Innovative manufacturing solutions for 48V Mild-Hybrid-Systems

With the help of 48V technology, the well-known "alternator" becomes a powerful starter generator that supports the combustion engine as an auxiliary unit. This type of hybridization has become known as mild hybridization.

Belt starter generators (BSG) and gear-integrated starter generators (ISG) have established themselves as types. In the meantime, both are preferably realized in plug-in coil technology, so-called hairpins.

Aumann has know-how in the entire process chain for stators, rotors and ready-to-install complete systems of this type of hybridization.

We combine the wide range of forming, winding, contacting and assembly processes with a needs-based degree of automation to create the optimum manufacturing solution.
