Abstract (en)
[origin: WO2022179706A1] A stator (4) for a multiphase electric machine (2), comprising a core element (10) that comprises stator slots (12) for receiving at least two winding arrangements (14, 16, 18) which each comprise at least two conductor arrangements (20, 22; 24, 26; 28, 30) running in parallel and each form a phase in such a way that what is known as a distributed winding is present, wherein each conductor arrangement (20, 22; 24, 26; 28, 30) of a winding arrangement (14, 16, 18) comprises at least two successive jumps in the circumferential direction, wherein the respective jump width SLW of the respective conductor arrangement (20, 22; 24, 26; 28, 30) at each partial end winding (40, 42, 44) is newly defined with n=1 according to the formula SLW=(m-1)q + 1 + 2(n-1) beginning with the respectively inner conductor arrangement (20, 22; 24, 26; 28, 30), wherein m is the number of phases and wherein q is the number of conductor arrangements (20, 22; 24, 26; 28, 30) associated with a winding arrangement (14, 16, 18) and n is alternately 1 to q, as seen in the circumferential direction. The invention also relates to an electric motor (2) and to a method for producing a stator (4).
