AC motor
At present, the fan products produced by domestic and foreign manufacturers mainly use AC motors.
Advantage:
1. It can greatly reduce the cost, so the product price is lower.
2. The market popularity is higher, and the market for fans using AC motors is estimated to account for 70%-80%.
3. The air volume is larger than that of a DC fan.
The cooling fan is a new type of mechatronics fan that uses the principle of electromagnetic induction, uses a Hall induction component as a synchronous detection device, controls a group of circuits, switches the winding power sequence, generates a rotating magnetic field, and realizes electronic commutation. The cooling fan has a wide range of speed regulation, light weight, environmental protection and energy saving, controllability, reliability, environmental tolerance and economy. It has obvious advantages, and it gradually replaces other types of motors in fields that require high performance, and takes the lead. status. 
  The cooling fan uses direct current to provide power for it. A DC motor consists of two parts: a stator and a rotor. The stator has magnetic poles (winding type or permanent magnet type), while the rotor has windings. After the staff energizes it, a magnetic field (magnetic pole) is also formed on the rotor. There is an angle between the stator and the rotor. The mutual attraction of the magnetic field (between the N pole and the S pole) causes the motor to rotate.
  The cooling fan technicians told us that by changing the position of the brushes, the angle between the stator and rotor poles can be changed (assuming that the angle between the stator poles is the starting edge, and the rotor poles are on the other side, and the rotor poles point to the stator poles. The direction is the direction of the rotation direction of the motor. After this operation, the rotation direction of the motor can be changed.
