1. A stator for an electric machine, comprising:
a plurality of pins arranged on concentric circles at different distances from a stator center point in slots wherein 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 a 4n−1 layer, wherein n is a natural number,
a second pin of the winding is located in a second slot in a 4n 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 a 4n−2 layer, and
a fourth pin of the winding is located in the second slot in a 4n−3 layer.
