  ©Siemens AG 2012. All Rights Reserved. Generators for Wind Turbines  ©Siemens AG 2012. All Rights Reserved. Industry Sector –HUSUM 2012September 2012  Application The generator is the core of a wind turbine. It converts the rotational energy of the rotor, driven by the kinetic energy of the wind, and converts it into electrical energy using induction.Therefore, it generates the electric power that the wind turbine system feeds into the grid.  ©Siemens AG 2012. All Rights Reserved.
