Abstract
A stator for an electric machine having a plurality of pins, which are arranged on concentric circles at different distances from a stator center point in slots in the stator, and each concentric circle forms a layer, where four pins in different layers are connected to one another in series and form a winding. A first pin of the winding is located in a first slot in the 4n-3 layer, wherein n is a natural number, a second pin of the winding is located in a second slot in the 4n-2 layer, wherein the second slot is at a first radial distance from 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-3 layer.
