Fraunhofer bearing test bench opens in Hamburg-Bergedorf

Tests of huge rotor blades now possible at IWES

Katharina Fegebank, Senator for Science, Research and Equal Opportunities, inaugurated Monday (May 6, 2019) a test bench for blade bearings along with a new institute site at the Fraunhofer Institute for Wind Energy Systems in Bergdorf. Tests of blade bearings measuring up to six metres in diameter will be tested there under realistic conditions in future.

New test bench for blade bearings

Tests into the durability of bearings for their entire operating life – before they are installed on a wind turbine – can be conducted in the new “Large Bearing Laboratory”. The new generation of wind turbines has rotor blades measuring up to 80 metres in diameter. The blade bearings connect the hub and rotor blades of the wind turbines and are exposed to enormous forces. The large test bench will help prevent damage, long downtimes as well as high costs.

Transforming the energy system

“The establishment of the Fraunhofer IWES will strengthen the energy campus as a leading centre of wind energy research in Hamburg. Together, we will work on new solutions for the energy transition in sector coupling,” said Prof. Werner Beba, Head of the Competence Center for Renewable Energies and Energy Efficiency (CC4E) at HAW Hamburg.

The Fraunhofer IWES operates the test stand and intends to use the infrastructure with CC4E for application-orientated research. The German Ministry of Economics and Energy has provided EUR 12 million in funds while the City of Hamburg has invested EUR 8.3 million.
