Welcome back to our production line! In the last video, we walked you through the first stage of winding and embedding the initial layer of copper coils into the stator. In this video, we’ll continue with the second stage of the process.
After the first layer of copper coils is in place, we manually insert the second layer of insulation paper.
This step is critical. It ensures that the first and second layers of copper coils are properly insulated, preventing any electrical short circuits.
Next, the machine begins the automated winding of the second layer of copper coils. The copper wire is tightly wound into the stator slots with precise control, creating a neat and uniform coil structure.
Once the second layer of copper coils is complete, we move on to inserting the three UVW lead wires.
These lead wires are essential for the motor’s operation—they’re responsible for transmitting the three-phase electrical current into the motor. It’s crucial that these connections are precise and secure to avoid any issues during the motor’s operation.
Finally, the stator undergoes another pressing and shaping process. Using high-precision equipment, the copper coils are firmly secured into the slots to ensure they don’t exceed the design dimensions. This step enhances the mechanical stability of the stator and ensures consistency across the entire production line.
That wraps up the second stage of the process! In the next video, we’ll show you how we secure the coil ends, shape the stator further, and perform the final winding tests. Stay tuned for more!
