What are the requirements for the stator precision winding and threading machine?

The winding of the motor stator coils is not just about wrapping the wires; it often requires precise and orderly arrangement of the wires, which is known as precise wire arrangement. If the arrangement is neat and orderly, then what are the requirements for precise winding and arranging the stator coils? What should be done if the wire arrangement is not neat? Let's give a simple introduction by NOYU below, hoping it can be helpful to everyone!
 

1. During the precise winding of the stator coils, the requirements for wire arrangement are crucial. First of all, the winding machine needs to be equipped with precise guide rails, ball screws, and high-precision sensors to ensure that the position and spacing of the wire arrangement can be accurately controlled. In addition, tension control is also an indispensable part. The winding machine should be equipped with a system that can automatically adjust the tension according to the material of the wire, the wire diameter, and the winding speed, keeping the tension within an appropriate range, neither too tight nor too loose.

2. The wire arrangement speed also needs to be carefully adjusted. The winding machine should have adjustable wire arrangement speed and maintain stable operation at low speeds. At the same time, the matching of the spindle speed and the wire arrangement speed is also crucial to ensure the uniformity of the winding. In addition, the stator parameters such as outer diameter, inner diameter, height, multi-wire parallel winding, wire diameter, etc. must meet the requirements to support precise wire arrangement.

3. In terms of molds and devices, positioning needs to be accurate and stable. The needle rods or flywheels must meet quality requirements, and the machining of the molds needs to be careful to avoid burrs and protrusions that affect the wire arrangement effect. Finally, the winding and line passing methods should be simplified as much as possible to save the enameled wire and ensure better winding.

‌Methods to deal with unneat wire arrangement during precise stator winding:

1. When facing the problem of unneat wire arrangement during precise stator winding, we can solve it from multiple aspects. First, check whether the equipment configuration is precise and meets the requirements, such as servo motor drive, controller, guide rails, screws, couplings, etc. If there are components that do not meet the requirements, they need to be replaced with more precise parts.

2. Improving machine stability is key. The stability of the base and frame should be good, and the material and process should meet the requirements. If the machine stability is poor, better material combinations need to be selected to ensure the stability of the base and no shaking or shaking during high-speed operation.

3. Adjustment of the tensioner is also important. It is necessary to check whether the setting range of the tensioner is correct and adjust it to the appropriate position according to the material of the wire, the wire diameter, and the winding speed to ensure balanced tension. In addition, the technical level of the debugging personnel also needs to be up to standard, with rich experience. If the technical level of the debugging personnel is not up to standard or lacks experience, they need to receive training to improve their skills.

4. Improving the precision of molds and stator cores is also an important means to solve the wire arrangement problem. It is necessary to ensure that the stator core, frame, and molds have sufficient precision to avoid wire arrangement problems caused by insufficient precision. Finally, adjust the winding speed appropriately according to the wire diameter to ensure precise wire arrangement while maintaining production output. If the machine runs too fast, the speed can be appropriately reduced to improve the wire arrangement effect.
 

By properly configuring equipment, improving machine stability, adjusting the tensioner, training debugging personnel, improving the precision of molds and stator cores, and adjusting the winding speed, we can effectively improve the quality and efficiency of precise stator winding wire arrangement.
