Definitions
- the invention relates to a method for producing a coil winding and a winding template that is suitable for use in the method.
- One way to produce coil windings is to produce a flat wave winding by helically winding a conductor wire around an elongated, flat winding template. This wave winding is then inserted into slots in a stator or rotor body, where it forms a coil winding that runs around the circumference of the stator or rotor body at least once.
- a winding device for generating wave windings by helically winding conductor wire is used.
- a conductor wire or an entire bundle of conductor wires is offset several times in the area of the transition from one side of the winding template to the other side of the winding template, so that end windings are created and the respective wires open form wire webs on the sides of the winding template.
- the wave winding produced in this way is either drawn directly into the slots of rotors or stators, or transferred to a transfer tool that corresponds geometrically to the stator or rotor body.
- the retracted wave winding forms the coil winding of the stator or rotor.
- Such a method is known, for example, from DE 102015 120661 A1.
- a flat winding mat having an arbitrary length can be obtained.
- individual wire webs of conductor wires which are each arranged between two winding heads, can also form more than one layer and change their position relative to one another over the course of the wave winding.
- Such a wave winding can be used as a coil winding in the stator or rotor body, as described above.
- the winding can also be drawn in in multiple layers and, due to the continuity of the winding, requires little electrical connections to be made subsequently for individual partial windings or groups of conductors.
- the disadvantage of such a multi-layer insertion of a wave winding is that the radius of the coil winding changes with each wave winding layer of the wave winding inserted into the stator or rotor slots. As a result, the end windings of the wave winding require more space when viewed axially as the pull-in radius decreases.
- the wave winding consequently forms a frustoconical geometry at the axial ends of the rotor or stator.
- Such a geometry is disadvantageous with regard to the power density of electric motors, since due to these truncated cone-like areas of the winding, an axial space available for the stator or rotor in the electric motor cannot be used.
- the object of the invention is therefore to overcome the disadvantages of the prior art and to produce a method for producing a coil winding and a Wi ckel template, whereby the available space by geo metrically optimized coil or shaft windings for stators or rotors effi cient can be used.
- the invention relates to a method for producing a wave winding for forming a coil winding with at least one wave winding layer in a stator or rotor body, with a winding template being rotatable about a longitudinal axis and being provided with at least one winding section with a winding width, comprising the method steps:
- the winding template is formed with at least one further winding section with a different winding width and previous steps are repeated at least in the further winding section with a different winding width.
- the winding starts at one end of the winding template with a large winding width or at one end of the winding template with a small winding width of a winding section. It is also conceivable that if there are more than two winding sections on the winding template, one starts with an inner winding section.
- the advantage of the method according to the invention is that the winding width of the wave winding can be designed in such a way that the changing radius for the coil winding with each wave winding position is compensated.
- this is advantageous with regard to the achievable geometries, since truncated cone-like geometries of the coil windings in the area of the end windings can be avoided and cylindrical geometries can be achieved.
- Electric motors with such geometries have a higher power density in relation to the available axial length.
- higher performance is achieved or the stator or rotor is to be designed smaller—in contrast to designs with frustoconical end windings.
- an axial displacement of the winding template along its longitudinal axis is provided for transferring the coil wires to be wound into the further winding section.
- This axial displacement can take place when the wave winding wound in the active winding section has reached a length which corresponds to the circumference of a wave winding layer of the coil winding used in the stator or rotor.
- the wave winding can be produced on the same winding template without removing or depositing areas that have already been wound and without converting the winding template to a different winding width, and it can be produced efficiently in one pass.
- an intermediate step is provided with an intermediate winding in an intermediate section when transferring from one winding section to the next winding section, with a winding width of the intermediate section between the winding widths of the winding sections located.
- the transfer from one winding section to the next winding section takes place when the wave winding has reached a length of one wave winding layer of the coil winding.
- an intermediate step in which an intermediate winding is created can be advantageous, since in a transition from a wave winding to a stator or rotor, the transition from a wave winding layer with a first circumference to a layer with a different circumference in the transition area is different Wire lengths or a different winding geometry may require.
- the intermediate winding can take place in an intermediate section of the winding template.
- the winding in the intermediate section can be done with a winding width different from the winding width of the previously used and subsequently used winding section.
- the procedural steps are repeated until a desired number of wave winding layers has been reached for insertion into the stator or rotor body.
- the coil winding produced in this way is made up of continuous conductor wires.
- a wave winding layer, in relation to the coil winding, is a length of wave winding which, in an installed condition, forms a circumferential layer of conductor wires in the stator or rotor body.
- the coil winding can thus advantageously be produced in one pass using the method and can be used in one piece either directly in a stator or rotor body or can be transferred into the stator or rotor body using a transfer tool.
- a method step can be provided, after which the wave winding is fed into a transfer tool for drawing the wave winding into grooves of a stator body or rotor body. The wave winding can be inserted into the transfer tool as a whole and then transferred as a whole into the stator or rotor slots.
- the wave winding being fed continuously to the transfer tool and being transferred continuously by the transfer tool into the stator or rotor grooves of the stator or rotor body.
- the shaft winding can be drawn directly into the stator or rotor when it is drawn into a rotor or stator with grooves that are open radially outwards.
- a coil winding can thus be produced for a circumference that increases or decreases with each wave winding layer, which has a constant axial expansion when installed in the stator or rotor body.
- a complex assembly of individual partial windings with different winding widths can be omitted. In this way, on the one hand, the reliability of the coil winding is increased, while the space requirement is optimized.
- a coil winding produced according to such a method can be produced in a shorter time due to the continuity of the conductor wires and can also be used in a stator or rotor body in a shorter time.
