Test rig for 30-MW wind turbines commissioned in Belgium

Capable of simulating loads a nacelle powertrain might experience in its lifetime, the test rig is designed to improve product reliability and shorten time to market.

The test rig at the company’s prototype centre in Lommel, Belgium is now ready for operation and will be used to validate powertrains and gearboxes for both onshore and offshore wind turbines.

ZF Wind Power head of product portfolio management Bert Verdyck said, “Testing allows us to contain the risks inherent to the wind industry and it is essential to receive approval from customers, insurers, and certification agencies.

“We started installing what is now the world’s largest test rig in 2023. Now it is up and running and ready for the development of next-generation powertrains.”

With a length of 50 m, the rig tests the dynamic behaviour of main bearings, gearbox and generator at system level, under real conditions with functional load tests and dynamics. It has a maximum torque of 45 MNm, maximum bending moment of 64 MNm, and a maximum axial force of 7,500 kN.
