Description

[0001] The present invention relates to a method for manufacturing an element of a power generation component for an electric rotating shaft, and a power generation component for an electric rotating shaft having at least one element manufactured according to the method for manufacturing an element of a power generation component for an electric rotating shaft.

[0002] An electric rotating shaft, as a power generation component, comprises a rotor and a stator. It can be configured as a radial flux machine or an axial flux machine.

[0003] These machines typically have teeth on the stator, with the winding of at least one conductor element guided in slots between the teeth.

[0004] To improve the efficiency of electrically rotating shafts, the teeth are typically made of laminations. These laminations consist of a large number of very thin laminations arranged in their respective stacks. In order to support the torque transmitted from the stator to the associated rotor, the laminations must be fixed in place.

[0005] WO 2021 003 510 A2 discloses a stator for an axial flux machine, comprising a plurality of stator teeth having tooth bodies and loop elements, and having multiple sets of coil windings, wherein the loop element is composed of a wound lamination stack having recesses in which the tooth bodies of the stator teeth are arranged or formed therefrom are arranged. The laminations of the lamination stack can be connected to each other by welding.

[0006] EP 3 174 183 A1 discloses an electric motor, particularly an axial flux motor, having a rotor rotatably supported around a machine shaft, and a stator. The stator has a sintered support structure and inserts connected thereto, the inserts at least partially forming pole shoes and including a lamination stack. The laminations of the lamination stack can be connected to each other by welding.

[0007] Based on this, the object of the present invention is to provide a method for manufacturing a power generation component for an electric rotating shaft, and a correspondingly manufactured power generation component for an electric rotating shaft, by means of which the fixing of individual laminations for forming tooth laminations is achieved in a simple, cost-effective and time-saving manner.

[0008] This task is accomplished by a method for manufacturing an element of a power generation component for an electric rotating shaft according to claim 1, and by a power generation component according to claim 9. Advantageous embodiments of the method for manufacturing an element of a power generation component for an electric rotating shaft are given in dependent claims 2 to 8. An advantageous embodiment of the power generation component is given in dependent claim 10.

[0009] The features of each claim can be combined in any technically meaningful manner, and reference can also be made to the description below and the features in the drawings, which include supplementary embodiments of the invention.

[0010] This invention relates to a method for manufacturing an element of a power generation component for an electric rotating shaft, wherein a plurality of laminations are provided in a stacked manner in a lamination stack that at least partially forms a tooth, a support lamination is provided, and the support lamination is disposed on one side of the lamination stack. The support lamination is defined to be connected to the plurality of laminations of the lamination stack by welding along at least one weld seam. This element of the power generation component can be a support element that is fixed to another element of the stator after welding, for example, fixed to a stator carrier, or the element of the power generation component itself is a stator carrier and / or a stator housing element. Alternatively, the element of the power generation component is defined to be a rotor carrier of a radial flux machine.

[0011] The laminations can, for example, have a thickness of 0.01 mm to 3 mm. They can be made of electrical steel. Furthermore, the laminations can each have an insulating layer on at least one side. Alternatively, insulating paper is specified between the respective stacked lamination layers.

[0012] The entire lamination stack may be provided with a coating consisting of an insulating material or an insulating adhesive, for example, with a coating thickness of 0.001 mm to 0.6 mm. The carrier lamination may, for example, have a thickness of 0.1 mm to 10 mm.

[0013] In one embodiment of the method, welding is specified to be performed through a lamination or body that carries the lamination.

[0014] One advantageous embodiment of this method specifies that the lamination stack consists of overlapping segments of a strip, or that the lamination stack consists of stacked individual laminations. The strip can be an electrical steel strip, also known as a "slinky". That is, the laminations can be individual laminations, or they can be segments of a common strip comprising a connecting lamination strip including multiple individual lamination segments. When the strip is wound in a spiral shape, the segments are brought into contact with each other, so that the multiple segments arranged in the connecting lamination strip overlap each other in a stacked manner, thereby forming the body of their respective stator teeth in their respective lamination stacks.

