RWTH Aachen - PEM

The Chair "Production Engineering of E-Mobility Components" (PEM)

...at RWTH Aachen University was founded in 2014 by "StreetScooter" co-inventor Professor Achim Kampker. In seven research groups, the team is dedicated to all aspects of the development, production and recycling of battery systems and their components as well as the fuel cell and the production of the electric drive train and entire vehicle concepts. The "Electric Drive Production" research group contributes to the economical, variant-flexible, future-oriented and sustainable production of the electric drive and its active components (rotor and stator). The focus is on investigating issues along the entire value chain - from the semi-finished product to the finished drive and from the individual process to the holistic consideration of cross-process interactions. In accordance with the PEM philosophy of the "Innovation Chain", the team works on new and innovative technologies, always keeping an eye on the path to industrial application and solution scaling. Current topics of the research group are:

  • Interactions between semi-finished products and process in stator production (with special focus from stripping, bending & welding).
  • Development and implementation of application-oriented test and inspection procedures as a basis for products and processes that meet requirements
  • Cycle-compatible optimization of production processes and development of measures to identify and reduce the CO² footprint along the entire value chain
