Description

The invention relates to a new design of a bearingless generator, / motor preferably suitable for installation in a turbine, according to the described in the DP 44 40 241 C1 and GMA 20 2014 0039 turbine provided with a mechanical bearing known type, also as external driven, / driven unit can be used.

The purpose of the invention is the representation of a new generators, engine design, which can be driven over a wide speed range and their ironless coil system via a closed Magnetsystenm, (extension of the known since 1985 Halbach array) is excited. The coil segments of the generator / motor can be tapped arbitrarily or combined with one another to form any desired coil configurations.

The object of the invention is to provide a, easy to produce, suitable for high speeds, mechanically stable, ironless generator / motor design, the excitation coil is constructed modularly within a coaxial array of excitation magnets and which is easy to manufacture and variably connected. The magnet system should be removable for remagnetization.

The solution according to the invention should be nearly as small or large as possible with the same construction scheme and the number of effective magnetic poles as well as the number of winding loops should be adaptable to the power requirements.

Furthermore, the inventive solution should allow the production of generators, different performance by changing the length of the magnet array with the same cross-sectional dimensions.

Multi-pole permanent magnet shafts and rings for the production of electric motors and generators are from DE 66 03 272 as well as the 36 22 459 known. Also known are so-called Halbach arrays by the Writing by K. Halbach "Permanent Magnet undulators, Journal de Physique Coloire C1, supplement au No 2 Tone 44, February 1983 page C1-211 ,

In the US 5280209 a similar magnet arrangement is described and illustrated and described. In the US 725470 a similar magnet arrangement in the form of a coaxial Halbach array is described, which is used as a coupling. In the publication of the Helmholtz Zentrum Berlin: "Permanent Magnets including Wigglers ans Undulators", Johannes Bahrdt 20.-22.6.2009 On page 31 is also shown a similar magnet arrangement. The use of Halbach arrays for generator applications is for example from the DE 103 61 378 , of the CH 705 833 or the DE 10 2004 017 157 and others known. In the DE 10 210 054 170 and other patent applications of this applicant, a coaxial Halbach array is described.

Schwiering the above solutions are that they are intended for a predominantly static applications and the other for lack of adequate security of the magnets against ejection at high speeds, or occurring mechanical / acoustic vibrations are not secured and that in the publications no remagnetization of the permanent magnets used is provided.

The structure of the generator is described below and illustrated by examples in an overview and in successive sections.

The inventive generator consists of two modules.

The first assembly, referred to as a magnet assembly, is connected to the turbine rotor, 9.1 ), and consists of the generator housing, ( 1 ) into which the magnet array, ( 3 ), in detail the magnet segments, ( 3.1 ) and ( 3.3 ), and the magnetic shaft, ( 4.1 ), which in the cover screw, ( 2.2 ), by means of a conical seat and the nut, ( 4.13 ), is attached.

The permanent magnets used in this generator are preferably made of neodymium-iron-boride or cobalt-samarium. The surfaces of the individual magnets are galvanized, phosphated or bonded to protect the surfaces against oxidation, which is a variant of the phosphating.

The cover screw, ( 2.2 ), is in the turbine rotor, ( 9.1 ) or, for example, in a series production, part of the same. In the cover screw connection, ( 2.2 ), is in an annular groove an insert, made of a dielectric material with low dielectric damping, ( 2.3 ), which incorporates the transmission of eddy currents from the reverse domain, 6.3 ), which prevents coil segments on the rotor system and guides the cooling air from the inner to the outer air gap.

On the, the cover screw, ( 2.2 ), opposite side of the rotor is a ring nut, ( 2.4 ), the generator housing, ( 1 ), with the magnet array, ( 3 ), fixed.

The radial coupling of the magnet array relative to the rotor takes place by means of drivers in the inner and outer contour of the generator housing, 1 ), in the example shown as driving pins, ( 1.3 ), which are half in longitudinal grooves, ( 1.1 ), and ( 1.2 ), the inner and outer diameter of the generator housing and with the other half in longitudinal grooves, ( 9.4 ). of the turbine rotor and a part of the magent segments, ( 3.1 ), and ( 3.5 ) are mounted. In a mass production, the generator housing, ( 1 ), together with the drivers, ( 1.3 ) and ( 1.4 ), manufactured as precision casting, wherein the driver structures may also have a different shape.

