The invention describes an electrical coil arrangement (21) comprising at least one conductor turn (wi; wl, w2) with two conductor branches (23a, 23b), the first conductor branch (23a) of which is designed as a forward conductor with respect to the prespecified current flow direction and the second conductor branch (23b) of which is designed as a return conductor with respect to this current flow direction. In this case, the individual conductor branches (23a, 23b) are in the form of pressed litz wire conductors which are made stable by a cured filling material (40) and have a large number of electrically conductive individual wires (38), wherein each individual conductor branch (23a, 23b) is formed as a separate, prefabricated conductor segment (27) which is subsequently electrically conductively connected to one another, associated conductor branch (23b, 23a) in at least one end region (17). The invention further describes an electrical machine (1) comprising a coil arrangement (21) of this kind, and a method for producing a coil arrangement (21) of this kind.
The invention relates to a stator (3) for an electric alternating-current machine (1) with a number of magnetic poles p, wherein the stator (3) comprises a central axis A, said stator (3) comprises a stator winding (4) with a plurality of conductor windings (13j), a portion (l) of each winding running helically in relation to the central axis (A), and wherein the individual conductor windings (13j) are grouped together to collectively form n phase windings (u1, u2 to w3, w4), characterised in that the number n of the phase windings is higher than three, particularly an integral multiple of three. The invention further relates to an electric machine (1) comprising such a stator (3).
