Abstract
A stator for an electric machine includes a plurality of pins arranged on concentric circles at different distances to a stator center in slots, each concentric circle forming a layer, wherein six pins in different layers are serially connected to one another and form a winding. A first pin is located in a first slot in the 6n-1 layer, wherein n is an integer. A second pin is located in a second slot in the 6n 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 is located in a third slot in the 6n-2 layer. A fourth pin is located in a fourth slot in the 6n-3 layer. A fifth pin is located in the first slot in the 6n-5 layer. A sixth pin is located in the second slot in the 6n-4 layer.
