Measuring systems and instruments for process and quality control in the production and processing of magnetic materials

The magnetic properties of stators are a key criterion for the efficiency in electric drives and strongly influence the motor performance and range of electric cars. Important parameters are power loss, permeability and polarisation.

Process-related influences such as punching, packaging and housing strongly affect the magnetic properties. Studies show that the power loss can more than double over the individual process steps from the "electrical sheet to the stator in the housing". This can ultimately lead to e-drives not achieving the required key figures in the "end-of-line test".

BROCKHAUS MESSTECHNIK has developed test systems and sensors with which the magnetic properties can be efficiently and reliably measured in each production step from the sheet material to the stator in the housing.

The measurement data is used to optimise processes and, with the help of inline production control, to sort out possible defective stators at an early stage and thus avoid subsequent costs.

RWTH Aachen – PEM

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

… at RWTH Aachen University was founded in 2014 by "StreetScooter" co-founder Professor Achim Kampker. In ten 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 research group "Electric Drive Production" contributes to the economic, 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 drivetrain 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:

  • Interdependencies between semi-finished product and process in stator production (with special focus on stripping, bending & welding).
  • Development and implementation of application-oriented test and inspection procedures as a basis for demand-oriented products and processes
  • Lifecycle-oriented optimization of production processes and development of measures to identify and reduce the CO2 footprint along the entire value chain
  • Use of AI-based methods for efficient, economical and sustainable electric motor production
