DC axial fans are very versatile, that is, the airflow in the same direction as the axis of the blades, such as electric fans, air conditioners, and external fans are fans that operate in axial flow. At present, the voltage of the fan we produce is DC voltage, and a fixed electronic switch (such as Hall IC) is used to replace the brush, and the current switch is implemented to drive the rotor to continue to run. It is called a "DC brushless fan", also called "DC axial fan". Xingdong mainly has 5v, 12v, 24v, 48v and other DC axial fans.

What is the working principle of DC Axial fans?
Where can DC axial fans be used?
There are many kinds of motors. Those related to our DC motors are divided into brushed motors and brushless motors. The mechanism of a motor can be divided into two parts: the stator and the rotor. The stator produces a changing magnetic field and the rotor is a fixed magnetic field. The motor is driven by the co-polar repulsive force of the magnetic field. Once the rotor is rotating, the magnetic field will definitely be different from the original stator; therefore, there must be a magnetic field reversal. Otherwise, if the motor turns, it will be sucked to a halt. Brush motors rely on brushes to commutate. If the brushes are worn out, the motor can't carry the load. Therefore, the brushes are made of very delicate materials, before the common use of carbon brushes (cheaper); then there are silver or palladium brushes. But the brush motor commutation, there is hard contact, will generate static electricity and sparks; there is a great danger. Therefore, the scope of use is limited. The brushless motor relies on changing the direction of the current to commutate, which is a suspended commutation without hard contact; therefore, it is very safe, less noisy, and has a long life (about ten times the life of a brushed motor). DC brushless motors have a wide speed range, from 1,000 rpm to 10,000 rpm. The maximum speed of AC shaded-pole motors is 3000 rpm (at 60 Hz).
DC axial fans can be used for ventilation or heat dissipation in metallurgy, chemical industry, light industry, food, medical equipment, mechanical equipment, and civil buildings. If the casing is removed, it can also be used as a free fan, or it can be used in longer The exhaust pipes are installed in series at intervals to increase the wind pressure in the pipes.
Features of DC axial fans:
Small DC axial fans: It has the characteristics of low power consumption, fast heat dissipation, low noise, energy-saving, and environmental protection. Because of its small size, it is widely used.
Large-scale DC axial fans: It has the characteristics of simple structure, stability and reliability, low noise, large air volume, and a wide range of functions.
Dongguan Xingdong Electronics Co., Ltd has developed a variety of differentDC axial fans and conducted a large number of tests before leaving the factory to ensure the quality. If you are in the DC axial fans business, you can consider using our cost-effective products.
