Coil winding for insertion into radially open slots of stators or rotors of electrical machines, wherein the coil winding consists of a number of wires which are braided with one another and are bent several times in opposite directions such that limbs (28, 30), which lie parallel in relation to one another, of the wires, which are intended to fill the slots, are connected by winding overhangs (32, 34) which project beyond the end sides of the stators or rotors, wherein the winding overhangs (32, 34) each have two obliquely running winding overhang sections (36, 38, 40, 42) with a winding overhang tip (44, 46) lying in between, wherein the wires are arranged one behind the other in a longitudinal direction of the coil winding, wherein the wires are split into a first and a second group, wherein the wires of a group are associated with the different phases of the electric motor and there is an even number of wires for each phase, wherein the same number of wires per phase is associated with each group, and the wires of one group are arranged immediately adjacent at least in the region of the limbs (28, 30) and one behind the other in the longitudinal direction of the coil winding, wherein in each case an upwardly directed limb of a wire of the first group overlaps a downwardly directed limb of a wire of the second group, the groups each have at least two wire groups, the wire groups each have three wires, wherein a corresponding wire group of the second group is in each case associated with each wire group of the first group, wherein in each case an upwardly directed limb of a wire of a wire group of the first group overlaps a downwardly directed limb of a wire of the corresponding wire group of the second group, that the wires of a wire group have the same phase (A, B, C) and, in a manner distributed over the entire length of the coil winding in the longitudinal direction, winding overhangs (32, 34) of at least one wire protrude transversely in relation to the longitudinal direction beyond the winding overhang (28, 30) of the two further wires of the wire group D which follow in the longitudinal direction such that the first wire, in a region of the limbs (28, 30) which follows the winding overhang (32, 34), lies in front of the two wires which first follow in front of the winding overhang (32, 34), wherein the order of the wires is only changed within the respective wire group, i.e. within one phase (A, B, C), such that the interference of the wires of different phases (A, B, C) with one another is minimised. the wires are split into a first and a second group, wherein the wires of a group are associated with the different phases of the electric motor and there is an even number of wires for each phase, wherein the same number of wires per phase is associated with each group, and the wires of one group are arranged immediately adjacent at least in the region of the limbs (28, 30) and one behind the other in the longitudinal direction of the coil winding, wherein in each case an upwardly directed limb of a wire of the first group overlaps a downwardly directed limb of a wire of the second group, the groups each have at least two wire groups, the wire groups each have three wires, wherein a corresponding wire group of the second group is in each case associated with each wire group of the first group, wherein in each case an upwardly directed limb of a wire of a wire group of the first group overlaps a downwardly directed limb of a wire of the corresponding wire group of the second group, that the wires of a wire group have the same phase (A, B, C) and, in a manner distributed over the entire length of the coil winding in the longitudinal direction, winding overhangs (32, 34) of at least one wire protrude transversely in relation to the longitudinal direction beyond the winding overhang (28, 30) of the two further wires of the wire group D which follow in the longitudinal direction such that the first wire, in a region of the limbs (28, 30) which follows the winding overhang (32, 34), lies in front of the two wires which first follow in front of the winding overhang (32, 34), wherein the order of the wires is only changed within the respective wire group, i.e. within one phase (A, B, C), such that the interference of the wires of different phases (A, B, C) with one another is minimised.
