The invention relates to a method for producing a wave winding for forming a coil winding (30) with at least one wave winding layer (33a, b) in a stator or rotor element (100), wherein a winding former (10) is provided with at least two winding sections (13a, b, c) and such that it can be rotated about a longitudinal axis (11), comprising the following method steps: Applying parallel coil wires to a first side (15) of the winding former (10) in a winding section (13) of the winding former (10); forming winding heads (31a, b) by alternately axially shifting the parallel coil wires on the winding former (10) and winding same about the rotated winding former (10); repeating steps a and b until the wave winding has reached a length of a first wave winding layer (33a) of the coil winding (30), wherein, according to the invention, the steps a to c are repeated in another winding section (13b) with a different winding width (12b). The invention also relates to a winding former (10) for producing a wave winding of this type which is suitable for introduction into grooves of a stator or rotor element (100).
A method for producing a wave winding for forming a coil winding (30) having at least one wave winding layer (33a,b) in a stator or rotor element (100), with a winding former (10) that can be rotated about a longitudinal axis (11) and has at least one winding section (13a) with a winding width (12a), having the method steps:
The method according to any one of the preceding claims, characterized in that an intermediate step having an intermediate winding in an intermediate section (14a,b) is provided in the transfer from one winding section (13a) to the next winding section (13b,c), wherein a winding width of the intermediate section (14a,b) lies between the winding widths (12a,b,c) of the winding sections (13a,b,c).
The method according to any one of the preceding claims, additionally having the method step:
The method according to any one of the preceding claims, wherein steps a to c are repeated in winding sections with increasing winding widths.
The method according to any one of the preceding claims, additionally having the method step:
The method according to any one of the preceding claims, additionally having the method step:
