Rotor shaftswith optimized concentricity

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.

AdvantagesRotor shafts from Mannesmann

More material-efficient

Thanks to hollow shafts made of precision steel tubes

Excellent dimensional and positional tolerances

Meet strict dimensional and positional tolerance requirements even at high speeds (minimal imbalance)

Factory-Fabricated Connections

Longitudinal grooves or spline joints can be incorporated directly during tube manufacturing

Up to 40% lighter

Compared to rotor shafts made of solid material

High Performance

Designed for maximum fatigue strength and long service life

Internal cooling possible,

Unlike solid shafts

Excellent Machinability

Machining, welding, heat treatment, hot and cold forming
