DC Fans - KD1209PTB2 (2) H Application Field and Working Principle

DC fans refers to the fan used in DC circuit; KD1209PTB2 (2) H is a type of axle DC fan produced by Merim Company, with its high-quality performance and reasonable prices pleasing more and more customers. In this article, we will learn about its application field and working principle.

Application Field

The DC fans are mainly used in communication equipment, computers, office, robot, automatic equipments, and intelligent products that require fan functions. KD1209PTB2 (2) H hosts even more application scenarios. With its strong fluid dynamic bearing capacity and low power consumption mode, KD1209PTB2 (2) H is suitable for special environments such as humid, dusty, and highly contaminated places. Such feature allows it to not only ensures the normal operation in all kinds of difficult environments, but also reduce the machine temperature of the system.

Working Principle

The working principle of KD1209PTB2 (2) H is relatively easy. Its internal working principle, as well as all other axle DC fans, can be summarized in following steps: Firstly, the stator holds an electromagnet which creates a rotating magnetic field. Then the two pads of rotor inside the fan rotor also creates magnetic field, which interacts with the rotary magnetic field of the stator to drive the fan impeller to rotate. The rotation of impeller drives the fan movement thus creating airflow. Finally, the rotation speed of fan is determined by the voltage and current changed.

It is important to note that KD1209PTB2 (2) H’s dynamic airflow and pressure is three times higher than most other DC fans thanks to its motorized design. In addition, such high static pressure and air volume allow a longer service life even under high dust and humid environment.

Conclusion

In summary, DC fan - KD1209PTB2 (2) H’s dynamic airflow and pressure is three times higher than the average fan and its excellent performance in fluid dynamic bearing make it suitable for a variety of special environment. It is a reliable yet cost-effective choice for customers who need fan functions.
