DOING MORE WITH LESS

Due to increasing energy demands, we need to ensure energy security: Wind turbines need higher power ratings without growing bigger:
Components must remain transportable to access further installation areas.
The nacelle’s weight needs to be low to avoid massive foundations.

ONE CONCEPT – INDIVIDUAL SOLUTIONS:
A TECHNOLOGY PACKAGE FOR YOUR NEEDS

Our development method involves scenario calculations to identify future bottlenecks. Targeted R&D projects have addressed these bottlenecks and increased torque density. Key components have been redesigned: Our key innovations include optimizing the planetary stage layout, enhancing bearings and gears, and utilizing advanced materials with induction hardening. These technologies have been integrated into a single prototype to demonstrate system functionality and reliability. But which of these technologies will be integrated in your drivetrain depends on your needs: REVO is a variety of innovative features – tailored to your needs.