The coil segments and the coil carrier, ( 5.2 ), are with the ring board, ( 6.1 ), firmly connected and by screws, ( 10.2 ), with the fixed turbine housing, ( 10 ), connected. Other variants of the coils are in 11 and 13 shown.

The entry of the cooling air takes place via the inner diameter of the annular plate, ( 6.1 ), through the inner air gap, ( 6.5 ), through the annular groove of the dielectric insert, ( 2.3 ), and the outer air gap, ( 6.4 ) to the segmented air outlets on the outer circumference of the ringboard, ( 6.1 ), or the inner contour of the turbine housing, ( 10 ).

In the inner diameter of the turbine rotor, ( 9.1 ), are takers, ( 9.4 ), for the drivers, ( 1.4 ) incorporated. These cam grooves correspond to the, on the outer peripheral surface of the generator housing, ( 1 ), inserted driving pins, 3 , ( 1.4 ), and cause the entrainment of the generator housing, ( 1 ), during the rotational movement of the rotor, ( 9.1 ).

On both sides of the inner diameter of the turbine rotor, ( 9.1 ), are fastening threads, ( 9.3 ), for receiving the cover screw, ( 2.2 ) and the ring nut, ( 2.4 ) incorporated.

In the inner diameter of the generator housing, ( 1 ), are the magnets of the magnet array, 3 , ( 3 ), and by the drivers, 3 , ( 1.3 ), in the inner driving grooves, 3 , ( 1.2 ), secured against twisting. The position of the passengers, 3 , ( 1.2 ), and the inner driver, 3 , ( 1.3 ), on the inner peripheral surface of the generator housing, ( 1 ), correspond to the driving grooves in the magnet segments, 4 , ( 3.1 ) and ( 3.5 ).

The generator housing, ( 1 ), with the magnet array, ( 4 ), is between the cover screw, ( 2.2 ), and the ring nut, ( 2.4 ), in the inner diameter of the rotor, ( 9.1 ), fixed.

In the cover screw is an insert, ( 2.23 ), used with an annular groove of a dielectric material, the generator housing, ( 1 ), has in the outer and inner contour longitudinal grooves, ( 1.1 ) and ( 1.2 ), into the drivers, ( 1.3 ) and ( 1.4 ) are used. The magnets of the magnet array, ( 3 ) are shown radially separated for better distinctness. The, in the magnetic wave, ( 4.1 ), used magnetic wedges, ( 4.3 ) and ( 4.4 ), are shown radially offset from this.

The fan wheel, ( 4.5 ), has at its periphery a blade structure for conveying the cooling air into the air gap between the magnet and the coil. It consists of a dielectric material and is fixed by means of the screw, 4:51 ), fixed in the magnetic shaft, with which the magnetic wedges, ( 4.3 ) and ( 4.4 ), in the axial direction against the cover screw, ( 2.2 ) are fixed.

In the ring nut, ( 2.4 ), is an insert, ( 2:42 ), made of a dielectric material with low dielectric damping, whose inner contour is provided with a structure, by which during rotation of the rotor, ( 9.1 ), the extraction of air from the air gap, ( 6.4 ), is accelerated. The ring nut, ( 2.4 ), fixes the magnets of the magnet array, ( 3 ), against cover screwing, ( 2.2 ), and prevents the displacement thereof in the longitudinal axis.

Inside diameter of generator housing, ( 1 ), are the magnets of the magnet array, 3 , ( 3 ), and by the driving pins, 3 , ( 1.3 ), in the inner driving grooves, 3 , ( 1.2 ), secured against twisting. The position of the passengers, 3 , ( 1.2 ), and the inner driving pins, 3 , ( 1.3 ), on the inner peripheral surface of the generator housing, ( 1 ), correspond to the driving grooves in the magnet segments, 4 , ( 3.2 ) and ( 3.5 ). The magnetic array, ( 3 ), and its interaction with the magnetic wave, ( 4.1 ), and their magnets, ( 4.3 ) and ( 4.4 ), as well as the coil, ( 6 ), is in 7 to 10 shown in detail.

