The stable operation of the motor stator winding machine requires not only excellent configurations such as motors and controllers, but also certain requirements for various spare parts including screws, guide rails, cylinders, etc. So what are the specific requirements and how to choose a suitable manufacturer? Vacuz will introduce it to you! I hope it can help you!

1. Core component requirements

As a high-precision device, the motor stator winding machine’s core components, screws, guide rails, and cylinders must meet specific requirements to ensure the stability and accuracy of the winding process.

‌1. Screw requirements‌

Precision and load capacity: A high-precision ball screw must be selected, and the lead error should be controlled at ≤±0.01mm/m to ensure the accuracy of the wire nozzle movement during the winding process. The rated dynamic load must be more than twice the actual load to cope with the impact force during high-speed movement.

Material and life: Alloy steel is preferred, and the surface is chrome-plated to prevent rust, with an expected life of more than 5 years. Although stainless steel guides are corrosion-resistant, they are more expensive and suitable for special environments.

2. Guide rail requirements

Parallelism and rigidity: When installing dual guide rails, the parallelism must be ≤0.02mm/m to avoid the slider from getting stuck or jittering during operation, which will affect the winding accuracy. The preload level needs to be selected according to the load. Light preload (P0) is suitable for low-vibration scenarios, and heavy preload (P2) is suitable for high-speed or high-vibration scenarios.

Speed and accuracy: The linear motor guide rail speed can reach more than 5m/s, the acceleration exceeds 10G, and the positioning accuracy can reach ±1μm, which is suitable for high-precision applications such as semiconductor equipment. However, it should be noted that high-precision encoders are required for high costs.

‌3. Cylinder requirements

Brand and series: Prioritize cylinders with higher cost-effectiveness, with a service life of more than 3 years.

Cylinder diameter and stroke: The cylinder diameter needs to be calculated and determined based on the load and air pressure, and the stroke needs to match the actuator movement distance to avoid being too long to cause inefficiency or too short to complete the task.

2. Methods for selecting suitable manufacturers

When selecting a winding machine manufacturer, it is necessary to comprehensively evaluate its technical strength, production capacity and after-sales service to ensure that the equipment performance matches the production needs.

‌1. Technical strength verification‌

Core configuration: Confirm whether the manufacturer uses imported or high-end brand components (such as servo motors, drivers, screws, guide rails), and the servo motor must support microstep mode (the higher the subdivision multiple, the better) to improve low-speed smoothness and resonance effect.

Check whether the equipment is equipped with a high-precision tensioner, and the tension fluctuation must be controlled within ±0.5N to avoid wire breakage or coil loosening.

Customization capability: Evaluate whether the manufacturer can customize the mold and winding process according to the stator structure (such as slot direction, outer diameter, inner diameter).

‌2. Production capacity evaluation‌

Number of workstations and efficiency: Select the number of workstations according to the production scale, confirm whether the manufacturer can provide multi-wire parallel winding function, and ensure the coil filling rate.

Stability test: Require the manufacturer to provide a full winding commissioning report to verify the wire breakage rate and coil consistency of the equipment when running at high speed.

3. After-sales service inspection

Response speed: give priority to manufacturers that provide 24-hour technical support to ensure quick response and problem solving when equipment fails.

Training and maintenance: confirm whether the manufacturer provides operation training and regular maintenance services to extend the life of the equipment.

In summary, the core components of the motor stator winding machine must meet the requirements of high accuracy, high stability and long life. When choosing a manufacturer, it is necessary to comprehensively consider multiple factors such as technical strength, production capacity and after-sales service. Through strict screening and evaluation, choosing a winding machine manufacturer that suits your needs will help improve production efficiency and product quality.