[0015] Welding can also be used to directly connect multiple laminations in a lamination stack. In particular, laminations that are directly adjacent to each other can be connected by welding, thereby establishing welded connections between laminations and between laminations and supporting laminations. Direct connection of laminations in a lamination stack can also be achieved by forming a weld rib between the laminations in the lamination stack.

[0016] One embodiment specifies that all the laminations of the lamination stack are welded together to each other and to the load-bearing laminations.

[0017] The carrier lamination may have at least one slit forming two edges, wherein the carrier lamination is connected to a plurality of laminations in a lamination stack by welding at at least one edge of the slit. In an advantageous embodiment, welding is specified at both edges of the slit, using a single weld if necessary. Here, the slit may be curved, and / or, in the case of an axial flux machine, the slit may be deviated from the radial direction, and in the case of a radial flux machine, the slit may be deviated from the axial direction.

[0018] In this implementation, a weld connects the two edges to each other, or a weld is made separately at each of the two edges.

[0019] In addition, a venting groove can be formed substantially parallel to the weld in the bearing lamination and / or lamination stack, so that the gas generated during welding can escape from the venting groove at least partially.

[0020] Welding can be performed at multiple welds in the load-bearing lamination, wherein the welds may be aligned parallel to each other and / or may not be aligned parallel to each other.

[0021] Welding can be performed at multiple welds in the load-bearing lamination, wherein the multiple welds are arranged circumferentially staggered and extend into a common radial region in at least some areas. This common radial region can also be considered as an annular region in which the multiple circumferentially staggered welds, whose extension direction has at least one radial component, extend into.

[0022] Regarding the shape of the weld, these multiple welds can also be formed into the shape of the single weld, wherein different weld shapes can be combined on a tooth or lamination stack.

[0023] The element manufactured according to the proposed method can be an element that extends substantially in a plane, arranged in the radial direction with its extending plane, to form a power generation component of an axial flux machine from which the stator teeth of the axial flux machine extend axially.

[0024] Here, the plane of the lamination is aligned perpendicular to the rotation axis of the rotor of the axial flux machine equipped with the element, and the weld seam is also radially extended at least in one component of its length direction.

[0025] Alternatively, the element may be a generally circumferentially extending, thus bow-shaped, or, if necessary, annular element, arranged coaxially around the rotational axis of the rotor of the radial flux machine equipped with the element, from which the teeth of the radial flux machine extend radially inward or radially outward.

[0026] Here, the plane of the lamination is also aligned perpendicular to the rotation axis of the rotor of the radial flux machine equipped with the element, and the weld here extends axially parallel to the rotation axis at least with one component of its length direction.

[0027] After welding, the load-bearing laminations can be fixed to a housing element by riveting, screwing, bonding, pressing, and / or welding. That is, the load-bearing laminations, together with the lamination stack, can be riveted, screwed, bonded, pressed, and / or welded to the housing element of the power generation component in subsequent processes. Accordingly, the housing element, together with the load-bearing laminations (on which lamination stacks are welded) fixed, then constitutes the element of the power generation component.

[0028] Another aspect of the invention is a power generation component of an electric rotating shaft, comprising at least one element manufactured according to a method for manufacturing a power generation component of an electric rotating shaft.

[0029] The power generation component can be configured such that: a support lamination has a protrusion facing the lamination stack, by means of which the support lamination rests against the lamination stack; for the purpose of cooling the stator, an external space through which fluid can flow is formed on the side of the protrusion; and / or the lamination stack has a groove on the side of at least one area where the support lamination rests against the lamination stack, for the purpose of cooling the stator, an internal space through which fluid can flow is formed on the side of the area where the resting lamination rests. The external space can also be referred to as an external cooling channel. At least one weld can be formed on the support lamination in the area where the protrusion rests against the lamination stack.

