Electric Motors-SOLUTION

Electric vehicle motors are designed with hairpin conductors that require several manufacturing steps. Laser ablation, or material removal, enables electric motor manufacturers to rapidly and reliably strip insulation coating from the hairpin ends. Once the underlying copper is exposed, laser welding is a high-speed method of creating low-resistance joints with high accuracy and virtually no spatter.

High-Speed, Automated Hairpin Welding

 

Laser welding creates low-resistance, high-strength joints faster than other welding methods and is easily automated and programmed for different part geometries with no tooling changes or adjustments.

Precise, Repeatable Hairpin Insulation Removal

 

Lasers are fine-tuned to the hairpin application to ensure the rapid removal of thin insulation layers with no damage to the underlying copper. Unlike other removal methods, laser hairpin stripping is a non-contact process that eliminates quality variation concerns caused by abrasive or chemical degradation.
