case study

Laser marking a QR code on a motor stator

The client, an electric vehicle manufacturer, wanted to have a high-contrast Data Matrix and plain text marked on its motor stators.
To this end, it needed a laser marking station that could be integrated into its production line.

The challenge

There were two aspects to this challenge:

Laser marking of the Data Matrix and text on the circumference of the engine’s stator by rotating the part.
The surface to be marked is not smooth as the stator is made from hundreds of overlapping silicon steel sheets.
As a result, this involves producing high-quality marking facilitating easy reading on this surface

The SIC MARKING

solution

SIC MARKING provided a fully automatic laser marking station with loading and unloading incorporating a i104 20W laser.

The machine communicates with the client’s production line via Profinet.

Thanks to the vast experience of SIC MARKING’s engineers in the optimisation of laser marking, it was possible to obtain markings with a very high reading rate (>99.99%), despite the complicated implementation conditions.
