Brushless motor stator winding, common winding machine equipment includes inner winding machine and outer winding machine, the main difference is the different direction of the stator slot, so how to correctly use the brushless motor inner winding machine and outer winding machine equipment? What winding machine knowledge and skills do you need to master? Vacuz will introduce it to you!

1. Equipment debugging and parameter setting

1. Mold and tooling matching:

Inner winding machine: Ensure that the mold and stator slot direction and size are accurately matched to avoid collision.

Outer winding machine: Adjust the flying fork angle and stator slot spacing to ensure that the wire is tightly wound.

2. Tension and speed control:

Tension setting: thin wire is controlled at 0.5-1.5N, and thick wire is controlled at 2-5N.

Speed ​​matching: thin wire is recommended to be ≤500rpm, and thick wire is recommended to be ≤300rpm.

‌Program call and debugging‌: Through manual mode debugging, observe whether the mold positioning and wire nozzle movement trajectory are accurate.

2. Operation specification and quality control

‌1. Standardization of operation process‌:

Check before starting: Confirm that the power supply, air source, and control line are connected normally, and the fixture is installed firmly.

Monitoring of winding process: Observe the arrangement of coils on the inner winding machine, and check the movement of the flying fork and the position of the wire on the outer winding machine.

‌Abnormal handling‌: Stop the machine immediately to check the problem when a broken wire or jumper is found.

2. Key points of quality inspection‌:

Inspection after winding: Use salt water test or pinhole tester to check the insulation performance.

Appearance inspection: Confirm that the coil has no scratches, paint peeling, and the height difference of the end meets the requirements.

3. Maintenance and skill improvement

‌1. Daily maintenance‌:

Cleaning and maintenance: Clean the wire nozzle, tensioner, guide rail and other parts.

Lubrication maintenance: Regularly add grease to the lead screw and guide rail.

‌2. Troubleshooting and skill training‌:

Common fault handling: Check the accuracy of the tensioner, the wear of the wire nozzle, and adjust the servo motor parameters, etc.

Skill improvement path: theoretical learning, practical training, participation in equipment upgrades and process optimization.

The above points cover a full range of content from equipment commissioning to maintenance and maintenance, which is of great significance for ensuring the correct use of brushless motor internal winding and external winding equipment. I hope it can help everyone!
