DC fans (PMD1208PKB1-A.(2).GN) are a widely used type of electrical fan, which employs a two-phase brushless DC electric motor to drive air through a system of ductwork. The design of this fan offers a unique combination of power, airflow, and efficiency; allowing for a smaller footprint and superior performance.

Application Field of DC Fans

DC fans, including PMD1208PKB1-A.(2).GN, have applications in many situations, especially when low noise, air flow, and efficiency are important factors. They are used in home and industrial settings as cooling fans, in medical equipment, computer and server rooms, and in aerospace and military applications. These fans are often used in conjunction with heat sinks to better dissipate heat.

Working Principle of DC Fans

The working principle of DC fans, such as PMD1208PKB1-A.(2).GN, is based on Newton\'s Third Law of Motion, which states that for every action, there is an equal and opposite reaction. The fan blades create a force on the air molecules that pushes them back and away from the blades. As the fan rotates, the air molecules are pushed away from one side of the fan and pulled in from the other side, creating a movement of air. This movement of air is known as airflow.

In the case of DC fans, the motor used to drive the fan blades operates on DC electricity. The rotor of the motor is two-phase brushless, meaning that it contains two sets of magnets, each set consisting of two poles. The rotor also has two coils wrapped around it. When the electric current passes through the coils, it creates an electromagnetic field that interacts with the sets of magnets, causing the rotor to rotate. As the rotor rotates, the fan blades spin, and the motion of the blades causes the air molecules to be pushed away from the blades, creating an airflow.

DC fans, such as the PMD1208PKB1-A.(2).GN, provide a great balance between power, airflow, and efficiency. They are durable and reliable, as well as safe for use in home and industrial settings. This makes them ideal for use in applications where a combination of low noise, air flow, and efficiency are important.
