongs to DC motor. Its main working principle is to convert electric energy directly into mechanical energy. This type of fan is common in computer power supplies, server operations, automotive air conditioning systems and automotive electronics. 9LG0812H4001 is a model of DC fan. It is a small and low noise DC fan.

9LG0812H4001 mainly consists of fan blades, fan frame, fan housings, bearing shaft, motor, control circuit and other components. The main materials used are plastics, aluminum and steel plates. The frame is fixed to the stator to ensure the stability of the fan. The fan housing can protect the internal components from dust and other debris. The motor is a DC permanent magnet motor, its working principle is electric energy input， it will drive the rotor rotation to achieve the purpose of cooling. It is very efficient.

The main working principle of 9LG0812H4001 is the same as other DC fans. It is the electromagnetic reaction of the winding and the magnetic field that causes the motor shaft to rotate. The control circuit can control the speed and direction of rotating. It can also detect the rotation speed and protection temperature of the fan. The fan blade is fixed to the motor shaft for rotation. The air sucked by the fan blade forms an air flow, which is output from the fan.

9LG0812H4001 is usually used in 1U small server, CNC machine tools, three-dimensional printer, automation equipment, communication equipment, household appliances and other electronic products. Compare with AC fans, DC fans have higher efficiency, low noise, more energy saving and longer service life. It is an ideal device for cooling.
