DC fans are a kind of electric fan driven by DC motor. They are usually used in environments where exposure to dust, humidity, vibration, or corrosion may make AC fans unsuitable. 4394M is one of the most popular DC fans currently available. This article will explain its application field and working principle.

Application Field

The 4394M DC fan is a fully-integrated, high-performance brushless dc (BLDC) axial fan. It features an outer rotor type motor, which offers higher efficiency and greater power density than its inner rotor type predecessor. It is designed to provide reliable, low-noise cooling to a variety of electronic systems, from consumer products to industrial electronics. It is also capable of operating in volatile environments, including extreme temperatures, high humidity, dust, and corrosion.

This fan is commonly used in computers, home appliances, and industrial equipment as a cooling system. It can be used to exhaust hot air from a system, or to draw in fresh, cool air to circulate inside the system. 4394M features a wide operating range from 4.2 V to 12 V, and provides excellent thermoelectric performance at very low noise levels.

Working Principle

Like other brushless DC fans, 4394M is powered by an electric motor that is driven by an external power source. The fan has an integrated rotor and stator arrangement, consisting of permanent magnets which spin around a metal sleeve. The rotation of the magnets is directed and maintained by three windings located around the stator, with a hole in the middle allowing the spinning magnets to create a vortex effect.

The electric current produced by the power source is sent through the windings, producing magnetic fields which interact with the magnets in the rotor. This interaction creates a rotational force, causing the rotor to spin and move the surrounding air. This process continually repeats itself as long as electricity is supplied, which results in cooling air flow.

4394M is designed with an efficient air flow system, offering excellent cooling performance while generating very little noise. Its small size and lightweight design makes it suitable for tight spaces, while its wide operating range makes it compatible with a wide range of voltage sources.

Conclusion

4394M DC fans are a reliable, efficient, and cost-effective solution for cooling applications. They offer excellent thermoelectric performance, allowing them to operate in a wide range of environments. Their small size and lightweight design makes them ideal for cramped spaces, while their wide operating range makes them compatible with a wide range of power sources. 4394M is a popular DC fan for use in a variety of computers, home appliances, and industrial equipment.
