DC Fans, which are popularly recognized, are widely applied in the industry and are now available in two varieties: 8414G and 8415G. They both have unique functions and differences, and this article will discuss their applications and working principles.

8414G Application Field

The 8414G type is one of the most commonly used DC fans available in today’s market. It is characterized by a dual voltage motor, capable of functioning both at 12V DC and 24V DC. Furthermore, this type of fan is also highly efficient in terms of its noise levels and airflow capabilities. As a result, they are well suited for use in the cooling and ventilation of internal computer components, servers, and datacenters.

The 8414G DC fan is also highly reliable due to the low operating temperature of its motor. As such, it is especially suitable for use in areas where heat is common. Additionally, its electrical noise reduction function allows for silent operation, creating a quieter working environment. For example, it can be used in areas such as libraries, museums, or exhibition halls where noise reduction is essential.

8414G Working Principle

The 8414G DC fan utilizes the principle of radial ventilation for its operation. In this type of fan, the fan is driven by a dual voltage motor, either 12V DC or 24V DC. The motor turns a series of fan blades which generate a centrifugal force. This force then creates a high-pressure zone near the axis of rotation and a low-pressure zone away from the axis of rotation. This difference in the pressure gradient causes an air movement through the fan, thus cooling the surrounding area.

In addition to the radial ventilation principle, the 8414G DC fan also utilizes an internal High Torque (HT) motor for enhanced efficiency. It is composed of a stator and an armature, which are connected by two insulated wires in a continuous loop. The stator is composed of copper coils wound on a steel frame, while the armature consists of copper coils wound on a laminated core. The two components are connected to a single DC power supply, which supplies the necessary voltage for the operation of the fan.

The High Torque motor of the 8414G DC fan operates by producing a rotating magnetic field that interacts with the magnetic field of the armature. This process generates a torque that causes the armature to spin, thus allowing the fan blades to rotate at a speed commensurate with the input voltage.

The 8414G is characterized by its low operating temperature, electrical noise reduction, and high efficiency. All these factors make it ideal for use in applications such as cooling and ventilation. Additionally, the 8414G type is also highly versatile, being able to function with a variety of input voltage levels and speeds.
