Compared to traditional fans, brushless motors are now gradually replacing brushed motors, and the technology is becoming more and more advanced. The application of cooling fans can be said to be relatively wide, such as common computer fans, exhaust fans, bullhorn fans, floor fans, large industrial fans, automotive fans, etc.

Cooling fan motor

Speaking of cooling fans, of course, we must understand its DC brushless motor stator, stator coil winding is an important process, if not well wound, it may affect the subsequent use of the effect.

Cooling fan DC brushless motor stator is generally divided into two kinds:

One is the outer winding of the stator, the slot outward, the common is 4 slot stator, according to demand, the size varies, the number of turns of the coil is also different, there is a 6-slot stator, generally using the flying fork winding method, as the fan stator is mostly fine wire, wire diameter of about 0.1mm, the need to wind more turns, and then the small fan stator is cheaper, so the winding equipment needs to be multi-station high-speed winding to improve winding efficiency.

The other is the internal winding of the stator, the slot inward, the common is the 4 slot stator, need to wind many turns, some even reach more than 3000 turns, generally using the needle winding method, available four or six stations internal winding machine to improve production efficiency.

Whether it is a flying fork winding method or needle winding method, cooling fan DC brushless motor stator winding, winding equipment must be well debugged to avoid injury, broken lines, etc., the size of the tension to control, good stator detection, to ensure compliance with the requirements.
