Abstract
In a stator for an electric machine and a method for manufacturing a winding for the stator of such an electric machine L-shaped wire segments having a rectangular cross-section are inserted into slots arranged around the stator The long leg of the L-shaped wire segment is then inserted, into or through, a respective slot and the wire segment is then bent into an S-shape resulting in a second short leg while reducing a length of the long leg. The first short leg of each one of a majority of the wire segments is then electrically connected to the first short leg of another one of the wire segments and the second short leg of each one of a majority of the wire segments is electrically connected to the second short leg of yet another one of the wire segments.
