For brushless motor stator winding process, the general use of winding machine equipment, common winding machine equipment has internal winding machine and external winding machine, many friends are not very clear about the difference between the two kinds of machines, Vacuz and we introduce it! I hope to help you!

The main difference between internal and external winding machines for brushless motor stators is the winding method and the scope of application.

The inner winding machine is mainly used for stator products with inner groove. The winding mainly adopts needle winding. The needle bar moves with the enameled wire from top to bottom, or from bottom to top. Servo control system, high precision guide rail, screws and other spare parts are often used. This type of winding requires high requirements, high configuration and higher winding precision. It is not only suitable for internal winding products, but also for external winding products. Power tools, garden tools, water pumps, hair dryers, electric toothbrushes and other brushless motor stators are commonly used internal winding equipment.

External winding machine is suitable for stator products with outward slots, mostly in the form of external winding, such as model drones, fascia guns, electric car motor stator and so on. Flying fork winding machine is the common equipment to solve the winding problem. If there is a requirement for precision wiring, then the requirements for the configuration will be higher, and a professional servo system will also be required.

When choosing the winding machine equipment, you need to choose the right equipment according to their respective models and configurations in order to achieve twice the result with half the effort. For example, internal winding equipment has higher requirements and higher configurations than external winding equipment. Therefore, if you have particularly high requirements for precision, you can choose internal winding equipment. For externally wound products, you can also choose internal winding equipment if you do not require high efficiency.

As for the winding details, this needs to be determined according to the specific motor model and requirements. Generally speaking, the winding details include coil arrangement, number of turns, wire diameter, winding direction and so on. These need to be determined according to the specifications and design requirements of the motor.

Overall, the correct selection of winding machine equipment and attention to winding details are critical to the quality and performance of brushless motors.
