DC Fans

DC fans are used for cooling, exhausting or gas circulation in various types of electrical, electronic, mechanical, and chemical equipment. They are widely used in ventilation and air-conditioning systems, power supplies, computers and networks, vehicles, consumer electronics, medical equipment, and other industrial and control applications.The G8020E12B1-RSR is a brushless DC fan that combines a high air volume with low noise. It features a compact design, low power consumption, and a long service life. The fan also comes with an integrated over-temperature protection function to ensure that the device won’t overheat while running.

Application Field

The G8020E12B1-RSR is mainly used in laptops, digital cameras, projectors, DVD players, and other electronic equipment. It is also suitable for high-power applications such as power supply boards, power amplifier boards, and home audio systems.

Working Principle

The G8020E12B1-RSR uses a brushless DC motor for operation. A DC motor consists of a rotor and a stator, and is connected to a power supply that sends high-voltage electricity to the rotor. The rotor then spins, and its electric current interacts with electromagnetic fields that are generated by the stator. The interaction between the rotor and the stator causes the driving force that makes the DC motor spin.In the G8020E12B1-RSR, the rotor is connected directly to the fan blades without the need for a belt or other mechanical linkages. This reduces the amount of friction and wear that can occur over time, resulting in a quieter and longer-lasting fan. The fan also has a low starting voltage requirement, meaning that the motor can start spinning quickly and reach the desired speed quickly.The G8020E12B1-RSR has an integrated over-temperature protection function that is designed to protect the fan from overheating and therefore from damage. It is able to detect temperature changes and slow down or shut down the fan if its temperature exceeds a certain limit. This helps to extend the lifespan of the fan and prevent unnecessary damage.

Conclusion

The G8020E12B1-RSR is a small, compact, and reliable brushless DC fan that is suitable for a wide variety of applications. It features an integrated over-temperature protection system that helps to prevent damage due to overheating, and has a low starting voltage for quick start up and longer lifespan. This makes it an excellent choice for cooling electronics such as laptops, digital cameras, and projectors.
