The topic of electromobility is gaining increasing importance, also in casting technology and the related development of new cast components. Particular attention is being paid to the development and testing of new casting concepts and design methods for the components of electric motors. The demands for a later transferability to series production are constantly being taken into consideration.

At the forefront lies, for example, the embedding of tubes or hollow structures in the housings for electric motors, batteries or power electronics, due to cooling aspects. Furthermore, measures for the optimization of cast rotors are being developed. The concept of the cast coil opens up completely new possibilities for performance increases compared to conventionally wound wire coils. 

Through close interdepartmental cooperation with the Electromobility department, an optimal know-how constellation is being forged that enables a holistic consideration of the manufacturing technological aspects with a casting technological focus, constructive design, and electromagnetic interpretation for the successful manufacture of components for electric drives.
