One way electric vehicle motors differ from traditional vehicle motors is the use of hairpin conductors which require new manufacturing steps to produce. Laser ablation and laser welding enables electric motor manufacturers to both strip the insulation coating from the hairpin ends and to rapidly create precise welded joints with low resistance from the exposed copper.
Contact an E-Mobility expert to learn more about how IPG laser solutions can optimize your electric motor production.
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 ablation methods, laser hairpin stripping is a non-contact process that eliminates quality variation concerns caused by abrasive or chemical degradation.
IPG partners with E-Mobility manufacturers throughout the entire production process from research and development to full-scale manufacturing.