[0030] The protrusion can be achieved by pressing the bearing lamination, which creates a corresponding recess on the side of the bearing lamination opposite to the protrusion. When one or more welds are placed in this recess, an additional advantage is that the overlay of the welds will not extend beyond the upper surface of the bearing lamination, thus eliminating the need for additional installation space.

[0031] The internal space can also be called the internal cooling channel. In the area where the bearing lamination abuts against the lamination stack, at least one weld can be made in the bearing lamination.

[0032] The contact area of ​​the bearing lamination can be formed by the protrusion of the bearing lamination.

[0033] In addition, as mentioned above, a venting groove can also be formed in the load-bearing laminations and / or lamination stacks.

[0034] The power generation component can be the stator of an axial flux machine, or it can be the stator or rotor of a radial flux machine.

[0035] The present invention described above will be explained in detail with reference to the accompanying drawings, which illustrate preferred embodiments. The drawings are purely illustrative and do not constitute any limitation on the present invention, and it should be noted that the embodiments shown in the drawings are not limited to the dimensions shown.

[0036] These accompanying figures illustrate various aspects of the methods used to manufacture stator elements of an axial flux machine. That is, the element of the power generation component here is a stator element of an axial flux machine.

[0037] Figure 1-9 Different embodiments of the carrier laminations and the lamination stacks disposed thereon by welding are shown.

[0038] First, combine Figure 1-3 The description explains the common aspects of these implementation methods.

[0039] A lamination stack 20 is provided, comprising a plurality of laminations 21 arranged in a stack. A carrier lamination 40 is disposed on one side of the lamination stack 20. Figure 1-9Only one partial cross-section of each is shown in the figure.

[0040] Using one welding machine (in) Figure 1 (Using welding nozzle 12 as an example) Welding is performed along weld seam 13 on the support lamination 40 and the lamination 21 of the lamination stack 20. Through the completed weld 70, the lamination 21 of the lamination stack 20 is firmly connected to the support lamination 40. Here, in the illustrated embodiment, the laminations 21 are also fixed to each other. Welding 70 thus provides an element 10 of a power generation component, which includes a support lamination 40 on which the laminations 21 of the lamination stack 20 are fixed. Each lamination stack 20 substantially forms its own stator tooth 11, according to... Figure 1-9 The stator teeth are stator teeth of axial flux machines.

[0041] The following will be discussed. Figure 1-9 Differences between the embodiments shown.

[0042] Figure 1-3 One embodiment is shown in which one side of the lamination stack 20 is abutted against the support lamination 40 in a face-to-face contact manner.

[0043] exist Figure 4-7 An embodiment with an exhaust groove 60 is shown, wherein Figure 4 and Figure 5 The exhaust groove 60 of the first embodiment is shown, while Figure 6 and Figure 7 The venting channels 60 of the second embodiment are shown. Each venting channel 60 is used to vent welding gases, which are particularly likely to be generated when the laminations 21 of the lamination stack 20 have a coating. This can prevent or reduce the formation of unwanted porosity in the weld.

[0044] according to Figure 4 and Figure 5 In one embodiment, an venting groove 60 is provided on both sides of the completed weld 70 or the weld 13 formed therefrom in the bearing lamination 40.

[0045] according to Figure 6 and Figure 7 In one embodiment, in the lamination stack 20, an venting groove 60 is provided on both sides of the completed weld 70 or the weld 13 formed therefrom.

[0046] The depth of each vent groove 60 is sized such that the weld 13 can cross the gap between the upper surface of the lamination stack 20 and the supporting lamination 40.

[0047] Figure 8 A schematic diagram of the welding process for components used in manufacturing the power generation parts of the electric rotating shaft is shown, wherein an external space for cooling is provided. Figure 9A schematic diagram of the welding process for components used in manufacturing the power generation part of the electric rotating shaft is shown, wherein an internal space for cooling is provided. Both embodiments shown here also include the aforementioned venting channel 60.

