1. A wind turbine including a generator with a stator and a rotor mounted for providing electrical power to an electric grid, the wind turbine comprising:
the stator having a stator core with a plurality of individual adjacent core segments coupled together for forming a segmented core;
a concentrated winding element wound around each stator core segment for generating flux in the core segment; and
an insulation element positioned between adjacent core segments for electrically isolating adjacent core segments from each other, wherein
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.
