DC Fans

DC Fans are devices based on the principles of electromagnetism to produce a breeze of air. They are powered by direct current (DC) which is commonly supplied by a battery or a specialized power supply. The fans offer constant airflow to maintain a particular temperature or to facilitate cooling in electronic equipment.

9A0912G402 Application Field and Working Principle

The 9A0912G402 is a type of DC fan deployed in applications requiring a low level of noise. It has a bearing system and one of its advantages is that it offers a low rotational speed, hence providing quiet operation. The fan, with a diameter of nine centimeters and a width of 12 centimeters, has a maximum airflow rate of 9.39 cubic feet per minute. That said, it is suitable for cooling down a wide range of electrical devices.

The fan is composed of a rotor and a stator. The rotor consists of a hub and blades and is responsible for converting electrical energy into mechanical energy. This rotor is then placed inside the stator, which is composed of a pair of electromagnets set opposite each other. When powered, the rotor experiences a strong electromagnetic field and begins to rotate.

Moreover, the 9A0912G402 is fitted with a control unit, including electric circuitry, which helps maintain the speed of the fan not exceeding the desired level when it is exposed to a high temperature environment. It also enables the fan to adjust its speed to the current temperature and help maintain a certain balance. This allows the fan to comply with certain temperature ranges without having to turn on and off all the time.

In conclusion, the 9A0912G402 DC fan is ideal for use in devices that require low rotational speed and low noise levels. With its bearing system and control unit, the 9A0912G402 is able to keep the temperature of the device within the desired range without much noise.
