Superconducting Furaiho I Lumpur currently being developed have the entire apparatus to the vacuum. The flyhole is a top type. For this reason, the rotation axis is likely to be shaken by the Euler equation of motion. Further, the conventional apparatus has a problem that it is large and complicated in structure.
Also, with the vertical rotating body supported at the stable rotational position by the control type radial magnetic bearing and the control type axial magnetic bearing, the superconductor is cooled and the superconducting bearing is activated, and the superconducting bearing and the radial magnetic bearing are used.

According to the present invention, the following effects can be achieved.
(1) The rotating body is stably rotated as a magnetic top by the action of the magnet at the center of the levitation magnet and the ring-shaped magnet surrounding it, and the stability of the cylindrical power generator that is levitated by the high-temperature superconductor is improved. be able to.
(2) The structure for the stable rotation drive is simple.

  (3) The weight and magnetic force of the generator rotor can be adjusted. Up to now, precise calculation of magnetic force has been required at the ordering stage, but the weight of the rotating body is the most important point in the superconducting levitation generator because the weight of the rotating body is closely related to the levitation force. If the weight of the magnet can be adjusted, levitation can be experimented first.

The cylindrical power generator levitated by the high-temperature superconductor according to the present invention includes a central magnet disposed in the central portion of the lower portion in the vacuum vessel, and the central portion disposed so as to surround the central magnet. A levitation magnet composed of a ring magnet having a different polarity from that of the magnet, and a drive / power generation magnet having poles alternately arranged in a row on the inner surface of the vacuum vessel above the levitation magnet; A circular levitation high-temperature superconductor disposed opposite to the lower portion of the cylindrical body, a driving coil installed outside the vacuum vessel, and a power generation coil installed outside the vacuum vessel, Lifting the vacuum vessel, giving a gap between the high-temperature superconductor for levitation before cooling, cooling the high-temperature superconductor for levitation, causing pinning, removing the gap, and lowering the vacuum vessel Floating the cylinder After the driving / power-generating magnet is rotated by the driving coil and a certain rotational force is applied to the cylindrical body, the center magnet of the levitation magnet and the ring-shaped magnet due to the inertia of the cylindrical body stably rotate driven as magnetic frame by the action of the magnet and the levitating high temperature superconductors levitated by the rotation of the drive-power magnets, the high-temperature superconductor you generated by the power coil installed in the vacuum container outer The cylindrical power generator may further include an attracting ring magnet that attracts the ring magnet through a support plate that supports a pipe in which the magnet at the center is inserted .

Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a schematic view showing the principle of a cylindrical power generator of the present invention, and FIG. 2 is a bottom view showing a high-temperature superconductor for levitation and an upper virtual magnetic field space of the cylindrical power generator.
In these figures, 1 is a cylindrical levitation magnet of a cylindrical power generator levitated by a high-temperature superconductor, 2 is a central magnet disposed in the central portion of the cylinder constituting the levitation magnet 1, 3 is a ring-shaped magnet arranged around the magnet 2 at the center, 4 is a pipe into which the magnet 2 at the center is inserted, 5 is a support plate for supporting the pipe 4, and 6 is a support plate for the ring-shaped magnet 3. An attracting ring-shaped magnet adsorbed via 5 is a circular levitation high-temperature superconductor disposed so as to face the levitation magnet 1. Here, the polarity of the magnet 2 at the center and the polarity of the ring-shaped magnet 3 are different. That is, the polarity of the magnet 2 at the center is the S-N pole from the top to the bottom in the vertical direction, and the polarity of the ring-shaped magnet 3 is the NS pole from the top to the bottom in the vertical direction.

With this configuration, a magnetic field of +0.45 T is generated below the central magnet 2 and −0.36 T is generated below the ring-shaped magnet 3. When these magnetic fields act on the circular levitation high-temperature superconductor 7, the cylindrical levitation magnet 1 can perform stable rotation about the central magnet 2.
FIG. 3 is a diagram showing measured values in the vertical direction of the cylindrical power generator of the present invention, and FIG. 4 is a diagram showing measured values in the horizontal direction of the cylindrical power generator of the present invention. In this actual measurement diagram, since the polarity is reversed, the relationship between the peaks and valleys is reversed from that in FIG.

  This point will be described in detail. Since the magnetic flux has a rule with an arrow from the north pole to the south pole, the actual magnetic field distribution of the rotor magnet is as shown in FIG. Since the circular high-temperature superconductor 7 for levitation has a characteristic capable of capturing the opposite pole at the same time, the opposite pole which is the magnetic force of the rotor is captured. Although it is a reverse pole in the actual measurement, it is related to Yamatani, but considering that the superconductor can capture the reverse pole at the same time, the potential energy relationship in the rotating field is maintained by virtual space with one pole inverted. Can be considered. This is illustrated in FIG.

