The project “Concept ELV² - research on an innovative and efficient e-axle concept” is carried out in cooperation with Daimler AG and the RWTH Institutes Institute for Automotive Engineering (ika), Laboratory for Machine Tools and Production Engineering (WZL) and Institute of Electrical Machines (IEM). Within the project, an innovative electric drive train for heavy-duty distribution transport will be developed. The research focus of the IEM is on the electromagnetic, mechanical and thermal design of traction machines under the special requirements of the truck sector. A highly utilized induction machine is developed using innovative cooling concepts. Further, structural dynamic investigations are in the focus of the project. A prototype of the machine is built up. Measurements on machine test benches as well as system test benches with the entire e-axle are carried out within the project. The project is funded by the Federal Ministry of Economics and Energy (BMWi funding number: 01MY17002B).
