23. Page 23 IntegralBlades ® - Motivation  Wind turbine blades are normally made by assembling blade shells and spars with glue joints  Glue joints represent weak spots as they are subject to cracking and may serve as entrance pathways for lightning strikes  Traditional blade production involves a potential risk of workers’ exposure to volatile organic compounds and other hazardous substances

24. Page 24 IntegralBlades ® - Innovation  The Siemens Integral Blade manufacturing process eliminates glue joints, delivering an integrated blade  The Integral Blade process delivers a blade with unrivaled strength and performance  The Integral Blade process uses unique glass consolidation and injection methods.  The Integral Blade process is protected by patents on key markets

29. Page 29  A wind turbine is typically fitted with a speed-increasing gearbox  The gearbox is a sensitive and expensive component  A 3.6 MW gearbox has 13 gear wheels, 22 bearings  Elimination of the gearbox will reduce the number of moving parts and could lead to further improvement in reliability Direct Drive - Motivation

30. Page 30 The DD technology project has had four phases: 1.Selection of preferred generator technology  1999-2005 2.Design and manufacturing of prototype generators  2005-2008 3.Testing under laboratory conditions  2008 4.Field testing in wind turbines  WTG1 July 2008  WTG2 March 2009 Direct Drive – Development since 1999
