  • Name: Sebastian Sieron
  • Age: 30
  • Field: Non-oriented electrical steel research and development
  • Products: PowerCore® 260-27AP, 270-27AP, and 280-30AP

What is non-oriented electrical steel?

Non-oriented electrical steel is a magnetically soft steel that serves as the iron core of electric machines, consolidating the magnetic flux. It boosts motor performance and efficiency in devices ranging from kitchen blenders to wind turbines.


What special features do the new grades of powercore® have?

These new grades have specially tailored structures – they were specifically developed for very high-speed applications. For example, automotive manufacturing customers request the smallest possible high-performance electric motors in order to guarantee the necessary vehicle range. We also successfully reduced further processing influences that had a negative effect on the punching process.

What role do you play in the development process?

I’m responsible for the technical side of product development. I started by conducting all of the operational and lab tests. I then evaluated the results and presented them internally to the Auto team. This team consists of representatives from Application Technology, Technical Customer Support, Sales, and Product Development.

What was the career path that led you to this position?

I studied Electrical Engineering at Bochum University of Applied Sciences, and then I worked at a company in the wind energy industry. I’ve been working for thyssenkrupp’s Steel division here in Bochum, Germany, for four years, in the Research and Development department. I’ve been passionate about science since I was very young, and my current job gives me the opportunity to pursue that passion.

Where will this innovative electrical steel be used?

In widely varying applications. We are selling a flat product – it does not become a component until a later stage. In other words, electrical steel virtually always undergoes further processing. The material that we are currently discussing was primarily developed for very high-speed drives used in vehicle traction, hybrid, and electric drives. As such, it plays a decisive role in making electromobility more sustainable in terms of energy use as well as more environmentally friendly.
