Definitions
- the present invention relates to a method for producing a forming coil for insertion into a laminated stator core of a synchronous generator of a gearless wind energy plant. Moreover, the present invention relates to such a forming coil and a winding package having a plurality of forming coils. In addition, the present invention relates to a synchronous generator with such form coils or with such a winding package. Moreover, the present invention relates to a wind turbine.
- Gearless wind turbines have very slowly rotating generators.
- slowly rotating synchronous generators have proved to be advantageous, in particular ring generators.
- a generator to stiffen hen in which the magnetically active elements are arranged on a ring area around the axis of rotation of the generator.
- Such a synchronous generator has a stator which has a laminated core in which windings are received in grooves. During operation of the generator, voltages and thus currents are generated in these windings. Because such a synchronous generator for a gearless wind turbine is turning very slowly, e.g. approximately in the range of 15 rpm, it has a very high number of stator slots and thus stator poles. The number may be in the range of, for example, 48, 96, 192 or even higher. The manufacture or winding of such stators can thus be very complex.
- a method for producing a preformed coil according to claim 1 is proposed.
- Such a method of manufacturing a forming coil produces a forming coil which is prepared for insertion into a laminated stator core of a synchronous generator of a gearless wind turbine.
- such a shaping coil encloses six stator poles or stator teeth. It is then in a first and a seventh groove.
- this preformed coil is carried out in such a way that at least one flat printed conductor is first cut out of a metal sheet. Accordingly, this trace is as flat as the sheet from which it was cut out.
- the thus cutout conductor is then, for example, designed as a large U or similar, or designed as a part, in particular a half of a U. In the case of this U-shaped configuration, the two legs can be very long and very close to each other.
- the cut-out conductor tracks are bent so that a first groove track section for insertion into a first groove of the laminated core, a second groove track section for insertion into a second groove of the laminated core and at least one winding head section connecting the two groove track sections and to be arranged outside the grooves are formed ,
- the folding is done so that the two Nutbahn- sections are basically moved parallel to each other.
- one groove track section can be raised relative to the other groove track section become.
- the mold coil thus produced corresponding to a one-piece construction, which has been cut out of the sheet and brought into their shape by bending and thereby essentially represents a rigid component.
- many such form coils are now produced and connected to one another.
- the next shaping coil of this phase would therefore be inserted into the 13th and 19th grooves and the first groove track section of one of these two shaping coils would be electrically connected to the second groove track section of the second of these two shaping coils.
- a first phase former would be inserted into first and seventh slots, and next, a next phase former would be inserted into the second and eighth slots.
- One possibility for ensuring such juxtaposition, whereby the shaping coils can be successively inserted one after the other into the grooves, as described above, is by a corresponding shaping.
- One possibility of the shaping is that a part of the winding head section is offset by a width of the first or second groove track section.
- both the first and the second Nutbahnabites are the same width and also this staggered portion of the winding overhang portion is also so wide. To put it bluntly, this would result in a constellation in which the first shaping coil is inserted with its first groove track section into the first groove when it is inserted.
- this offset section of the winding head section projects beyond the slot opening of the stator.
- this section also projects beyond the unequipped section of the winding head section of the first shaping coil.
- the necessary crossing area can be created here, which is necessary in order to guide this second shaping coil from the second to the eighth groove and thus to cross the section of the first shaping coil which extends to the seven groove.
- successively the form coils can be inserted as already described above.
- the configuration of these winding head sections is thus possible very flat, so that this successive nested insertion is possible.
- a forming coil from a piece of sheet metal.
- This can also create a stable structure that can be mechanically stable and resilient.
- many identical form coils can be manufactured with only very small tolerances to each other.
- the transition between the groove sections over the winding head section can be designed to be very stable due to this one-piece construction.
- the form coil can alternatively be made of at least two composite sheet metal sections, in particular by a sheet metal section comprising a first Nutbahnabêt and the winding head portion and the second sheet metal portion comprises a second Nutbahnabites.
- These individual sheet metal sections can then, for example. After folding, be assembled. This can be done, for example, by screwing or welding. In this case, an increased effort to compound as well as any durability problems would be accepted by the assembly, but it can simplify the production of the individual parts.
