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, and each concentric circle forms a layer. In each case, four 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 4n−1 layer, wherein n is an integer. A second pin of the winding is located in a second slot in the 4n layer, wherein the second slot has a first radial distance to the first slot in a first circumferential direction of the stator. A third pin of the winding is located in a third slot in the 4n−2 layer, wherein the third slot lies adjacent to the first slot. A fourth pin of the winding is located in a fourth slot in the 4n−3 layer.
