DC Fans

DC fans are electric motors powered by direct current. They are designed to move air or create a directional draft inside of electric and electronic products to provide cooling. The ASFN10391 is a DC fan with a unique design that allows it to be used in a variety of applications. As with other DC motors, understanding the working principle and the application field are key to using the ASFN10391 properly.

Application Field

The ASFN10391 DC fan is designed to be a low-noise, low-speed fan. It is generally used in electronic applications that require cooling, such as air conditioners, refrigerators, and other cooling systems. Additionally, it can also be used in computer systems, telecommunications equipment, stereo sound systems, and other electronics. It is also suitable for use in automotive systems, such as in fuel-injected systems or engine compartments.

Working Principle

The working principle of the ASFN10391 is based on a direct current electromagnetism. When DC voltage is applied to the fan’s coils, a magnet flux is generated. This flux interacts with the fan’s stationary magnets, causing the rotor to rotate. The rotation of the rotor causes the fan blades to rotate, generating a directional draft or airflow. The amount of airflow is proportional to the applied voltage. As the voltage is increased, the speed and airflow of the fan are increased.

The ASFN10391 is also equipped with a safety switch that automatically senses the temperature of the airflow. When the airflow temperature exceeds a certain threshold, the safety switch trips and shuts off power to the fan, thus reducing the possibility of an electrical fire or other safety hazard.

Conclusion

The ASFN10391 DC fan is a versatile means of providing cooling in electronic and automotive applications. Its low-noise, low-speed operation and built-in safety switch make it an excellent choice for applications where noise might be a concern. However, understanding the working principle and the application field for the fan is essential for proper operation and safety.
