How to wind the wires for the external rotor of a brushless motor? How to choose a winding machine?

Is it difficult to wind the outer rotor of a brushless motor? Many of you must have come across it, such as in model aircraft and drone products. Maybe some of you have even taken it apart to wind it yourself. But for factories, if they need to produce in large quantities, manual operation simply won't be sufficient. So how is the winding of the outer rotor of a brushless motor done? How to choose a winding machine? And what are the details requirements? Now, NOYU will simply analyze this for you! Hope it can be helpful to everyone! 
 

In fact, the outer rotor is the stator of a brushless motor. However, many people have come to call it the rotor because they are accustomed to it. This coil part remains stationary. The stator slot is oriented outward. Generally, the wire winding method is the fly-spike method. Depending on the parameters of the stator, the diameter, number of turns, and precision of the enameled wire wound are all different. 
Winding machines usually adopt fly-screw winding machines. Depending on the difficulty of the product and the precision of the wire arrangement, the configuration of the machines varies, and of course, the prices are also different. For example, for the stator of common DJI drones, the wire arrangement is very strict and requires precise wire arrangement; while for some products like fans and massagers, the requirements are slightly lower and an ordinary winding machine can solve the problem. 
The selection of a flyline winding machine is also very important. Generally, it needs to be made from multiple aspects, including the reputation of the manufacturer, the environment, technical conditions, the stability performance of the machine, and after-sales service. If the selection is correct, it will yield twice the result with half the effort; if the selection is not good, it will result in twice the effort with only half the result. 
The common details requirements for flyline winding machines are also numerous. It is necessary to avoid common issues such as wire damage, breakage, and jumping. Whether it is regarding configuration requirements, debugging requirements, or the positioning design of fixtures and tools, all of these are very important. Missing any one aspect is not acceptable.
