Abstract:
The invention relates to a stator (1) for an electric machine, comprising an essentially hollow-cylindrical laminated core (2) with multiple receiving grooves (4) which are arranged distributed. Multiple electric conductor sections (La, Lb) per receiving groove (4) formed by forming rods form a stator winding (14) with at least two part-windings (TWa, TWb). The at least two electric part-windings (TWa, TWb) are respectively formed by at least one first and one second electrically series-connected winding segment (WSa, WSb), wherein conductor sections (La, Lb) of the first winding segment (WSa) are electrically interconnected by means of first and second electric connecting sections (VBa, VBb) such that a helical current path (17a) is defined along a first radial direction (18a) to the longitudinal axis (3) of the laminated core (2) and conductor sections (La, Lb) of the second winding segment (WSb) are electrically interconnected by means of first and second electric connecting sections (VB a, VBb) such that a second helical current path (17b) is defined along an opposite, second radial direction (18b) to the longitudinal axis (3) of the laminated core (2).
