Fast inspection of hairpin stators
The hairpin stator is an essential component of a modern electric motor. These hairpins are often joined by laser welding to form a winding. The quality of this joining is crucial to the reliability of an electrically powered vehicle. New manufacturing processes, new products and unclear quality requirements pose major challenges for manufacturers. To ensure quality, inspections using CT can make an important contribution. This enables statistical monitoring of the production process, rapid feedback in the case of sudden deviations and support for process adjustments.
The automated evaluation process developed by Microvista allows economical inspection of large quantities. Why?
40 times faster evaluation than manual inspection
Scans with adapted spatial resolution and highly parallel automatic evaluation at rapid speed make it possible to inspect up to 40 stators per day.

3 reasons for the economic testing of large quantities:
- short scan times — made possible by a very fast CT scanner
- fully automatic highly parallelized evaluation
- sorting directly after inspection

Inspection of all hairpins in electric motors
The CT testing method developed by Microvista makes it economically feasible to examine the quality of every hairpin joint. A wide variety of parameters, such as pore volume or different cut surfaces, can be defined as quality parameters. Thus, the automatic evaluation of Microvista offers significantly more information than can be provided by standard tools. In addition to classical analytical methods, subtasks are also solved using machine learning tools.