The pole-forming magnets, ( 3.2 ) and ( 3.5 ), the external Halbach array, ( 3 ), as well as the magnets, ( 4.3 ), and ( 4.4 ), the magnetic wave, ( 4.1 ), are marked. Their function is in 7 to 9 described.

The magnetic wave, ( 4.1 ), and the associated magnetic wedges, ( 4.3 ) and ( 4.4 ), are in 3 radially apart and in 5 , shown in detail. At the magnetic shaft, ( 4.1 ), is a fan, ( 4.5 ) made of a dielectric material with low damping, by means of the screw, ( 4:51 ), with which the magnetic wedges, ( 4.3 ) and ( 4.4 ), in the axial direction against the cover screw, ( 2.2 ) are fixed. The magnet shaft and its variants are in 5 shown in detail.

5 to 5c show the magnetic shaft with inserted magnetic wedges. The magnetic wedges are preferably based on a square basic cross-section, (B) and (H). They sit diagonally to the center of the generator, in longitudinal grooves of the magnetic shaft and are protected by their geometry, the width of the overhangs (BMF), against ejection during operation.

The magnetic wave, ( 4.1 ), like the generator housing, ( 1 ), preferably of a non-alloy steel (eg St70 or St60), and is coated on its surface to prevent corrosion.

Galvanizing as well as phosphating can be used as the coating. In a mass production, the magnetic shaft is manufactured as precision casting and mechanically reworked on the required areas, (cone, thread).

The effective exit area of the magnetic field can be easily adjusted to the in. Value by adjusting the free circumferential component (BMF: BMK) 8th operating conditions described in that the distance of the center of the magnetic profiles, ( 4.3 ), and ( 4.4 ), and the associated inner profiles of the magnetic shaft, ( 4.1 ), to the center of the magnetic wave, ( 4.1 ), can be varied.

5a shows a section through the, in 5 represented magnetic wave, ( 4.1 ) and the magnetic profiles, ( 4.3 ) and ( 4.4 ). In this design form the magnetic profiles, ( 4.3 ) and ( 4.4 ), with the peripheral surface of the magnet shaft, ( 4.1 ), a closed surface. This arrangement has the advantage that manufacturing tolerances of the magnetic shaft, ( 4.1 ) and the magnetic wedges, ( 4.3 ) and ( 4.4 ), after assembly can be compensated by the fact that the complete assembly can be revised by cylindrical grinding, preferably the outer cone, ( 4.11 ) is used as a receptacle during the grinding process.

5b shows a simplified arrangement of in 5a represented magnetic wave, ( 4.6 ). The magnetic wedges shown here, ( 4.61 ) and ( 4.62 ) have a square basic cross section, (B: H), and are rounded or flattened at the peripheral region by a radius or a surface which is formed by a chord in the region (BMK) and the outer diameter of the magnetic wave, ( 4.6 ) equalized. By the, at the circumference between the Magentkeilen, ( 4.61 ), and ( 4.62 ), and the magnetic wave, ( 4.6 ), resulting longitudinal grooves an additional promotion of the cooling air is effected during operation.

5c shows a further variant of the magnetic wave, ( 4.7 ), which is hollow in the interior. This design is used in particular for systems with larger coil diameters, (from about 60 mm), for use. Here, the use of symmetrically formed magnetic wedges, ( 4.71 ) and ( 4.72 ) possible, which greatly simplifies their production and assembly and reduces the manufacturing cost. The magnetic wedges shown here preferably have a square basic structure, (H: B), and are provided on the pole faces, (F), symmetrically with faces, (BMK).

With increasing diameter coils and thus the magnet arrays of the hollow magnetic shaft, the radii on the peripheral surfaces of the magnetic profiles and the magnet segments can be replaced by flat surfaces.

6 shows a longitudinal section through the generator and a part of the rotor with the position of the individual parts.

The cover screw with ring groove, ( 2.2 ), In the example shown is made of metal, z. B. aluminum. In the annular groove of the cover screw is an annular dielectric insert, ( 2.23 ), with a likewise annular groove, ( 2.24 ), incorporated to guide the cooling air. The use of a dielectric material (eg, POM) prevents eddy currents from the coil during operation, 6.3 ), on the cover screw, ( 2.2 ), be transmitted. Alternatively, the cover screw in one piece, ( 2.1 ), made of a dielectric material, for example of a fiber-stabilized epoxy resin.