[0048] Figure 8 One embodiment is shown in which the support lamination 40 has a protrusion 61 facing the lamination stack 20, by means of which the support lamination 40 abuts against the lamination stack 20. Thus, apart from the protrusion 61, a gap is maintained between the support lamination 40 and the lamination stack 20 in certain areas, thereby enclosing an external space 62 or external cooling channel through which a cooling medium can flow to cool the components of the power generation unit used in the electric rotating shaft.

[0049] Figure 9 A similar embodiment is shown, but a groove 30 is added to the side of the lamination stack 20 facing the supporting lamination 40. By having the supporting lamination 40 abut against the lamination stack 20, an internal space 31 or internal cooling channel is thus formed between the supporting lamination 40 and the lamination stack 20. This channel can also be through which a cooling medium flows to cool the components of the power generation unit. Figure 9 In the embodiment shown, the external space 62 and the internal space 31 are interconnected.

[0050] Furthermore, it can be seen that the bearing plate 40 has a corresponding recess on the side directly opposite the protrusion 61. Its advantage is that the overlay of the resulting weld 13 will not extend beyond the surface of the bearing plate 40, thus not requiring additional installation space.

[0051] Figure 10-15 Different embodiments of the lamination stack 20 are shown, wherein Figure 10-15 All embodiments shown are embodiments of the stator elements of an axial flux machine.

[0052] Figure 10-13 This illustration shows one embodiment of a stator element 10 as a power generation component, wherein stator teeth 11 are formed from lamination stacks 20 derived from winding strip or electrical steel sheet, the electrical steel sheet including a connecting lamination strip 23 in which individual lamination segments 22 are integrated, these segments 22 subsequently forming laminations 21 of their respective lamination stacks 20. That is, Figure 10-13 The embodiment shown is a so-called "Slinky", which is a wound stator.

[0053] The supporting lamination 40 is configured as an annular disk. The arrangement of the lamination segment 22 within the connecting lamination belt 23 is particularly evident from… Figure 11As can be seen, the stamping segment 22 is a component of the connecting stamping strip 23. Therefore, when the connecting stamping strip 23 is welded at the position of the stator tooth 11, the relevant stamping segment 22 will also be welded.

[0054] like Figure 12 As shown, multiple radially extending welds 13 have been formed in the bearing lamination 40 relative to a rotating shaft 1 (not shown) belonging to the stator element, by means of which the connecting lamination strip 23, and thus the lamination segments 22 contained therein, are welded to the bearing lamination 40 in the manner described.

[0055] Figure 14 and Figure 15 Another embodiment of the manufacturing of the stator element 10, which is a power generation component, is shown. Here, individual laminations 24 are arranged in a lamination stack 20, and these individual laminations 24 are not connected to each other by a connecting lamination strip 23. These individual laminations 24 are welded to the carrier laminations 40 as described above 70, thereby producing the individual lamination stack 20 as shown... Figure 15 The stator teeth 11 of the element 10 that forms the power generation component are shown.

[0056] Figure 16-20 Again, a separate diagram is shown for... Figure 10-15 The two embodiments shown are formed by welding connections, but with slight modifications. Figure 16-20 Only one section of the bearing lamination 40 is shown. Figure 16 and Figure 17 It shows according to Figure 10-13 The embodiment shown is a section of a lamination stack 20 that forms a stator tooth 11 and is provided on a bearing lamination 40.

[0057] Figure 18 and Figure 19 It shows according to Figure 14 and Figure 15 The embodiment shown is a section of a lamination stack 20 that forms a stator tooth 11 and is provided on a bearing lamination 40.

[0058] Figure 20 It shows Figure 16 and Figure 18 The cross-sectional view of the embodiment shown clearly shows the weld 70 along weld 13.

[0059] Each of the bearing laminations 40 here has at least one slit 50, which correspondingly has a first edge 51 and a second edge 52 extending parallel to the first edge 51, particularly as Figure 17 As shown.

