Abstract (en)
[origin: WO2021048085A1] The invention relates to a stator (1) for an electric machine (401), comprising a plurality of pins (21, 22, 23, 24, 31, 32, 33, 34) which are arranged in grooves (51, 52, 53, 54, 55, 56, 57, 58) in concentric circles at different distances from a stator centre point (M), with each concentric circle forming a layer (L1, L2, L3, L4), wherein four respective pins (21, 22, 23, 24, 25, 31, 32, 33, 34, 35) are connected in series with one another in different layers (L1, L2, L3, L4) and form a winding (41): a first pin (21) of the winding (41) is positioned in a first groove (51) in the 4n-1 layer (L3), wherein n is a natural number; a second pin (22) of the winding (41) is positioned in a second groove (52) in the 4n layer (L4), wherein the second groove (52) is at a first radial distance (71) from the first groove (51) in a first circumferential direction of the stator (1); a third pin (23) of the winding (41) is positioned in the first groove (51) in the 4n-3 layer (L2); and a fourth pin (24) of the winding (41) is positioned in the second groove (52) in the 4n-3 layer (L1).
