TRUMPF powertrain application stator

Laser welding drive components for electromobility

One of the core drive components is the electric motor. Our highly integrated and scalable copper welding processes are already industry standard and play a decisive role in the quality of the contacting, thereby achieving the maximum possible range for the vehicle. Electrified drives have the advantage that the torque is available almost immediately. However, this does mean that the drive components must be able to withstand higher dynamic demands. For this reason, laser processes for high-tensile materials are an absolute must during production. TRUMPF advises its customers on planned applications of all drive components and checks concrete application cases. Our lasers offer the precision and productivity required – even for high quantities. No matter which assembly it is – a differential, hairpin, busbar, rotor shaft, gear wheel, stator or its housing – laser processing makes the more compact design of electric drives possible in the first place.

Applications in the powertrain sector

Complete TRUMPF solutions for the powertrain

Image processing for cutting and welding applications
VisionLine for characteristics recognition

You avoid defective parts with VisionLine. The image processing detects preprogrammed structures on the component and can therefore optimize the welding process in an automated manner. This increases the throughput time and reduces rejects at the same time.

TruLaser Cell 3000, unique and universal
TruLaser Cell 3000 with VisionLine and welding depth sensor system

Benefit from our complete package for optimized welding of components with continuous quality check. Sampling is obsolete as rejects are detected immediately. At the same time, you are taking advantage of optimum process monitoring as well as continuous documentation and traceability.

TRUMPF OCT image processing
OCT characteristics recognition

In addition to VisionLine image processing, three-dimensional contour measurement is also possible. This means you can follow the height difference accurately as well. At the same time, the welds of the hairpin pairs can be measured exactly during hairpin welding.

TRUMPF laser application hairpin welding with visionline
BrightLine Weld for hairpin welding

Our BrightLine Weld technology scores highly not only due to a higher feed rate, but it also makes it possible to weld copper with reduced pores and spatter. This means you benefit from less reworking on the component with less contamination in the machine itself at the same time. You also reduce maintenance times, while actively increasing the active operating time.

EasyModel AI for laser welding

Expand the VisionLine Detect options with EasyModel AI. The cloud-based AI training platform makes it possible to achieve good results without programming knowledge and with little training data. This allows you to train image-based AI models precisely to your requirements and your component.

Laser marking with TRUMPF products
Seamless and continuous documentation

The TRUMPF Quality Data Storage records process data and stores it in flexible storage locations to automate your data quality assurance. For seamless traceability, you can assign the applicable relevant process data from the laser, the optics or other process sensors to each component.
