What are the requirements for the winding machine in the multi-wire internal winding of the motor st

When winding the stator coil of a motor, it can be either single-wire or multi-wire. Single-wire winding is relatively simpler, while multi-wire winding requires more attention and has certain requirements for the machine. So, what are the requirements for the winding machine when winding the motor stator with multiple wires? How can one avoid thread damage and scratches? Now, NOYU will give you a brief introduction!
 

The key requirements for the winding machine of motor stator multi-wire internal winding are as follows:

I. Optimization of slot opening design

During the multi-wire internal winding process of the motor stator, the design of the slot that the guide pins of the winding machine need to pass through is particularly important. When multiple strands of wire are run in parallel, the wire diameter becomes thicker. This requires that the slot design have sufficient width to ensure that the wire harness can pass through smoothly and avoid wire damage or breakage during the winding process. In addition, for multi-wire parallel winding of different wire diameters, the design of the slot also needs to be flexibly adjusted to meet different winding requirements.

Ii. Stator height adaptability

The thickness of the stator stack is a key factor affecting the winding arc and the swing amplitude of the enameled wire. As the height of the stator increases, the winding arc increases accordingly, and the swing amplitude of the enameled wire will also increase accordingly. Therefore, the winding machine needs to be adaptable to stators of different heights to ensure a stable winding effect and precise winding accuracy during the multi-wire concurrent winding process.

Iii. Precision of Tension Control

In the process of winding multiple wires in parallel, the stability of wire feeding is of vital importance. To achieve this goal, a servo tensioner is usually adopted for wire feeding. Tension control must be accurate and stable. The pulling force should neither be too large to avoid breaking the wire harness nor too small to prevent the wires from not being wound tightly. Through reasonable tension control, the quality and efficiency of winding can be effectively improved.

Four. Reasonable control of winding speed

Winding speed is an important factor affecting the quality and efficiency of winding. A too fast winding speed may cause the enameled wire to break or get damaged, while a too slow speed may affect production efficiency. Therefore, it is necessary to adjust the winding speed to a reasonable range based on the performance and user manual of the winding machine to achieve an efficient and stable winding process.

V. Flexibility and Adaptability of Mold Design

As a key component in the winding process, the design of the mold needs to have sufficient flexibility and adaptability. The mold should be capable of flexibly responding to stator products with different parameters or shapes to meet diverse production demands. Meanwhile, the mold design should also leave some leeway to adapt to stator products with small differences in outer diameter and height, thereby enhancing the flexibility and efficiency of production.

Vi. Preventive Measures for Thread Injuries and Scratches

To prevent wire damage and scraping during the multi-wire winding process of the motor stator, a series of preventive measures can be taken. Firstly, by precisely adjusting various parameters of the winding machine, such as slot distance, tension control and winding speed, it can adapt to different winding requirements. Secondly, use appropriate accessories, such as high-precision servo tensioners, to ensure the stability of the wire feeding process. In addition, it is necessary to strictly follow the user manual and operating procedures of the winding machine to avoid wire damage or scratches caused by improper operation. Finally, regular inspection and maintenance of the winding machine to ensure it is in good working condition is also one of the important measures to prevent wire damage and scratches.
 

By implementing the above key requirements and preventive measures, the winding quality and efficiency during the multi-wire internal winding process of the motor stator can be effectively improved, production costs can be reduced, and product competitiveness can be enhanced.
