"Without Innovation, the Industry Will Shrink"

Franjo Wöstmann, CEO of Cast Coil GmbH, is committed to innovation – specifically in the form of a new type of electric motor that he is developing for series production together with Lenord+Bauer. In this interview, he discusses the importance of European manufacturing, the need for entrepreneurial courage, and his upcoming talk with Christopher Boss at the Sustainable Conference – “From Melting Point to Turning Point.”

Mr Wöstmann, you recently entered into a partnership with Lenord+Bauer to develop an outer rotor electric motor using Cast Coils. What makes this project stand out?

Franjo Wöstmann: On a technical level, the project brings together two companies that combine their respective strengths to create added value and launch a new product. But what is much more important are the people involved and the spirit of the companies that dare to break new ground, combining innovation, entrepreneurship and fun in the process. That’s what defines this project and what will make it a success.

 

Why is it so important that this motor is manufactured entirely in Europe?

Wöstmann: In recent years, supply and process chains have increasingly relied on imports while transferring know-how abroad. That can make sense in terms of cooperative partnerships. However, the much-lauded global sourcing approach, paired with constant price pressure, has led to dependencies that are now putting European supply chains at risk.

If we want an energy transition and sustainable production – not least to safeguard jobs in Europe – we need to act independently while fostering cooperation. That’s why we are consciously focusing the value chain within Europe.

 

The production of the first prototypes is just around the corner. Are you expecting any challenges?

Wöstmann: The motor production process is new territory for both partners, and we’re looking forward to the challenges that come with it. At the moment, we are bringing together the necessary supply chain partners – and we’re encountering broad support.

That said, there will certainly be several hurdles along the way to full implementation, especially due to price pressure from Asia. But we’ll overcome them with new solutions, higher performance and quality, and sustainable manufacturing practices.

Packing density of aluminum coils compared to conventionally wound coils with round copper wire

With Cast Coils, for instance, we are able to replace conventional copper wire windings with aluminium coils produced by die casting. That alone represents a major innovation. At the same time, these aluminium coils can be produced and recycled sustainably, and they enable new motor designs with higher performance and improved efficiency. 

Innovation ‘Made in Germany’!

 

Part of your presentation will also cover transferable solutions for other industries. In your view, which lessons from the die-casting sector are particularly relevant?

Wöstmann: In recent years, it has become clear that diversifying across multiple application sectors and reducing dependency on the automotive industry makes good business sense.

However, in addition to sales and strategic orientation, continuous improvement of internal processes is equally important. For foundries – as energy-intensive operations – early procurement of energy and, where possible, self-sufficiency have proven increasingly vital. These are the topics that will be further discussed in the presentation with Christopher Boss.

 

Looking ahead five years: what needs to happen for you to say – we have truly reached a turning point as an industry?

Wöstmann: I could now start raving about technology, innovation and sustainability – and they are indeed the enablers. But they’re not the first steps. All the necessary elements are already there, but we are being held back by a lack of planning certainty and entrepreneurial spirit. 

In other words: we need clear, long-term policies and supportive conditions to enable investment – and we need decision-makers who are willing to take on the role of entrepreneurs.
