Can a high stacking factor be achieved with Backlack? Why is electrical steel important in a motor? What does the stacking factor entail, and how is it calculated? Which variables can influence the stacking factor? You will find all the answers to your questions right here.

From 25 to 26 September, Pordenone was the meeting place once again for experts in the electrical industry to learn more about the most recent innovations. voestalpine focused on the two main areas of e-mobility and Backlack.

Electrify Tomorrow was the motto of the voestalpine presentation at this year's CWIEME in Berlin. As an official sponsor of Formula E, an electric racing car was of course a must as a trade fair highlight. Technical presentations given by experts and new product developments were met with a great deal of interest. Like last year, the crowning finale was the "Austrian Night." This year’s trade fair was again a great success.

Mit backlack-v® + Accelerator wird die Verklebezeit auf ein Minimum reduziert und die Großserien-Produktion von Elektroband ermöglicht. voestalpine liefert die neueste Entwicklung in der Backlack self-bonding system-Technologie mit der High-Speed-Backlack-Innovation für Elektromotoren aller Größen und Bauarten. Neben den bewährten Backlack-Vorteilen wie Designfreiheit und mechanischer Stabilität bietet das neue System gleich eine Reihe weiterer hocheffizienter Qualitäten.

This year's CWIEME once again provides each visitor with an overview of the most interesting technologies and mobility solutions of the future.

Learn surprising new things at the artistic highlight of the exhibition.

Yes, but not always, not at any price and not in every application. Learn how sheet thickness has an effect on motor efficiency as well as on processing efficiency. Also learn about the connection between sheet thickness, the year 2025 and global stamping capacities. Feel the excitement!

Where does the current of opinions flow with respect to electromobility? An interactive presentation at this year's "Connected by Excellence" provided an overview of further developments in electromobility and insights into the opinions of representatives and experts in the industry.

Professor Metin Tolan explains. Electric motors need an iron core. Highly efficient electric motors need and iron core made of individually stacked laminations made of electrical steel. But how are these individual laminations optimally bonded with a perfect fit?

 

The stator and rotor cores of electrical machinery are manufactured using thin laminations stacked together by our customers in order to minimize eddy current losses. There are several ways to join these laminations, and the most efficient way is to use Backlack.

The familiar topics of light-weight design and safety in car bodies will continue to gain significance with increasing electromobility. The need for highly efficient electrical steels for rotors and stators in the drive train is new for many customers. While today more than 100 electric motors are found in every modern car, the manufacture of pre-materials for such motors was less challenging. The new drive motors have changed the picture dramatically. 

Special motor designs developed in the past few years require the use of particularly high-quality electrical steels. In compliance with these market requirements, we have developed a number of innovative electrical steels. We have given special consideration to pure technical requirements as well as to the workability and availability of the materials.