- the Nutbahnabête each have a web surface. This web surface has formed a portion of a sheet surface of the sheet during or prior to being cut out of the sheet.
- the forming coil is now designed so that it is prepared for insertion into the laminated core, namely in the grooves, in a direction parallel to this web surface.
- the surface bears on one side of the respective groove or, at least in the state inserted into the groove, runs parallel to the side of the groove.
- a forming bobbin is then assembled from at least two such cut and partially folded groove track sections.
- four such Nutbahnabitese be assembled so that the form of coil is not only U-shaped, but also loop-shaped, so that therefore two Nutbahnabitese each lie in a groove.
- the Nutbahnabitese interconnected via the winding head portion are arranged plane-parallel to each other, namely as intended in different grooves and thus in different planes.
- the so interconnected Nutbahnabête so for example two or four, form the produced form of coil, which is designed to be rigid.
- Each groove track section preferably has a winding head part section.
- two Nutbahnabitese are connected in the region of their winding head sections, in particular they are welded together. This is done so that the two winding head part sections form the winding head section.
- the Nutbahnabitese are formed with their winding head portions so that the two winding head portions touch substantially in a region in which they are welded together before the Nutbahnabitese are used as intended in corresponding two grooves.
- Each groove track section thus has a Nutschen- angle, which runs in each case a groove, and at least one winding head portion section which extends outside of the groove.
- the cutting and folding thus creates sub-elements that are already adapted in their form to the use in the stator so that they can form a winding of the stator together with many other Nutbahnabitesen, which are also each inserted into their grooves.
- Nutbahnabitese are hereby welded together and inserted as a finished coil in each case 2 grooves.
- the sheet, which forms the starting material is made of aluminum.
- a forming coil is formed, and as a result, a winding of the stator made of aluminum.
- Aluminum is less electrically conductive than copper, so copper is usually preferred over aluminum.
- known machines are usually designed for the use of copper, because in the nominal operation of the machine, its temperature development is known. This knowledge of the temperature development is based on the known electrical properties, in particular the expected current and the resulting heat, especially in the copper windings. This heat must be dissipated by the design of the generator.
- higher heating is expected due to the higher specific resistance, which speaks against the use of aluminum. In particular, higher temperatures would be expected, on the discharge of the machine is not designed.
- the weight of such a generator with aluminum windings is significantly lower than when using copper, because although copper can achieve the same electrical conductivity with less cross-section, ie less volume, but copper has a much higher specific gravity. Due to the favorable filling factor by the provision of the proposed flat conductor tracks, a similar ohmic resistance of the winding can be achieved in a first approximation with these slot track sections made of aluminum in slots of approximately the same size, as in the case of the use of copper round wires.
- the cutting out of the conductor tracks or conductor track sections preferably takes place by means of water jet cutting or lasers.
- the groove track sections at least their groove legs, be separated into a plurality of parallel line sections become. Accordingly, several line sections are adjacent to each other, based on the sheet from which they are cut, so based on this flat orientation. When inserting into the respective grooves, however, these line sections lie one above the other, ie they lie one above the other from a slot base to a slot opening. Thus, they are layered in the radial direction and thus can prevent cross-currents in the radial direction, which can occur due to current displacement effects in the operation of the generator.
- This division into several parallel line sections can be done by water cutting or laser cutting and preferably this is done before folding.
- An advantageous embodiment also proposes that spaces between the parallel line sections of the separated Nutbahnabête receive an electrical insulation material.
- the single lanes are not very stable.
- the advantage of the sheet metal coil is to provide a geometrically exact and identical design of the winding heads with a large surface area and thus a good cooling property. This can be favored by such a casting.
- a first parallel line section extends from a first groove track section to a second groove track section, wherein such a line section changes its relative position in the respective groove, that is, from the one groove from the lower region or base region in the other groove to an upper groove Area, that is led to the opening area.
- a parallel line section in the winding head area which connects namely these two Nutbahnabête, deflected accordingly. Again, this may be advantageous in terms of consideration of current displacement effects.
