The new generator will be scaled for both direct-drive and medium-speed drive trains.
Traditional doubly-fed induction generators have the disadvantage of requiring extensive and costly routine servicing of their brush gear and slip-rings. Permanent magnet generators avoid this maintenance need.
Earlier this year a consortium led by the US National Renewable Energy Laboratory, which includes Danotek was one of six groups assigned by the Department of Energy to advance next-generation designs for wind-turbine drivetrains.
The aim is to develop drivetrains of 10MW or more.
