Abstract
A stator for an electric machine includes a plurality of pins, which are 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 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−3 layer, wherein n is an integer, a second pin of the winding is located in a second slot in the 4n−2 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 the first slot in the 4n layer, and a fourth pin of the winding is located in the second slot in the 4n−1 layer.
