DC Fans

DC fans, also known as direct current fans, are motorized fans powered by DC voltage sources. They are used to help circulate air in a wide range of applications and are designed for both commercial and residential use. DC fans have low power consumption, low noise levels, and long life-cycles, making them ideal for a wide variety of applications. DC fans are popular in HVAC systems, automotive cooling systems, and energy efficient homes.

The 9G0948M202 is a DC fan with a brushless DC motor. It is a 120mm axial fan with a 120mm opening, and includes a removable filter for additional filtration. The fan operates on 12V DC and has a rated speed of 1500 RPM, with an airflow of 76.5CFM. The fan is designed with a wide range of features that make it ideal for many applications, such as in computers, servers, sound systems, and other electronic devices.

Application Field

The 9G0948M202 is most commonly used in a range of electronic applications, such as computers, servers, sound systems, and other electronic devices. As a brushless DC fan, it is often used in applications that need a high-airflow fan with low noise, such as in cooling systems and HVAC systems. The design of the fan also makes it suitable for use in energy efficient homes. The fan is also popular as a replacement fan for industrial equipment, as it offers a higher level of performance and lower noise levels than traditional AC fans.

Working Principle

DC fans operate on DC electric power, such as that available from a battery or transformer. The fan motor is typically a brushless DC motor, meaning it consists of an outer loop of stator winding and an inner loop of rotor winding. The stator produces a rotating magnetic field which induces a current in the rotor coils. The rotor coils in turn produce their own magnetic field, which interacts with the stator, causing it to rotate. As the fan rotor rotates, air is drawn in through the fan intake and discharged out of the fan exhaust.
