A stator (1) for an electric machine (101), wherein the stator (1) has N≥3 phases (U, V, W), P≥2 pole pairs, and q≥1 holes, the stator (1) comprises a stator core (3) having at least 2NPq slots (4) and a number of 2NPqL shaped conductors (5) arranged in an even number of L≥4 layers (6a-h) radially layered in the slots (4), the shaped conductors (5) form 2q paths (7a-d) per phase and are arranged in 2P winding zones (8), which each extend radially over L layers (6a-h) and in the circumferential direction over at least q directly adjacent slots (4), the shaped conductors (5) of each path are connected in a series circuit, which is provided by connectors (9a-e, 10a-f, 11a-g) arranged at both end faces (2a, 2b) of the stator core, each path comprises L/2 groups (12a-d) of shaped conductors (5) successively connected in series, each group (12a-d) is formed by at least one arrangement (13a, 13b) of at least four shaped conductors (5) which are arranged alternately in two immediately adjacent layers (6a-g) and are connected in series by first connectors (9a-e) which each provide an offset by qN slots (4) and an offset by one layer, and pairs of groups (12a-d) adjacent with respect to the series connection are each connected by a second connector (10a-f) which provides an offset by a plurality of slots (4) and an offset by two layers.
