Zusammenfassung: | 1. A stator (1) for an electric machine (51), whereinthe stator (1) has a distributed stator winding (2) having a number N of phase windings, a number P of pole pairs and a stator core (3), in which slots (A) are formed, wherein the stator winding (2) is arranged in the slots (A); whereinthe stator core (3) is divided into 2×P×N winding zones (8a-f) which follow each other uniformly in a circumferential direction; whereinthe stator core (3) has a large number of recesses (4a-l) which extend in an axial direction from a first end face of the stator core (3) to a second end face, which is opposite the first end face, of the stator core (3); whereinthe recesses (4a-l) form at least one arrangement (5a-c) of recesses (4a-d, 4e-f, 4i-l) which follow each other in a circumferential direction and at least two recesses (4a-d, 4e-f, 4i-l) of the arrangement (5a-c) belong to one of the winding zones (8a-f); whereineach pair of recesses (4a-d, 4e-h, 4i-l) which are adjacent in a circumferential direction and which belong to the same winding zone (8a-f) has a first angular spacing (11a-c, 15a-c, 20a-c) in a circumferential direction relative to each other; whereineach pair of recesses (4a, 4d, 4e, 4h, 4i, 4l) which are adjacent in a circumferential direction and which belong to different winding zones (8a-f) has a second angular spacing (11d, 15d, 20d) in a circumferential direction relative to each other; characterized in thatin at least one arrangement (5a-c) the first angular spacing (11a-c, 15a-c, 20a-c) and the second angular spacing (11d, 15d, 20d) are different so that the arrangement (5a-c) is in the form of a non-uniform arrangement. |
