YOU HAVE THE CHOICE WITH THE WINERGY FLEXIBLE FIT CONCEPT!

… because the best powertrain is the one where you can achieve the maximum benefit!

Listening to Markets‘ VoicesAt Winergy, we listen to the markets’ voices. The trend towards midspeed generator concepts as well as the increasing rated power of wind turbines will double the nominal torque in relation to 50% market volume by 2030.
Our Goal for the FutureBecause of increasing turbine power, we need scalable drive train concepts with one-off development and validation for different outputs. The goal for the future is to reduce costs but maintain the high Winergy quality despite shorter development times.
Different Drivetrain ConceptsWe see that large and modern turbines over 6 MW increasingly use preloaded tapered roller bearings as mean bearing units’ arrangements. The drivetrain concept change from 3-PRS to 2-PRS or 4-PRS with mean bearing units.
PRS: x-point rotor support
Your Choice…With the Winergy FlexibleFit we will rise this concept to the future of wind drive train technology. The combination of modularization, standardization and flexible interfaces save development time and costs while maintaining the high Winergy quality. You have the choice to find the concept that best fits your needs and the environment of your wind turbine!

Standardized product

The Winergy HybridDrive is predeveloped for different torque ranges with optimized ratio. This geared generator is the base product for FlexibleFit Solutions with a design independent from tilt and yaw wind loads. It brings easy and simple generator interfaces and no need of gearbox-generator specification. With our HybridDrive we are using the gearbox bearing also as generator bearing. These interactions through integrated concepts involving components require detail and system competence which we live at Winergy.
The HybridDrive offers the lowest weight possible due to system optimization with lowest possible generator weight and a bearing design made to match gearbox and generator requirements. The standardized geared generator is designed according Winergy guideline and has proven quality, reliability and is validated.

Modular concept FlexibleFit

Starting from a minimal cost approach based on a geared generator without planet carrier bearings in the low speed stage and minimum of support structure within the pure torque loaded base product. This standardized geared generator can be adapted to the customer needs and fits best to your preferred powertrain configuration. With a FlexibleFit module the HybridDrive can be easily adapted to existing and new drive train configurations. Easy connection to turbine support structures on the rotor side and an easy electrical interface on generator side are customer benefits. Regional differences and turbine platforms can be served with the combination of FlexibleFit with a standardized geared generator.
The modular drivetrain adaptation concept offers fast realization of prototypes and scalable power range. One responsibility and one location for powertrain assembly and testing enables a ready to install powertrain on site with preparation for future digitization.
