In life, we can often see the operation of the fan, but many friends do not know what is the principle of the fan? As a professional cooling fan manufacturer, today I will give you a brief introduction.
AC fan operation principle:
First we need to understand the difference between AC fans and DC fans. In the former, the power supply is AC, and the power supply voltage will alternate between positive and negative. Unlike the DC fan, the power supply voltage is fixed, and it must rely on circuit control to make the two sets of coils work in turn to generate different magnetic fields.
In addition, the AC fan has a fixed power frequency, so the changing speed of the magnetic pole generated by the silicon steel sheet is determined by the power frequency. Same principle. However, the frequency can not be too fast, too fast will cause activation difficulties.
DC fan operation principle:
According to Ampere's right-hand rule, a conductor passes through a current, and a magnetic field will be generated around it. If the conductor is placed in another fixed magnetic field, attraction or repulsion will be generated, causing the object to move. Inside the fan blade of the DC fan, a rubber magnet pre-filled with magnetism is attached. Surrounding the silicon steel sheet, the shaft is wound with two sets of coils, and the Hall induction component is used as a synchronous detection device to control a set of circuits, which make the two sets of coils wound around the shaft work in turn. The silicon steel sheet produces different magnetic poles, and the magnetic poles and the rubber magnets produce attraction and repulsion.
When the suction and repulsion force is greater than the static friction force of the lice fan, the fan blade rotates naturally. Since the Hall sensing element provides a synchronizing signal, the fan blade can continue to run, and its running direction can be determined according to Fleming's right-hand rule.
The above is the principle of the fan that the cooling fan manufacturer wants to explain. If you still have any questions, please feel free to contact us. After that, the cooling fan manufacturer reminds everyone that a good fan mainly examines the air volume, speed, noise, service life, and use. What kind of fan blade bearing, etc., so if you want to buy a good fan, you must understand the above knowledge points.
