Abstract
A stator for an electric machine has a plurality of pins, which are arranged on concentric circles at different distances from a stator center point in slots and each concentric circle forms a layer, wherein four pins in different layers are respectively 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, a fourth pin of the winding is located in the second slot in the 4n−1 layer.