Both variants of the cover screw connection, ( 2.2 ), and ( 2.1 ), have an inner cone, ( 2.22 ), in which the magnetic wave, ( 4 ), by means of the mother, ( 4.13 ), is attached. The cover screw, ( 2.2 ) or ( 2.1 ), by means of thread, ( 2.11 ), in the turbine rotor, ( 9 ). fixed.

In the, in 6 represented magnetic wave, ( 4 ), are the magnetic wedges, ( 4.3 ), and ( 4.4 ). The magnetic wedges, ( 4.3 ), and ( 4.4 ), in the axial direction by the fan, ( 4.5 ), which with the screw, ( 4:51 ), in the magnetic wave, ( 4 ), is attached, against the cover screw, ( 2.2 ), or ( 2.1 ), fixed. In the radial direction, the fixation of the magnetic wave, ( 4 ), by the recording cone ( 2.12 ).

In the radial direction, the fixation is carried out by the drivers, ( 1.3 ).

Another way to fix the magnet array is that the pre-assembled array, together with the generator housing 2 , ( 1 ) is shrunk into the rotor, wherein an additional compression of the magnet array, 3 , ( 3 ), takes place.

7 shows a schematic arrangement of the generator, which in 8th and 9 is more detailed.

The generator housing, ( 1 ), is on outer and inner diameter with drivers, ( 1.3 ), and ( 1.4 ), which has a radial locking of the magnet array, 3 , ( 3 ), cause.

According to the rules of the structure of a Halbach array, the formation of magnetic poles, (pole change in the array) takes place in that, for. B. several magnetic profiles are joined together, whose magnetization direction (marked by arrows) is rotated by the part of the number between the poles to be formed. In the example shown, these are, viewed clockwise, up to the pole change four magnetic profiles, magnetic segment 0 ° with groove, ( 3.1 ), Magnetic segment 45 °, ( 3.2 ), Magnetic segment 90 °, ( 3.3 ), Magnetic segment 135 °, ( 3.4 ), Magnetic segment 180 ° with groove, ( 3.5 ), whose magnetization direction is rotated by 45 °. If this sequence, as shown, by other magnetic profiles, magnetic segment 225 °, ( 3.6 ), Magnetic segment 270 °, ( 3.7 ), Magnetic segment 315 °, ( 3.8 ), Magnetic segment 0 ° with groove, ( 3.1 ), continues, results in a rotation of the magnetic field by 360 °, with the lying between the poles magnetic profiles, magnetic segment 45 °, ( 3.2 ), Magnetic segment 90 °, ( 3.3 ), Magnetic segment 135 °, ( 3.4 ), and magnetic segment 225 °, ( 3.6 ), Magnetic segment 270 °, ( 3.7 ), Magnetic segment 315 °, ( 3.8 ), with regard to the emission of magnetic fields towards the inner diameter, largely neutral behavior. The radiation at the outside diameter is controlled by the generator housing made of iron ( 1 ), prevented. In the example shown, three assemblies joined together radially, as described above, form a closed group of several composite Halbach arrays.

The arrangement produced in this way corresponds to the magnetic wedges, 4.3 ), and ( 4.4 ), the magnetic wave, ( 4 ), and together with you form closed magnetic circuits, as in 8th shown.

In the 9 and 10 to 13 described coils consist of segments, ( 6:33 ) and ( 6:35 ), which are firmly connected to the coil carrier by gluing. In the 7 shown segments, ( 6:33 ) and ( 6:35 ), which is in 12 shown skew coil.

8th shows the in 7 shown arrangement, but without housing and driver. The description of the parts corresponds to the description in 7 , The figure shows the formation of the closed magnetic circuits, ( 3.9 ). and the magnetic flux, ( 3.10 ), a single coil segment, ( 6:33 ) the in 12 shown coil, as they result from the arrangement of the parts.

