Winergy participates in first virtual CWD Conference 2021

March 2021

Winergy once more participated in the Conference for Wind Power Drives CWD 2021. The event, usually held in Aachen Germany, was due to the COVID situation shifted to an online event available for every interested worldwide. “450 participants from 19 different countries and more than 120 presentations made the conference a great success.” was reported by the hosts.

Winergy participated with the following presentations:

“Comparing the dynamic behaviour of multi planet gearboxes with common planetary gearboxes” is the topic of Thomas Lubetz. He addresses the challenges of growing wind turbines, such as the increasing requirements for low noise emissions from wind turbines and how the multi-planet approach aims to minimize vibration through reduced excitation.

Roland Zeichfüßl presents the Integrated 3-Stage Planetary Gearbox with an Oil-Cooled Generator. The unique combination of technical advancements makes the HybridDrive a pioneer in this application.

Drivetrain development has to meet the challenges of design space and weight limits on the one hand and a remarkable increase of loads on the other hand. At the 5th CWD 2021 Dominik Daners, Winergy and Viktor Nickel, Nordex Group present how to overcome these boundaries successfully.

Sebastian Reisch discusses the elastic interaction of gearboxes in medium-speed powertrains. Increasing the integration level requires a gearbox design taking into account the stiffness dependent effects at the interfaces to surrounding components. The lecture compares different gearbox suspension concepts using the example of the Winergy HybridDrive and explaines how their elastic system behavior can be analyzed in simulation and measurement.

Many thanks to all visitors and the Center for Wind Energy Drives for making the event so lively even though the conference was held online. For everybody who could not join, feel free to contact us at to learn more about the lectures.
