What kind of winding machine should be used for the stator of the brushless motor of the cooling fan

With the continuous development of technology, cooling fans have become increasingly high-tech. Various fans using brushless motors have emerged. Compared with the previous brushed fans, their performance has been improved in all aspects and are highly favored by customers.
 

As an important power component of cooling fans, brushless motors play a crucial role. The winding of the stator coil is related to the quality of the brushless motor. Therefore, how to wind the coil? How to wind it well becomes very important. Then, how to wind the stator of the cooling fan motor?

Generally speaking, the common brushless motor cooling fans have more outwardly-oriented slot openings, with 4-slot and 6-slot types. The outer diameters are not very large. The stator coils of computer and handheld fan motors are very small, only about 10-15 millimeters, with a wire diameter of about 0.1 mm. Ordinary fly-screw winding equipment can be used to solve the winding problem. Four-position or six-position equipment can be selected. The winding speed is relatively high.

There are also inner-wound fan stators with inwardly-oriented slot openings, such as automotive cooling fans and industrial fan stators. The coils are usually several thousand turns, and the inner-wound machine equipment is often used to solve the winding problem. Four-position or six-position equipment can be selected. The winding speed is fast.

Winding precautions:

1. The speed should not be too fast. Exceeding the allowable range of the equipment, the original wire is already relatively thin and prone to breakage and injury.

2. The tensioner should be set properly. It should not be too tight or too loose. Otherwise, it is easy to break the wire.

3. The machine must be manually debugged and the program set first.
 

These are the methods and precautions for winding the stator of the brushless motor of cooling fan. Mastering these basic knowledge and choosing the appropriate winding equipment can ensure a worry-free winding production!