- the parallel line sections of a slot track section preferably have different cross sections. This results in partially different conductances in different positions of the respective groove. This also takes into account that different strong currents can occur.
- the individual webs must be pulled through as electrically separate single webs, also in the area of the winding heads.
- these connecting elements between the form coils can be performed without single tracks.
- a shaping coil is also proposed, which was produced by a method according to one of the preceding embodiments.
- a winding package is also proposed that has a plurality of shaping coils according to at least one embodiment described above.
- the winding package preferably has a plurality of shaping coils and in each case a connecting section between two shaping coils, wherein the connecting section is produced by cutting out a flat line region from a metal sheet, in particular also from an aluminum sheet, and folding the flat conductive region so that it contacts two groove track sections for connecting the same can be attached. He is changed by the bending so that he can overlap several grooves between the two form coils. In particular, it will connect a groove track portion of the first die coil to a groove track portion of the second die coil. It overlaps, for example, the 8th to 12th groove when the one Nutbahnabêt is arranged in the 7th and the other groove portion of the other form of coil in the 13th groove, as would be the case with a 6-phase system.
- the connecting section preferably corresponds in its construction to the winding head section.
- a winding package which can also be referred to simply as a winding or overall winding of the stator, thus comprises all the necessary coils. In the fall of a 6-phase system, this winding package thus includes all six phases. This is generally true.
- a wound stator therefore presents itself in such a way that winding-head sections of the shaping coils protrude on both sides of the stator lamination stack.
- the connecting sections are present, namely one each between two form coils.
- a stator of a generator of a gearless wind power plant which has a stator with a laminated stator core.
- a winding package according to one of the embodiments described above is used. This can also be described as wound stator laminated core with a winding package according to one of the above embodiments.
- the grooves of the laminated stator core are rectangular in their cross-section, in particular without constriction of the intended opening to the air gap.
- the plate-shaped Nutbahnabitese can be inserted in a simple manner in the radial direction. It has been found that the expansion of the corresponding grooves has no significant effect on the behavior, in particular magnetic behavior of the generator. Especially a feared high ripple has not set in.
- this rectangular cross-sectional shape can be easily provided, and thereby it can be achieved to easily manufacture such a stator and corresponding generator.
- This also makes it possible to implement a higher degree of automation when loading.
- a synchronous generator of a gearless wind turbine is also proposed, which has a stator according to an embodiment described above.
- FIG. 1 shows a wind energy plant in a perspective view.
- FIG. 2 shows schematically in a side view a generator of a gearless wind energy plant.
- FIG. 3 schematically shows a stator of a generator of a gearless wind power plant in a side view.
- Figure 4 shows schematically a section of a stator of a generator of a gearless wind turbine with two inserted coil form.
- Figure 7 shows the two Nutbahnabitese of Figures 5 and 6 in a composite state to a first loop state.
- FIGS. 8 and 9 show third and fourth groove track portions of a forming coil.
- Figure 10 shows the two Nutbahnabitese of Figures 8 and 9 in a composite state to a second loop state.
- FIG. 11 shows a forming coil composed of the four groove track sections of FIGS. 5, 6, 8 and 9.
- FIG. 12 shows two form coils connected to one another via a connecting section, in each case according to FIG.
- FIG. 1 shows a wind energy plant 100 with a tower 102 and a nacelle 104.
- a rotor 106 with three rotor blades 108 and a spinner 110 is arranged on the nacelle 104.
- the rotor 106 is set in rotation by the wind in rotation and thereby drives a generator in the nacelle 104 at.
- FIG. 2 shows schematically in a side view a generator 1 with a rotor 2 with a rotor carrier 4 and a rotor pole region 6 which can rotate in the stator 10 of the generator 1 separated by an air gap 8.
- the stator 10 is held by a stator support 14 which, like the rotor support 4, is preferably star-shaped.
- a winding head 16 is also indicated on both sides. In this respect, the winding head is the area of the winding which in each case establishes a connection between individual grooves.
- FIG. 3 shows a non-wound stator 10 in a side view, which may also be referred to as an axial view.
