Abstract: A wind turbine includes a generator with a stator and a rotor mounted for providing electrical power to an electric grid. The wind turbine includes a stator having a core with a plurality of individual adjacent segments coupled together for forming a segmented core. A concentrated winding element is wound around each stator core segment for generating flux in the core segment. An insulation element is positioned between adjacent core segments for electrically isolating adjacent core segments from each other, the stator core is coupled with a stator support element that is coupled to a generator housing, wherein the stator support element is an electrically insulative element or wherein the stator support element and each stator core segment are electrically isolated from each other.