8a shows the section, (A1) 8th , The average width of the magnet segments, (BMS), should be determined from the difference between the inscribed circle and the perimeter of the magnet array, (HMS) with regard to the production and function of the height of the magnet segments (FIG. 3 ), results in being approximately square.

In order to achieve optimum induction of the coil segments for the operation of the generator, the tuning of the width of the magnetic flux (BMF), which is subject to a Gaussian distribution curve by the adaptation of the width (BMS), of the pole-forming magnet segments, ( 3.1 ) and ( 3.5 ), - like in 8a , Section, (A1) off 8th shown, to the width of the pole faces of the magnetic wedges, (BMK), within limits.

9 and 9a show the section, (A2) 8a , In 9 is a section through the coil carrier, ( 6.2 ) and a coil segment, ( 6.3 ), the, in 12 described oblique coil as an example in detail. This example applies to the construction of the coil segments, for all coil variants described here. The part of the coil segment lying outside the bobbin carrier, ( 6:32 ), is against the inner part of the coil segment, ( 6:34 ) offset by one coil segment width. During rotation of the assembled turbine rotor, ( 9 ), with the magnetic assemblies as in 1 and 6 shown, the inner and the outer regions of the individual coil segments are alternately traversed by the magnetic field.

The magnet array with the magnet segment, ( 3.1 ), is arranged outside the coil so that between, with the coil carrier, ( 6.2 ), glued, outside the bobbin, ( 6.2 ), arranged parts of the coil segments, ( 6:32 ), and the inner diameter of the magnet array, ( 3 ), a sufficiently large air gap, ( 6.4 ), is formed for the passage of the cooling air.

The magnetic shaft with the magnetic wedge, ( 4.3 ), is arranged inside the coil so that between, with the coil carrier, ( 6.2 ), glued, inside the bobbin, ( 6.2 ), arranged parts of the coil segments, ( 6:34 ), and the outer diameter of the magnet shaft, ( 4.3 ), a sufficiently large air gap, ( 6.5 ), is formed for the passage of the cooling air.

10 . 10a and 10b show the structure of the recording for the, in 11 . 12 , and 13 described coil variants, for installation in the turbine housing, 1 ( 10 ). is optimized.

It consists of a tubular coil carrier, ( 5.2 ) composed of a densified dielectric material, preferably an epoxy, or polyester resin reinforced by glass, aramid or basalt fibers. (When using basalt fiber, it should be noted that the base material for production is largely free of iron). In a mass production, the coil carrier can also be made of other, for the operating conditions, suitable dielectric materials, as far as they are free of magnetizable portions.

The bobbin is at one end with foot segments, ( 5.21 ), which in corresponding arcuate mounting slots, ( 5.16 ), the ring board, 10a , ( 5.1 ), and connected with this by a bond.

The ring board, ( 5.1 ), for example, consists of a glass fiber reinforced epoxy resin as it is used for the production of electronic circuit boards. It has, preferably at the outer edge for receiving the torque holes ( 5.13 ), for screwing the finished coil with the turbine housing, 1 , ( 10 ). At the outer periphery are segmented cutouts for the outlet of the cooling air, which through the inner opening, ( 5.14 ), the ring board, ( 5.1 ), is sucked.

Inside and outside of the circle, which through the arcuate mounting slots, ( 5.16 ) are formed in the ring board, ( 5.1 ), through-plated holes, ( 5.11 ), and ( 5.12 ), whose number and position with the coil segment arrangement of the coil used, ( 11 to 13 ), is tuned.

On both sides of the ring board, ( 5.1 ), optional conductor tracks for connection, (summary / connect in series), individual coil segments may be applied to a coil group or electrical taps, which are suitably galvanically reinforced. The principles described here apply mutatis mutandis to the, in 11 to 13 described coils.

10b , For exact guidance during assembly of the coils, ( 11 to 13 ), the inner and the outer peripheral surface of the bobbin, ( 5.3 ), as in 10b shown with Guide ribs are provided in which the coil-forming strands are inserted, which simplifies the assembly and fixation of the coil segments, especially in the production of prototypes. For coils, according to the in 11 illustrated variant, these guide ribs receive a twist of the intended design of the coil segments following.

