Abstract
A stator for an electric machine includes a plurality of pins arranged on concentric circles at different distances to a stator center in slots in the stator, and each concentric circle forms a layer. In each case, six pins in different layers are serially connected to one another and form a winding. A first pin of the winding is located in a first slot in the 6n-1 layer, wherein n is an integer. A second pin of the winding is located in a second slot in the 6n layer. A third pin of the winding is located in the first slot in the 6n-2 layer. A fourth pin of the winding is located in the second slot in the 6n-3 layer. A fifth pin is located in the first slot in the 6n-5 layer. A sixth pin of the winding is located in the second slot in the 6n-4 layer.
