Abstract (en)

[origin: CA2992655A1] The invention relates to an annular stator for an electric generator for a wind turbine, comprising a plurality of grooves (17) for accommodating the stator winding, and a magnetic yoke. Several sets (15) of cooling channels (19) which can subjected to cool air are provided in the region of the stator yoke. The stator consists of a plurality of stator sheets stacked in the axial direction and the cooling channels extend through all the stator sheets in the axial direction.
