What kind of winding machine equipment is used for the stator of the UAV motor?

Drones are often equipped with professional brushless motors, and there are various models available. There are also specialized winding equipment for winding the coils. So, how is the stator winding of the drone motor carried out? And how can the winding quality be ensured to meet the requirements? Let's take a look! 
 

Generally speaking, the stator winding of drone motors mostly adopts the flywheel winding method, especially for the external rotor brushless motors. Since the slots are outward, this winding method is quite suitable. The flywheel winding machine uses the high-speed rotation of the flywheel and the interaction between the die head, die shell, guard plate, stator rod, etc., to wind the enameled wire inside the stator slots. After completing one slot, continue to wind the corresponding slots until all slots are wound. 
To ensure that the winding quality meets the requirements, the following measures can be taken: 
1.Select the appropriate winding equipment: Based on the specific requirements of the drone and the type of stator, choose the appropriate flywheel winding machine. For drones with higher requirements, such as DJI, special precision wiring and flywheel equipment may be needed to ensure the accuracy and quality of the winding process. 
2. Carefully design the winding and wiring methods: Before designing the winding, it is essential to design the wiring and wiring-out methods properly, making the circuit clear and simple, facilitating the cutting and connection of wires, thereby reducing errors and confusion during the winding process. 
3. Carefully debug the equipment: During the winding process and the debugging stage, be cautious to prevent issues such as wire damage, breakage, or overlapping of wires. In case of any abnormalities, handle them promptly or contact the manufacturer for assistance. 
4. Strictly control the winding speed: Although the flywheel winding machine can enhance production efficiency, in order to ensure the winding quality, especially for precise winding, the winding speed should not be too fast to avoid damaging the enameled wire or affecting the winding effect. 
5. Conduct salt water test: To ensure the quality of the stator windings, a stator salt water test is also necessary. By conducting the test in salt water, you can ensure that your product meets the requirements and avoid performance degradation or damage caused by winding issues. 
 

What method is used for winding the stator coils of the drone motor? How to ensure that the winding quality meets the requirements? The above has been briefly explained. By choosing the appropriate winding equipment, carefully designing the wiring method, carefully debugging the equipment, controlling the winding speed, and conducting salt water tests, the quality of the stator windings of the unmanned aerial vehicle motor can be guaranteed to meet the requirements. This will help improve the performance stability and service life of the unmanned aerial vehicle.