In the 11 . 12 , and 13 , coil segments shown correspond in their conductor cross-section accordingly, 9 and 9a shown coil segment. The individually illustrated coil segments, 11a . 12a , and 13a , are made of, coated with insulating lacquer copper wire, or copper-coated aluminum wire coated with a baking lacquer layer. The back paint wire consists of a copper or a copper-coated aluminum wire whose surface is provided with a multi-layered cured insulating layer. On this insulating layer, a further hot melt adhesive layer, usually applied in a layer thickness of 2% to 5% of the wire diameter, in which, for example, in the coating finely ground mica or so-called micro-balloons can be mixed. Micro-balloons are hollow spheres made of glass or quartz glass which are manufactured in sizes from 2 μm. These admixtures act as spacers between adjacent wires when pressing the assembled coils. Are also known after application of the insulating layer, for example, with silk wound, and impregnated with baked enamel wires.

The coil segments are made of right and left twisted strands, in the raw form as a braid-like braid, with approximately square cross-section, made so that the individual strands, 9 , ( 6:38 ) and ( 6:39 ), twisted right and left are guided in pairs through the braided strand. It should be noted that in the majority of the braided strand, the adjacent strands have an opposite twisting direction. The twist length of the individual strands, ( 6:38 ) and ( 6:39 ), corresponds to one or more full revolutions to the length of the area through which the magnetic field flows (the length of the magent segments, / wedges). The strands are braided so that through the majority of the braid through left and right twisted strands are mutually adjacent.

Since such a mesh is not dimensionally stable when handling the individual coil segments, a thin strand (roving) of a dielectric fiber material (glass, aramid or basalt fiber) is preferably guided in the center of the strand or between several individual strands around which the strands are braided. This stranding (rowing) serves to maintain the length of the coil segment in the following molding processes.

After the blanks of the coil segments are cut to the required length, the ends are protected against delamination, preferably by cold welding under the action of ultrasound, wherein the connection contours, ( 6.31 ), respectively. ( 6:37 ), for the holes in the ring board with molded.

The application of ultrasonic welding for the production of electrical connections has been known since the 1960's from the connection technology of ribbon cables with printed circuit boards in the automotive industry. In the ultrasonic welding process, which in this case takes place expediently in a shaping die, the individual wires / strands to be gathered together are joined together by cold welding within a short time. Materials such as copper and aluminum are particularly suitable for this purpose. Experience has shown that removal of the insulation is not necessary for this process since the existing insulation in this process is displaced or vaporized in the area of the tool action.

The so formatted on length braided strands for the preparation of the coil segments are inserted into a heatable shape which corresponds to the outer geometry of the coil segments and heated very briefly under pressure, wherein the lying in the outer region of the strand layers of the backcoat layer form a connection with each other , which stabilizes the geometry of the strand for further handling and after cooling reproducible, further processable moldings, 11a . 12a , and 13a , form, which can be processed automatically.

These moldings are placed on the bobbins, 6.2 ) 7.2 ) or ( 8.2 ), fixed and with the associated connections. (Pads), the ring boards, ( 6.1 ) 7.1 ) or ( 8.1 ), connected. Subsequently, the preassembled coil segments are pressed in a heatable pressing device against the inner and outer peripheral surface of the bobbin, wherein for the individual coil segments compacted cross sections are formed, as in 11b . 12b and 13c shown.

The transition area, ( 8:32 ), and ( 8:36 ), together with the ring board, ( 8.1 ), and the coil carrier, ( 8.2 ), shed by means of an epoxy or polyester resin, wherein the complete coil assembly is firmly connected. Optionally, the cross sections of the individual coil segment or the left and right twisted conductors or the individual strands of the coil segments can be tapped separately but this is associated with a much higher cost in the production of the ring boards and the assembly of the coil segments and additional Lötaugenkreise from Ring board inside and outside the existing Lötaugenkreise requires.

An essential prerequisite for the function of the generator is that the, of the magnetic field-traversed areas of the coils (coil segments), during the manufacturing process, in particular during compression on / retained in the bobbin the given geometry and not, z. B. during compression of the coil segments on the bobbin course deformations obtained, which are caused by the twist of the strands within the coil segments. This is ensured by the spin-neutral design described here.

