With numerous partners from industry, the Chair of Production Engineering of E-Mobility Components (PEM) of RWTH Aachen University has achieved the first goal of the “Innovative Materials in Electric Motors” consortium study. To this end, the participants produced a technology demonstrator for stators as the performance-determining component of electric motors, whose components contain innovative materials by using innovative production processes.

“The development and production of a holistic technology demonstrator can offer companies a platform for the targeted presentation of their own solutions,” says PEM Director Professor Achim Kampker. The consortium study is part of the Transformation Hub Scale-up E-Drive project funded by the Federal Ministry for Economic Affairs and Climate Action (BMWK), in which PEM is involved and which aims to support small and medium-sized companies in the technological transition to the production of electric vehicle drives through targeted measures. “Manufacturers with a high level of technological expertise in special applications for combustion engines must not lose touch with the ongoing change,” Kampker says.

Process documentation and preparation of the results

The consortium studyʼs stator demonstrators were produced on the basis of a neutral reference design and include process documentation and preparation of the results. At the end of March 2024, the project was presented to the public for the first time at a special booth at Coiltech, Europeʼs largest electric motor technology trade fair, in Augsburg, Germany. In October 2024, the project will be presented at the renowned Electric Vehicle Production Days (EPT) organized by PEM. In the future, the consortium could also produce a technology demonstrator for rotors.
