1. A stator for an electric machine, comprising:
a plurality of pins arranged in slots in the stator on concentric circles at different distances from a stator center point, wherein each concentric circle forms a layer,
wherein each layer is defined by n, wherein n is a natural number;
wherein:
each of six pins of the plurality of 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 a 6n-4 layer,
a second pin of the winding is located in a second slot in a 6n-5 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 6n-2 layer,
a fourth pin of the winding is located in the second slot in a 6n-3 layer,
a fifth pin is located in the first slot in a 6n layer, and
a sixth pin of the winding is located in the second slot in a 6n-1 layer.
