Information material


  • The HybridDrive offers great power train cost-saving potential thanks to a high level of system knowledge based on longtime Winergy experience.
  • Multiple planets and three planetary stages promise torque density above 200 Nm/kg.
  • The first compact oil-cooled medium-speed generator of it's kind allows identical construction for all grid frequencies.
  • The functional integration of gearbox and generator results in a reduction of the drive train construction up to 50%.

The HybridDrive is Winergy's response to the challenge of further reducing the costs of energy generation. With the direct connection of a three-stage planetary gearbox and a permanent-magnet synchronous generator, a medium-speed drive has been designed ensuring the high efficiency. Both Winergy‘s mechanical and electrical engineering expertise are reflected in the HybridDrive.


  • High system efficiency
  • Compact and flexible for different concepts
  • Space-saving due to 50% shorter design
  • Durable and easy to maintain
  • Resource-saving design

The HybridDrive can be flexibly integrated into any nacelle configuration. Converters and transformers can be positioned modularly at the top of the nacelle or at the bottom of the tower. In addition, the system offers a high modularity: The permanent magnet generator allows identical construction in all grid frequencies without any ratio change. Due to the compact design, the drive train is very robust against weather conditions, e.g. sandstorms. Compared to the direct drive system, the proportion of rare earths is 80 % lower, which enables simplified and long-term cost calculation.
