The two motors will allow the test rig developed by Danish wind turbine test specialist R&D Test Systems to serve as a powertrain and gearbox test bench at 60 metres long.
This 30 MW test bench will be housed in ZF Wind Powers’ Test and Prototype Center in Lommel, Belgium. The test rig is expected to simulate the multiplicity of wind loads that a nacelle powertrain might experience in its lifetime, helping to improve product reliability and shorten time to market.
The test rig will be able to test two powertrains or two gearboxes simultaneously. The two motors are positioned on each end of these nacelle components under test, with an additional load unit located between them that simulates wind loads comparable to real-world conditions Together, the motors and load unit can stimulate not only harsh wind loads, but also the effect of wind coming from different directions.
Marek Lukaszczyk, Europe and Middle East marketing manager for WEG, said: “WEG has extensive experience in supplying motors for renewable projects, so we are confident that our motors will help to ensure that this test rig operates at peak performance.
"Rigorously testing new technologies for renewable energy generation is essential for our planet's future. The two motors from WEG will be delivered in October 2023, and the system will ultimately be delivered to ZF Wind Power in 2024.”
Ralf Nieschler, key account manager, R&D test systems said in the press release from R&D Test Systems: “The wind loads and directions can vary greatly, and each change creates loading on the nacelle powertrain. This new test rig must be much more powerful than the powertrain it tests, providing proof that the next generation of offshore turbines are capable of operating reliably in extreme offshore conditions over the defined lifetime.
“The force of gusts of wind can push the blade around. This twisting and bending of the powertrain in all possible directions in the test rig will simulate the effect of 20 years of wind conditions, in just a few months,” concluded Nieschler.
The test rig is scheduled to be delivered in 2024. WEG’s motors will be a key component of the test rig and will be instrumental in helping to ensure wind technology is up to future standards.
