Mannesmann rotor shafts for electric vehicles must be extremely precise – even the slightest variations have a direct impact on efficiency and service life. That is why we are continuously refining our precision steel tubes for rotor shafts in close collaboration with our customers. The key: Hollow shafts instead of solid material. They significantly reduce weight, use material more efficiently, and enable additional features such as integrated internal cooling.
As part of the “Initiative Automotive” – a competence network within the Salzgitter Group – we develop materials and customized lightweight construction solutions for automotive manufacturing.
