What is inter-layer short circuit?
The insulation material of the coil (such as enameled wire) may have defects such as air pockets, cracks, or thinning during the production process.
During the winding process, the coil may be scratched during the assembly and riveting stages, leading to insulation damage or perforation.
Over time, the insulation material may degrade, be affected by moisture, or experience other aging effects, leading to a decline in its insulation performance.
Why is inter-layer short circuit testing necessary?
An inter-layer short circuit may cause motor burnout, transformer failure, and other issues.
Detecting and eliminating inter-layer short circuits during the production process helps prevent defective components from being assembled into the final product, reducing the time and cost of disassembly and repair.
It can extend the product's lifespan, improve reliability, and reduce customer complaints and repair costs.
