Material analysis: The materials for electro lamination stacks are constantly being further developed

Electro sheet materials are being further developed and are an important part of a better electric motor. Improved magnetics and easier processing are important goals. It is not only the electro sheet materials that have a major impact on the result, but also the coatings. We work with thinner layers, better electrical insulation, improved heat conduction or double coatings. These are aspects to improve your engine.

Evolution of testing to meet the highest standards from the manufacturer

We have been working with Backlack for almost three decades. While every batch of material used to be tested for adhesive strength, this is no longer necessary today. The test procedures are coordinated and the manufacturer supplies the material certificate.

Continuous expansion of our portfolio

Our portfolio already includes a wide range of suppliers for materials with Backlack coatings. We have tested all of these suppliers in different stages and approved them for production using our processes. We are in close contact with our suppliers in order to play an active role in shaping further developments.

Flexibility in changing suppliers without process changes

The advantage of our technologies is that we can verify new suppliers in the shortest possible time. It is possible to change suppliers that have already been approved from batch to batch without making changes to tools, machines or processes.

Material topics in focus

Verification of the punchability of new materials
Definition of the necessary punching and tooling technology
Development of new technologies for baking and bonding
Validation of the processability of new baking varnishes
Validation of new suppliers of baking varnishes for series production capability and delivery stability
Influence of new baking varnishes on strength, stacking factor, etc.
Analyses on the influence of straightening on the magne defects in the material
analyses of the influence of material properties and production on the final product
