This follows successful prototype testing of the HybridDrive on system level at Winergy in September 2012 and certification of the components.

The HybridDrive has been installed in W2E’s Wind-to-Energy wind turbine in Kankel near Rostock, Germany. The 120/3fc turbine has a hub height of 100 m and a rotor diameter of 120 m.

Winergy’s HybridDrive combines a two-stage-planetary gearbox and a permanent magnet generator into an integrated drive train. This results in a length reduction of 35–50% for the complete drive train. Both the gearbox and generator have an efficiency each of 98%, leading to system efficiency of more than 96.5%. The current 3 MW version of the HybridDrive has a nominal torque of 2,550 kNm with a weight of 34t, including oil supply system. The HybridDrive is considerably lighter in comparison to other drive train concepts in the 3 MW class.
