Higher Power Density Through Lightweight Design and Planetary Stages

The increase in power density was enabled by significant weight reduction and the use of multiple planets in three planetary stages for balanced ratio distribution. High Densityx covered the full portfolio from low-wind turbines to large offshore machines and helped optimize space and weight requirements in earlier turbine generations.


Key benefits of the High Densityx concept included:

  • Multiple planets in planetary stages for balanced ratio distribution
  • Increased gear load capacity
  • Topology optimized structures
  • More than 25 percent increase in torque density
