Abstract
The invention relates to a method for producing a coil winding (70) for insertion into radially open slots (82) in a rotor or stator (80) of an electrical machine, wherein the coil winding (70) has a wire pack (60) consisting of a number of wires (32), wherein the wires (32) of the wire pack (60) run parallel to one another and are connected to one another in pairs at one end of the wire pack (60), and wherein the coil winding (70) is formed by a flat winding former which can be rotated about an axis of rotation (26). According to the method, the wire pack (60) is fixed on a winding former (26) and winding heads (42) are produced by displacing fixations of the wire pack (60). The winding shaft (26) can be rotated so that, after carrying out the method, a coil winding (70) is present in the form of a wave winding having wires (32) of the wire pack (60) preconnected in pairs at one end. Such a method allows a particularly space-saving coil winding (70) to be produced, which has a particularly high mechanical stability and requires the least amount of installation space in a rotor or stator (80).