- unwound grooves 12 There are also schematically shown unwound grooves 12.
- the grooves 12 alternate with teeth 18 and the teeth 18 are, together with a base portion 20 by layering many individual sheets, namely packet stacked to form a stator lamination formed.
- FIG. 4 now shows, in a perspective cutout, a laminated stator core 40 with a plurality of substantially rectangular cross-section grooves or stator slots 42.
- two exemplary former coils 44 are inserted and these two former coils 44 are connected to a connecting section 46.
- Figure 4 is an illustrative representation and does not necessarily reflect the order of filing of the stator lamination stack 40.
- the two form coils 44 shown form part of the winding of one of six phases.
- Both form coils 44 are each composed of four Nutbahnab mustarden 48. In each case two Nutbahnab mustarde or a part thereof, namely the groove legs 66 are received in one of the grooves 42.
- the same reference numeral, namely 48 is used here for the sake of simplicity, although the groove track sections 48 differ in some details, as can already be seen in FIG.
- Each Nutbahnabites 48 has at least one winding head portion 50, which are each disposed outside of the grooves 42. Two winding head sections 50 are each assembled to form a winding head section 52. This composition is achieved by welding at the weld 54.
- the winding head sections 52 very closely resemble the connecting section 46.
- the two differences are basically only that the connecting portion 46 attached to connecting legs 56 each to a Nutbahnabites, namely, are welded.
- the connecting section 46 has no weld seam, like the weld seam 54 of the winding head sections 52.
- FIGS. 5 and 6 now each show a groove track section 48.
- FIG. 5 has a winding head section 50 and a connection region 58.
- a connection to a connection section 46 is to be established at the connection region 58 or, in the case of the last form coil, a connection for electrical connection of the generator can be provided there.
- the Nutbahnabêt 48 of Figure 6 has two winding head portions 50, which are each to be connected to a winding head portion of a further Nutbahnabites, namely once with that of Figure 5 and the other with that of Figure 8.
- FIG. 7 shows the two groove track sections 48 of FIGS. 5 and 6 assembled. They are welded in their two winding head sections 50 at the weld 54. Accordingly, the winding head section 52 is also produced there.
- FIGS. 8 and 9 likewise show two groove track sections 48 and here the groove track section 48 of FIG. 8 has two winding head section sections 50 and the groove track section 48 of FIG. 9 has only one winding head section 50.
- FIG. 10 shows the connection of these two groove track sections 48 of FIGS. 8 and 9. Here, too, the connection takes place at the weld seam 54, so that a stable overall part is produced and the winding head section 52 is also formed.
- the shaping bobbin 44 has two lowered regions 62.
- This lowered region 62 is very marked on the left-hand side in FIG It is difficult to see in the right side, because it is covered by part of a groove track section.
- This lowered region 62 is achieved by a deflection section 64.
- This deflecting section 64 deflects the respective groove leg 66 of the relevant groove track section 48 downward accordingly.
- a groove leg 66 is here, and not only in the illustrated embodiment, the part of the Nutbahnabitess referred to, which lies as a straight portion in the respective groove. From here, the deflecting section 64 deflects the groove track section essentially downwards by a width of the groove leg 66.
- FIG. 4 shows two inserted shaping coils 44, which both belong to the same phase.
- the first form of coil 44 in the first groove N1 and the seventh groove N7 would be a form of coil 44, not shown here is, a next phase in the second groove N2 and the eighth groove N8.
- this form spool 44 not shown, must be crossed at the lowered portion 62 in the first and seventh grooves N1 and N7. This is made possible by this lowering of the lowered area 62. It can be seen that all the form coils 44, that is to say not only those of the first phase but of all phases, are thus initially used, in order subsequently to connect the form coils of the respective phases through the connection sections 46.
- the form coil shown in the figures namely sheet metal coil, has two turns. It therefore consists within a groove of two metal sheets, e.g. each 6mm. It may also be a coil with e.g. be realized five turns in the described technique by five sheet metal tracks are each 3mm in a groove.
- An essential idea of the invention is to use instead of wire sheet metal and to use the well automatable method lasers, or water jet cutting, edging and welding.