Instead of the above-described braided strands, it is also possible to use what are known as high-frequency strands of baked-lacquer wire for producing the strands. This ladder design has been known for a long time. It consists of a core, z. B. right-twisted strands and a sheath linksverdrallter strands, the proportion of left and right-twisted strands is the same. Due to the difference structure, however, can be in the pressing of such conductors of in 9a as in 11b . 12b and 13c do not reach shown filling level.

The protruding reverse areas at the head of the coil segments are, depending on the direction of rotation of the turbine rotor. ( 9.1 ), so arranged that the movement of the cooling medium, in the example described air, is sucked through the inner air gap at the entrance of the inner diameter of the bobbin and discharged through the outer air gap back to the environment by their skew, is accelerated. Further details of the coil segments and their manufacture are in the description of the coils, 9 and 11 to 13 called.

11 shows a coil arrangement whose individual coil segments, ( 8.3 ), from, outside the bobbin carrier, ( 8.2 ), lying strand, ( 8:33 ) within the bobbin carrier, ( 8.2 ), lying strand, ( 8:35 ), V-shaped, 11a , are therefore referred to as a V coil. This coil form is particularly suitable for use with flat / wide geometry strings in conjunction with a smaller number of coil segments on the circumference of the spool carrier. In the 11 and 11a shown coil segments, ( 8.3 ), (approximately square cross-section), correspond to the aforementioned state of prefabrication.

In operation, the magnetic field is simultaneously induced in several coil segments, but only in a part of the individual coil segment.

The individual coil segments, in the example shown twenty-four, are in the axial direction with a twist over the outer peripheral surface of the coil carrier, ( 8.2 ), which, in the reverse domain, ( 8:34 ), ie the area of the coil segment, which is guided over the end of the coil carrier, ( 8:34 ). The size of the helix angle depends on how many sectors of the pitch, in the example shown, 11b , two sectors each with 15 °, overlaps.

In 11b are the cross-sectional ratios of your individual coil segment shown after pressing on the bobbin. In the example shown, the coil segments overlap from the outer connection region, 8.31 ), to the reverse area, ( 8:34 ), an angle sector of 15 ° and the reverse region, ( 8:34 ), to the inner terminal area, ( 8:37 ), another angle sector of 15 ° of the connections on the ring board, ( 8.1 ). This area can be extended to other angular sectors, whereby the resulting bridge in the reverse of the coil segments bridges increase the space requirement in this area. In the 11b shown coil segments (flattened cross-section), correspond approximately to the state in the state after hot pressing of the coil elements on the bobbin. Pressed / compacted are mainly the induction-subjected areas of the coil segments, ( 8:33 ), and ( 8:35 ), as well as their reversal area, ( 8:34 ). The transition areas, ( 8:32 ), and ( 8:36 ), serve as buffers to compensate for manufacturing and assembly tolerances to the connection areas, ( 8.31 ), and ( 8:37 ), in the associated pads, ( 8.11 ), and ( 8.12 ), the ring board, ( 8.1 ). The transition area, ( 8:32 ), and ( 8:36 ), together with the ring board, ( 8.1 ), and the coil carrier, ( 8.2 ), shed by means of an epoxy or polyester resin, wherein the complete coil assembly is firmly connected.

12 one shows a coil arrangement whose individual coil segments are guided obliquely from the strand lying outside the bobbin carrier to the strand lying inside the bobbin carrier over the end of the bobbin holder, therefore as an oblique bobbin, 6 ). is designated.

This coil form is particularly suitable for use of a larger number of coil segments, ( 6.3 ), resulting in short induction pulses and a higher signal frequency than in the, in 11 described V coil, in conjunction with a larger number of coil segments on the circumference of the bobbin.

In the 12 and 12a shown coil segments, ( 6.3 ), in the example shown forty - eight. (with approximately square Cross section), correspond to the aforementioned state of prefabrication. In 12b are the cross-sectional ratios of your individual coil segment shown after pressing on the bobbin.

The coil segments, ( 6.3 ), are mounted so that the patted, preformed strand from the outer terminal, ( 6.31 ), axially along the outer peripheral surface of the bobbin holder, ( 6.2 ), to the reverse area, ( 6:34 ), and of this by a coil segment width, in the example shown 7.5 °, offset in the axial direction to the inner, in the example shown offset by 7.5 °, inner terminal, ( 6:35 ), the ring board, ( 6.1 ), to be led.

