9GV0812H1011

DC fans have become increasingly popular in the past decade due to their wide application range, especially in computer applications such as cooling. The 9GV0812H1011 DC fan is a popular choice in this arena. It is designed to be a medium/low speed big size fan capable of supplying airflow of a capacity of up to 146CFM. This fan is available in 12, 24, and 48V versions.

Before we explore the application field and working principle of 9GV0812H1011, let us understand what is a DC fan. DC fan is a type of fan driven by direct current (DC) power, or batteries. Unlike AC powered fan motors, DC fan motors require no additional electronics or switches to turn them on or off. They can be switched on and off directly by the voltage applied to them. This makes them intuitive and reliable. Additionally, since they are powered by DC current, they draw much less power than an equivalent AC powered fan. DC fans are silent and ideal for applications such as computer cooling and household appliances.

The 9GV0812H1011 DC fan is most suitable for applications that demand large airflow at medium/low speeds. It is a highly reliable fan and has an MTTF(Mean Time To Fail) rating of 250,000 hours. It has an operating temperature range of -10°C to + 70°C and its safety approval UL, CUR, TUV and CE listed.

The application field of 9GV0812H1011 DC fan is quite large. It is ideally suited for usage in industrial machinery and equipment such as presses, grinders, lathes, etc. Moreover, it is also suitable for use in audio equipment, household appliances, LED lighting, telecom servers, air conditioners, and automotive cooling systems. The fan provides low noise and high static pressure, ensuring that it is well suited for high recentering requirements.

Let us now take a look at the working principle of 9GV0812H1011. This fan is driven by a DC brushless motor, meaning that it operates without brushes and uses an internal commutation system to control the rotation. This brushless motor consists of three parts: the stator, the rotor, and the magnets. The stator is the stationary part of the motor that generates the rotating magnetic field. The rotor is the part that rotates and contains the magnets. The magnets interact with the stator’s rotating field to cause rotation. The speed of the fan can be adjusted by changing the voltage applied to it. In addition, the fan also contains a thermostat in order to shut it off once the desired temperature is reached.

In summary, the 9GV0812H1011 DC fan is a highly reliable fan that is designed to provide large airflow at medium/low speeds. It has a wide application range, and is suitable for usage in industrial machinery, audio equipment, and household appliances. It is driven by a brushless DC motor which is controlled by an internal commutation system. This fan is a perfect choice for applications that require both low noise and high static pressure.
