What are the differences between DC DC fans and AC AC fans?

What are the differences between DC DC fans and AC AC fans?
Choose AC fan or DC fan. What is the difference between DC DC fan and AC AC fan? I believe that many people who want to know or buy cooling fans will have this little question. The following cooling fan manufacturer-Ruiapple will analyze the difference between DC DC fan and AC AC fan from different angles, and hope it will help you when choosing a cooling fan.
 
1. Working principle:
The working principle of the DC cooling fan is that through DC voltage and electromagnetic induction, electrical energy is converted into machinery to drive the rotation of the blade. The coil and IC are continuously switched, and the induction magnetic ring drives the rotation of the blade.
 
The working principle of AC fan: It is driven by AC power, and the voltage will alternate between positive and negative. It does not rely on circuit control to generate magnetic field. The frequency of the power supply is fixed, and the changing speed of the magnetic poles generated by the silicon steel sheet is determined by the frequency of the power supply. The higher the frequency, the faster the magnetic field switching speed, and the faster the rotation speed in theory. However, the frequency should not be too fast, too fast will cause difficulty in starting.
 
2. Structure composition:
The rotor of the DC cooling fan includes the fan blades of the DC cooling fan, which are the source of air flow, the fan axis, and are used to support the rotation of the balanced fan blades, the rotor magnetic ring, permanent magnets, and promote the magnetic level switching speed key, the magnetic ring frame, Fixed magnetic ring. In addition, it also includes supporting springs. Through these parts, the whole part and the motor part are fixed for the rotation of the tuberculosis. The direction of rotation is produced, and the active size and the rotation speed are key. Its speed regulating performance is good, and the control is simple.
 
The internal structure of an AC fan is composed of two coil windings, one is the start winding, and these two windings are connected in series to form three points. The series point is the common end, and the start winding end is the start end. The winding end is the operation. In addition, a starting capacitor is required. The capacity is usually between 12uf and the withstand voltage is usually 250v. There are two connectors, one end is connected to the end of the starting winding, and the other is connected to the end of the running winding, forming a triangle, power supply (no need Distinguish between the live wire and the neutral wire) One is connected to the end of the running winding (that is, it is also connected to one end of the capacitor), the other is connected to the common end, and the grounding wire is connected to the motor casing.
 
3. Material characteristics:
Material of DC cooling fan: It is made of alloy material, and the life span can be used continuously for more than 50,000 hours. The internal structure of DC has transformer and main control board (including frequency conversion circuit, rectifier filter, amplifier circuit, etc.), which will not be affected by voltage fluctuations. Long service life. The internal structure of the AC fan is based on a transformer. Most of the materials used for the AC fan use domestic discharge needles, which are generally tungsten needles or stainless steel materials. If the voltage fluctuates too much, the service life of the transformer will be affected.
