[0036] exist Figure 10 The winding device is shown in . According to this winding device 90, six struts 93 are arranged approximately in a hexagon. The six struts 93 rest on a support 96 which is mounted rotatably about an axis 99 in the longitudinal direction of the struts. In order to manufacture the winding semi-finished product 50, the wire or wires 106, 107, 108 are first fixed to the post 93 (initial winding post) at the beginning, and the winding device 90 is first rotated counterclockwise three laps. In this case, the wires 106 , 107 , 108 are wound in each case in such a way that the corresponding turns resulting from three turns of the winding device 90 are arranged in descending order on the strut 93 . After reaching the so-called turning point 110 , a turning connection 113 is placed along a strut 93 , here called “turning point strut”, which here connects the two halves of the wire 106 to each other. At a further deflection point 116 , the deflection connecti...

The invention relates to a method for producing a multiphase winding (83) for a stator of an electrical machine by means of a winding device (90), wherein a winding semi-finished product (50) is produced for this purpose and when producing the winding semi-finished product (50) A plurality of branches of the winding (83) are produced, and hereby two electrically series-connected half windings (119, 120, 121, 122, 123, 124) are produced from each branch of the winding, wherein each half The windings (119, 120, 121, 122, 123, 124) are made into a wave form with a wave side (133) in the shape of a star winding by means of a winding subgroup, characterized in that the half winding of the branch ( 119, 120, 121, 122, 123, 124) are arranged in a stacked manner so that the first half winding (124) of the first branch is followed by the first half winding (124) of the other branch along the stacking direction ( 122), and the first half winding (120) of another branch is immediately followed by the first half winding of the other branch, and the first half winding (120, 122, 124) forms the first a sub-stack, wherein a second sub-stack is formed on the first sub-stack along the same stacking direction, and the second half-winding (123) of the first branch is wound there, and the The second half winding (121) of the other branch is wound around the second half winding (121), and the second half winding (119) of the further branch is wound immediately after the half winding (121).
Description
technical field [0001] The invention relates to a method for producing a winding for a stator of an electric machine, in particular a three-phase generator of a motor vehicle. Background technique [0002] A method for producing a winding in a stator is known from documents DE 10 2008 018 971 A1 and JP 56094948, the winding being moved into the stator by means of an insertion method. [0003] The proven production technology is especially suitable for mass production due to short cycle times in the initial or intermediate stages of winding production. In this case, the phases of the winding are wound one by one and inserted one after the other. A pressing step is carried out between the respective insertion operations, in which the coil heads of the introduced phase are pressed radially outwards in order to provide space for the following phase. Therefore, the windings introduced require relatively long coil heads (Wickelkopf). In addition, the layered arrangement of seve...
