Wind Technologies, leading the WinDrive Consortium, including SENVION, Romax, Mita-Teknik, Speedgoat, the University of Cambridge, and Delft University of Technology, are working on the industrialization of a revolutionary drivetrain concept, enabling the total lifetime capital costs of the drivetrain to be reduced by up to 83%!
A 3MW Brushless Doubly-Fed Induction Generator (DFIG) prototype is being constructed as a proof of concept. The project is expected to be completed by April 2015, and is sponsored by the EU’s Seventh Framework Programme with €1.5 million.
Brushless DFIG offers significant cost reductions and reliability improvements when compared with conventional DFIG’s. It does not require slip-rings or carbon extraction equipment, and as the machine operates at a slower speed than conventional DFIG, the failure-prone high-speed stage of the gearbox can be eliminated.
