Successful certification of Winergy HybridDrive components
The HybridDrive from Winergy successfully completed all the prototype tests at the
system level in September 2012. Now, TÜV Rheinland verifies the properties of
HybridDrive after successful certification of the components in compliance with GL
2010. With this as basis, this innovative drive system has the best prospects for the
On April 9, 2013, at the Winergy booth at the Hanover Fair, Frank Witte, Deputy Head of the
Certification Office for Wind Energy Systems with TÜV Rheinland, handed over the certificate
to Matthias Deicke, Winergy project manager for HybridDrive. This certificate confirms that
HybridDrive successfully completed the design verification in compliance with the
requirements of the GL2010 directive.
""We are very satisfied that the HybridDrive system, comprising gearbox and generator, was
able to be so quickly certified. As a consequence, we can offer our customers a real benefit
as HybridDrive has been checked and verified regarding basic production criteria and
specification features by TÜV Rheinland – as independent and approved Institute – even
before a turbine is engineered. This saves our customers a substantial amount of money in
the complete type certification process"", explained Matthias Deicke after he received the
The certified HybridDrive was developed by Winergy for a new wind turbine system
belonging to W2E Wind to Energy, based in Rostock, Germany.
The close cooperation between Winergy and W2E Wind to Energy when developing the new
W2E-120/3fc wind turbine system shortened the development time, both for the wind turbine
system as well as for the HybridDrive. Further, the results of the HybridDrive achieved in the
system test were convincing. A rated efficiency of over 96% was able to be successfully
verified – an extremely good value. This value applies to the combination of gearbox and generator, whose designs have been optimally harmonized and coordinated with one
Both individual components achieve an efficiency of approx. 98%. The certified HybridDrive
has a rated torque of approx. 2550 kNm, a power of 3 MW and weights approximately 34 t
(including the oil lubrication system). HybridDrive has been designed for wind turbine
systems with a rotor diameter of 120 m. Other sizes and power ratings are available on
After some delay in the project, this future-proof technology will continue to move forward as
W2E Wind to Energy was able to successfully sell licenses for this turbine to other
companies. It is assumed that the first 3 MW wind turbine systems under license from W2E
will be equipped with a HybridDrive from Winergy in the coming months.
Winergy, with its headquarters in Voerde, Germany, is the leading drive train component
manufacturer for wind turbines. It has supplied more than 70,000 gearboxes. With more than
30 years of experience, Winergy offers gearboxes, couplings and services to wind turbine
manufacturers as well as wind park owners / operations & maintenance companies. The
product portfolio covers power ratings between 750 kW and 6.5 MW. This is complemented
by a high quality professional service portfolio. Production and service locations are located
in Europe, China, India and the US, while the base of service partners is expanded
continuously on a global level.
About W2E Wind To Energy GmbH
W2E Wind to Energy GmbH develops complete wind turbine systems in the multi-megawatt
class. It also certifies and supports the operation of prototypes. W2E independently initiates,
supports and gets involved in all of the relevant areas of the development phases. The
services it performs in-house include developing the concept, designing the machine
elements, dynamic simulations, load calculations, FEM, operational control and closed-loop
control and designing and specifying the electrical systems.
The results of the development are offered to potential customers in the form of a license.
The product comprises the documentation, which allows the licensee to manufacture, erect, commission and maintain the developed wind turbine systems. The documentation includes
calculations, verifications, certificates, parts lists, specifications, descriptions, drawings etc.
including training documentation.
W2E Wind to Energy GmbH was founded back in May 2003. The number of employees has
risen from 7 up to 30. A subsidiary has been established in Canada. W2E has business
relationships with customers in Germany, China, India, Turkey, Iran and other countries. The
portfolio includes wind turbine systems with ratings of 1.3 MW, 2.0 MW, 2.5 MW and 3.0 MW.
