DC Fans

CFM-4020V-270-255 is a DC fan designed to provide efficient cooling for various types of electrical radiator, heat sinks and other cooling devices. DC fans are common in the market today, used in the home, commercial, industrial, medical and military sectors. This article will focus on the application field and working principle of CFM-4020V-270-255.

Application Field

CFM-4020V-270-255 is an ideal choice for cooling down a variety of electronic devices including heat radiators, heat sinks, voltage regulators, battery chargers, motor controllers, and power supplies. This fan is perfectly suitable for a wide range of applications where space and temperature are both important. This DC fan is also the reliable choice for many day-to-day applications such as fans, pumps, compressors, drive units, and other small electric motor driven components.

Working Principle

CFM-4020V-270-255 operates with a DC direct current fan motor. It has two main components, the stator and the rotor. The stator is composed of a pair of concentric coils wound around a permanent magnet. The rotor is a series of windings mounted on the fan\'s hub. When a current flows through the stator, an electromagnet is created, which interacts with the permanent magnet to create an electromagnetic field. The rotor then rotates in response to the electromagnetic field, resulting in the movement of air. The air passing through the fan blades is forced outwards, allowing a faster and smoother cooling effect. In addition, the carefully designed motor makes the fan have low noise, high efficiency, long life and reliable operation.

Conclusion

CFM-4020V-270-255 is a high-performance DC fan designed for use in numerous industries. With its strong structure and efficient, powerful motor, it is perfect for heavy-duty applications that require reliable and efficient cooling. It is also relatively quiet and energy efficient, making it a great choice for those looking for an efficient fan with minimal noise.
