Schuler presents new blanking press at TechDay

Schuler presented its new high-speed blanking press Smartline EV 3.8 for the production of interlocked motor core at its headquarters in Göppingen, Germany.

At its headquarters in Göppingen, Germany, Schuler recently presented its new high-speed blanking press Smartline EV 3.8 for the production of interlocked motor cores, which will be delivered to the German company Waasner, and other systems for the era of e-mobility. More than 50 people took part in this TechDay E-Mobility event, which highlighted the future of electric vehicles.

Schuler’s Rainer Berkefeld pointed out to attendees that China will manufacture 6.8 million electric cars by 2021, referencing a study published by fka and Roland Berger. China already has a quota for electric vehicles of 8 percent since last year; a long-term goal of 100 percent is being discussed. Germany, the Netherlands, and Norway are considering a 100 percent quota by 2030, and France wants to ban the sale of petrol and diesel cars by 2040.

To increase the efficiency of the motors, the geometrics of the electric motor lamination have become more complex, and the dies are getting longer. The new Smartline press has a length of 3.7 m instead of 2.7 m and can process a strip width of up to 630 mm.

At the same time, the material thickness has been reduced. “Analyzing the new requests of the automotive industry with regards to e-mobility, the lamination thickness is currently defined at a range of 0.25 mm up to 0.275 mm.” To meet the challenge of the perfect positioning and repeat slide accuracy required by this development, Schuler developed penetration depth control (PDC). The Smartline series can adjust the PDC at a deviation of 0.01 mm through the stroke range.