[0060] When the distance between the two edges 51 and 52 is relatively small, an I-weld is performed as weld 13 between the two edges 51 and 52. A fillet weld is performed as weld 13 between each of the respective edges 51 and 52 and the lamination stack 20.

[0061] Contrary to the embodiments described so far, in these embodiments the laminations 21 of the lamination stack 20 are welded by means of the carrier lamination 40. Figure 16-19 The diagram shows that instead of welding through the bearing plate 40, the bearing plate 40 is made with a slit, and the corresponding slit 50 is used to perform one or more welds 13.

[0062] Figure 21-29 Different configurations of one or more welds forming a stator tooth lamination are shown. For clarity, individual labels / markings for the lamination laminations and welds have been omitted.

[0063] Figure 21 One embodiment is shown in which the weld extends radially across the lamination stack.

[0064] Figure 22 One embodiment is shown in which two welds extend radially across the lamination stack, parallel to each other and spaced apart from each other in the circumferential direction.

[0065] Figure 23 One embodiment is shown in which a weld extends across the lamination stack, deviating from the radial direction but having a significant radial component.

[0066] Figure 24 An embodiment with three welds is shown, which extend parallel to each other and into a common radial region 81.

[0067] Figure 25 Multiple welds performed in the form of short welds / spot welds are shown, which are performed in parallel to each other, wherein the welds that are adjacent to each other in the circumferential direction extend into a common radial region 81.

[0068] Figure 26 Showing with Figure 25 A similar implementation method, but short welds / spot welds are achieved along three welding paths.

[0069] Figure 27 One embodiment is shown in which two inclined welds that extend non-parallel to each other are implemented across the lamination stack.

[0070] Figure 28 Show Figure 24 and Figure 27The combination of the embodiments shown includes two welds that are inclined to each other and extend non-parallel, with a radially extending weld between them extending into a common radial region 81.

[0071] Figure 29 An arc-shaped weld is shown.

[0072] All the weld shapes shown here can be combined with each other.

[0073] Figure 1-29 The illustrated embodiment relates to a stator element of an axial flux machine, wherein the stator teeth are axially aligned with respect to the rotation axis of the associated rotor.

[0074] Figures 30-33 Another embodiment of element 10 of the power generation component is shown, which is provided as a stator element in a radial flux machine.

[0075] In this embodiment, the carrier lamination 40 is substantially made into a hollow cylindrical shape, wherein the lamination stack 20 forming the stator teeth 11—relative to the rotation axis 1 of the associated rotor shown—extends radially from the carrier lamination 40. Figure 30 A stator element is shown as a component 10 used to generate electricity, forming the stator of a radial flux machine that is an inner rotor. Here, stator teeth 11 are arranged radially inside the bearing laminations 40.

[0076] Figure 32 A stator element is shown as component 10, which serves as a power generation unit and forms the stator of a radial flux machine as an outer rotor. Here, stator teeth 11 are arranged radially outward of the bearing laminations 40.

[0077] As described above for the method of manufacturing a power generation component of an electric rotating shaft for an axial flux machine, here each stator tooth 11 is formed by a stack of laminations 20, which are assembled in a stack and are securely connected to a carrier lamination 40 by a weld 70 along the weld seam 13 shown.

[0078] In the embodiment shown here, the lamination 21 is further formed as an individual lamination 24. However, this embodiment is not limited to using individual laminations 24; the laminations can also be formed as segments disposed in a common connecting lamination strip 23, and subsequently overlapped during winding to form their respective lamination stacks 20, such as... Figure 10-13 As stated above.

[0079] Figure 33 A separate stator tooth 11 is shown, which is connected to the carrier lamination 40 by welding 70. The stator tooth 11 includes a winding 14 of conductor material surrounding it.

[0080] By means of the method proposed herein for manufacturing a power generation component for an electric rotating shaft, and a power generation component including a component thus manufactured, a technical solution is provided in which the fixation of individual laminations for forming tooth lamination stacks is achieved in a simple, cost-effective, and time-saving manner.