- the wave winding is completely stripped off the winding template and the wave winding is transferred to a transport device.
- the process can be further optimized in terms of space requirements, since the wave winding produced does not have to be drawn in on site or transferred to a transfer tool, but can be fed to another machine in a transport device or in the transport device between can be stored.
- the invention also relates to a winding template for producing a wave winding from parallel coil wires suitable for insertion into slots in a stator or rotor body, the winding template being rotatable and having a substantially rectangular cross section.
- the winding template can preferably be rotated in 180-degree increments.
- an embodiment of the winding template is advantageous in which the winding template has a sword-like shape, i.e.
- the winding width of the winding sections can be predetermined in such a way that the change in the winding width compensates for the difference in circumference for each wave winding layer of the drawn-in coil winding.
- the winding width is constant along the longitudinal axis within the respective winding sections. This prevents an axial extension with respect to the stator body or rotor body from changing within a wave winding layer of a coil winding used in a stator or rotor. In this way, a winding overhang that remains the same in the axial extent relative to the stator or rotor body is generated for each wave winding layer in the stator or rotor.
- the winding width of the winding sections increases in stages along the longitudinal axis. In this way, areas of a wave winding that have an increasing winding width can be generated sequentially in a particularly time-saving manner, since the winding template can be wound continuously.
- the winding can be started at one end with a large winding width or at one end with a small winding width of the winding section. It is also conceivable that, if there are more than two winding sections on the winding template, starting with an inner winding section.
- the winding width of the winding sections increases alternately from a free end of the winding template along the longitudinal axis.
- a coil winding can be produced which, when drawn into a stator or rotor body, has a homogeneous distribution of the winding overhangs, taking into account the circumferential variation with each wave winding layer.
- the winding areas have different lengths along the longitudinal axis of the winding template.
- the length of the respective winding sections can preferably be Be provided depending on the generated wave winding layers. In this way, the space requirement of the winding template is optimized along the longitudinal axis. Provision can also be made for an intermediate section to be arranged between two winding sections, which intermediate section can have a winding width that is different from the winding sections.
- the intermediate sections allow intermediate windings to be produced, which allow a transition from one wave winding layer of the coil winding to another wave winding layer lying radially further inwards or outwards in the stator or rotor body
- FIG. 1a shows a schematic view of a coil winding drawn into a stator or rotor body, which has been produced according to the prior art or has been produced using a winding template according to the prior art;

- FIG. 1a shows a schematic view of a coil winding 20 drawn into a stator or rotor body 100, which has been produced according to the prior art or has been produced using a winding template according to the prior art.
- the end windings 21a, b have a greater axial extent with each wave winding layer 23a, b lying radially further inwards.
- the coil winding 20 used piles up in such a way that the end windings in the stator or rotor body 100 form a truncated cone-like structure. This results in an increased space requirement, the axial distance between the radially outer wave winding layer 23a in this exemplary embodiment of the prior art and the radially inner wave winding layer 23b being unused.
- FIG. 1b shows a schematic view of a coil winding 30 drawn into a stator or rotor body, which has been produced from a wave winding by the method according to the invention or has been produced using a winding template 10 according to the invention.
- the winding overhangs 31a,b in contrast to FIG. 1a, which describes the prior art, all lie in one plane when viewed axially. Consequently, the wave winding layers 33a, b of the coil winding 30 are also completely overlapping. As a result, the space available for the coil winding 30 of the stator or rotor is optimally used.
- FIG. 2 shows a schematic representation of a winding template 10 according to the invention in a plan view of the first side 15 of the winding template 10.
- the winding template 10 is elongate and has a flat cross section.
- the winding template 10 thus has a sword-like shape, with the winding template 10 having a large length-to-width ratio in relation to its overall length and overall width.
- the thickness of the winding template 10 is selected as low as possible.
- the winding template 10 can be rotated about a longitudinal axis 11 by at least 180° in both directions.
- the winding template 10 can be displaced axially along the longitudinal axis 11 .
- the winding template 10 has a plurality of winding sections 13a, b, c, each of which has a constant winding width 12a, b, c.

- a winding template 10 in which, viewed from left to right, a winding width 12a, b,c that decreases in each case for the winding sections 13a, b,c is provided.
- the left-hand end of the winding template 10 can represent an open end, while a right-hand end with a stop, a swivel joint can have a closed end.
- intermediate sections 14a,b are provided, which can be wound when the length of the coil winding 30 produced has reached the circumference of a specific wave winding layer 33a,b of the coil winding 30 to be drawn into a stator body or rotor body 100.
- the coil winding 30 can take place in the respective intermediate section 14a, b.
- the increase in the winding width 12a, b,c of the winding sections 13a, b,c takes place in stages along the longitudinal axis.
- the winding can be started in the winding section 13a with a small winding width 12a at the open end of the former 10 .
- winding template 10 it is also possible to start at the closed end of the winding template 10 in a winding section 13c with a large winding width 12c. It is also conceivable that, if there are more than two winding sections 13a, b, c on the winding template 10, the winding starts at an inner winding section 13b.
- the increase in the winding width 12a, b, c of the winding sections 13a, b, c takes place from a free end of the winding template 10 alternately at a changing distance.
- the winding sections 13a, b, c can have different lengths along the longitudinal axis 11 of the winding template 10 .
- An intermediate section 14a, b is arranged between two winding sections 13a, b or 13b, c, which can have a different winding width to the winding sections 13a, b or 13b, c.
- Intermediate windings can be produced by the intermediate sections 14a, b, which enable a transition from one wave winding layer 33a of the coil winding 30 to another wave winding layer 33b lying radially further inside or outside in the stator or rotor body.