In the illustrated example, the coil segments from the outer connection region to the inner connection region each overlap an angular sector of the connections. This area can be extended to other angular sectors, thereby resulting in the reversal of the coil segments bridges that increase the space requirement in this area.

The transition area, ( 6:32 ), and ( 6:36 ), together with the ring board, ( 6.1 ), and the coil carrier, ( 6.2 ), shed by means of an epoxy or polyester resin, wherein the complete coil assembly is firmly connected.

13 shows a coil arrangement whose individual coil segments executed by, lying outside the bobbin strand to run inside the bobbin strand executed in pairs crossed are therefore referred to as cross-wound bobbin.

In the illustrated embodiment, the coil segments, ( 7.3 ), and ( 7.4 ), as previously described symmetrically preformed. They overlap each other within the angular sector of 7.5 ° each other. The crossing takes place in the reverse region, the coil segment (FIG. 7.4 ) to make the coil segment cross-section longer than the coil segment, ( 7.3 ). Apart from the resulting overall length, the coil segment is ( 7.4 ), a mirrored variant of the coil segment, ( 7.3 ).

During assembly, the coil segment ( 7.3 ), from the outer terminal area, ( 7.31 ), about the transition area, ( 7:32 ), and axially on the outer peripheral surface of the bobbin, ( 7.2 ), lying strand, ( 7:33 ), to the reverse area, ( 7:34 ), and obliquely guided over the same, ie by a sector width, (7.5 °), offset, to the inner peripheral surface of the bobbin holder, ( 7.2 ), and on this to the inner transition region, ( 7:36 ), and to the inner terminal area, ( 7:37 ).

In 13c are the cross-sectional ratios of your individual coil segment shown after pressing on the bobbin.

The coil segment, ( 7.4 ), from the outer terminal area, ( 7.41 ), about the transition area, ( 7:42 ), and axially on the outer peripheral surface of the bobbin, ( 7.2 ), lying strand, ( 7:43 ), to the reverse area, ( 7:44 ), and diametrically opposite, obliquely across the inversion area, ( 7:34 ), the coil segment, ( 7.3 ), ie, by one sector width, (7.5 °), offset to the inner circumferential surface of the bobbin holder, ( 7.2 ), and on this to the inner transition region, ( 7:46 ), and to the inner terminal area, ( 7:47 ).

This coil form has in the example shown twenty-four coil segment pairs and allows the paired mounting of the coil segments in the construction of the coil and is particularly suitable for using a larger number of coil segments, resulting in operation short induction pulses and a higher signal frequency than in, in 11 described V coil, in conjunction with a larger number of coil segments on the circumference of the bobbin.

The transition areas, ( 7.31 ) 7.31 ), such as ( 7:37 ) and ( 7:47 ), after assembly together with the ring board, ( 7.1 ), and the coil carrier, ( 7.2 ), shed by means of an epoxy or polyester resin, wherein the complete coil assembly is firmly connected. Optionally, the remaining coil surface can be included in the casting, but this can affect the heat dissipation from the coil segments.

The function of the generator in conjunction with the turbine described in DP 44 40 241 C1 and in GMA 20 2014 0039 will be described as follows.

The arranged in the turbine rotor coaxial magnet arrangement is, as in 1 shown connected to the turbine rotor. The coil, ie one of, in 11 . 12 or 13 shown coil forms is bolted to the fixed housing of the turbine.

Upon rotation of the rotor, which, between the pole-forming magnet, 8th , Coil segments located the magnetic flux thereof, wherein in the, located in the induction region magnetic segments, a voltage is induced, which can be tapped at the terminal portions of the coil segments.

Within the coil arrangements shown, the individual coil segments can be interconnected by bridges and be tapped together according to the pole pitch of the magnet array used.

The preparation of the generator is suitably carried out in an approximately square design, ie the diameter of the coil holder, 5 , and the length of the magnet segments, 4 , ( 3 ), and the magnetic wedges, ( 4.3 ) and ( 4.4 ), are about the same.
