Abstract (en)
[origin: WO2022128695A1] Disclosed is a stator (1) for an electric machine (51), wherein - the stator (1) includes a distributed stator winding (2) with a number N of phase windings, a number P of pole pairs, and a stator core (3) in which slots (A) are formed, the stator winding (2) being arranged in the slots (A); - the stator core (3) is subdivided into 2∙P∙N winding zones (8a-f) regularly following each other in the circumferential direction and includes a plurality of axial recesses (4a-l); - the recesses (4a-l) form at least one set (5a-c) of recesses (4a-d, 4e-f, 4i-l) which follow each other in the circumferential direction, and at least two recesses (4a-d, 4e-f, 4i-l) of the set (5a-c) are part of one of the winding zones (8a-f); - each pair of recesses (4a-d, 4e-h, 4i-l) that adjoin each other in the circumferential direction and are part of the same winding zone (8a-f) has a first angular distance (11a-c, 15a-c, 20a-c) from each other in the circumferential direction; - each pair of recesses (4a, 4d, 4e, 4h, 4i, 4l) which adjoin each other in the circumferential direction and are part of different winding zones (8a-f) has a second angular distance (11d, 15d, 20d) from each other in the circumferential direction; and - in at least one set (5a-c), the first angular distance (11a-c, 15a-c, 20a-c) and the second angular distance (11d, 15d, 20d) differ from one another such that the set (5a-c) is an irregular set.