FIG. 5 is a schematic view of a cylindrical power generator levitated by a high-temperature superconductor according to the first embodiment of the present invention.
In this figure, 11 is a vacuum vessel, 12 is a central magnet 12A arranged in the central portion of the lower part in the vacuum vessel 11, and a central magnet arranged so as to surround the central magnet 12A. 12A is a cylindrical levitation magnet composed of a ring-shaped magnet 12B having a polarity different from that of 12A, and 14 is a drive in which poles are alternately arranged in a line on the inner surface of the vacuum vessel 11 on the upper side of the cylindrical levitation magnet 12. A cylindrical body having a power generation magnet 13, a circular levitation high-temperature superconductor 15 disposed opposite to the lower portion of the cylindrical body 14, a driving coil 20 installed outside the vacuum vessel 11, and a vacuum A power generation coil 22 installed outside the container 11. After the cylindrical body 14 is disposed with a gap between the levitation high-temperature superconductor 15 before cooling, the levitation high-temperature superconductor 15 is cooled, the cylinder 14 is levitated, and the driving coil 20 After the drive / power generation magnet 13 is rotated and given a constant rotational force to the cylindrical body 14, the drive body / power generation magnet 13 is rotated by the inertia of the cylindrical body 14, and is installed outside the vacuum vessel 11 by the rotation of the drive / power generation magnet 13. The generated power generation coil 22 generates power. In addition, 16 is a cooling container, 17 is an introduction pipe for liquid nitrogen or liquid nitrogen vapor filled in the cooling container 16, 18 is a lead-out pipe for evaporated gas from the cooling container 16, 19 is a heat insulating layer, and 21 is for driving A power source 23 for supplying power to the coil 20 is a measuring device for the power generated from the power generating coil 22.

In this figure, the cylindrical body 14 and the levitation magnet 12 are completely fixed. Further, the driving / power-generating magnets 13 are uniformly arranged alternately in N and S on the upper side surface of the cylindrical body 14. The cylindrical body 14 and the drive / power generation magnet 13 are completely fixed.
Further, by aligning the central axis of the cylindrical body 14 and the circular levitation high-temperature superconductor 15 and reducing the diameter of the cylindrical body 14 to be substantially the same as or smaller than the diameter of the circular levitation high-temperature superconductor 15, It is desirable to configure so as to obtain a stable rotational motion by a pinning action.

Since it is configured in this manner, the magnetic axis of the center of the magnet 12A at the center is blocked by the surrounding magnetic poles and is restricted by point rotation. Therefore, more stable levitation rotation can be obtained than when levitation and rotation is performed only by the ring-shaped magnet 12B.
FIG. 6 is a partial schematic view of a cylindrical power generator levitated by a high-temperature superconductor according to a second embodiment of the present invention.

  In this figure, 31 is an upper disk, 32 is a drive / power generation magnet arranged on the upper disk 31, 33 is a drive coil arranged to face the drive / power generation magnet 32, and 34 is The power generation coil is disposed so as to face the drive / power generation magnet 32. Reference numeral 35 denotes a power source for supplying electric power to the driving coil 33, and reference numeral 36 denotes a measuring device for electric power generated by the power generating coil 34.

As described above, the drive / power generation magnet 32 may be arranged on the upper surface, and the drive coil 33 and the power generation coil 34 may be arranged corresponding to them.
In addition, it is good also considering the row | line | column of the magnet 32 for a drive and electric power generation as 2 rows (an upper surface and a side surface, or 2 rows in a side surface), one for driving and one for electric power generation. In this case, the drive coil 33 and the power generation coil 34 can be arranged so as to make a round along the cylindrical body.

In this figure, 41 is a vacuum vessel, 42 is a cylindrical body, 43 is a cylindrical outer frame, 44 is a cylindrical inner frame, 45 is a drive / power generation magnet, 46 is a power generation coil support plate, and 47 to 50 are power generation coil supports. A power generation coil 50 </ b> A periodically arranged on the plate 46 is a measuring device for the power generated by the power generation coils 47 to 50.

As described above, the power generation coils 47 to 50 can be arranged so as to make one turn along the cylindrical body 42.
Hereinafter, a specific example of a part of the cylindrical power generator levitated by the high-temperature superconductor of the present invention will be described.
Regarding the rotational speed of the cylindrical power generator levitated by the high-temperature superconductor of the present invention, the output voltage cycle was read as about 20 [msec] from the waveform of the oscilloscope. As a result, the frequency of the output voltage is [50 Hz].

Since 38 magnets are alternately arranged around the cylindrical body (rotating body) as N, S, N, S,..., 19 cycles of AC voltage are generated in one coil during one rotation of the rotating body. For this reason, the number of revolutions per second is 50/19 = 2.6 [rps], and the number of revolutions per minute is 2.6 × 60 = 158 [rpm].
FIG. 8 is an exploded view of a rotor of a cylindrical power generator levitated by a high-temperature superconductor showing a specific example of the present invention.

  As shown in this figure, the transparent acrylic cylindrical body 54 is φ70 × L70 × t3 mm (one), the pipe 51 arranged in the center is φ28 × L70 × t2 mm (one), and the support plate 52 of the pipe 51 is φ64 × φ28 × t2mm (4 sheets), laminated member 53 is φ60 × φ28 × t5mm (4 sheets), and drive / power generation magnet 55 is Nd (neodymium) magnet 10 × 5 × t1mm (0.18T, 38 sheets × 3) The ring magnet 56 for attracting is φ42 × φ31 × t4 mm (0.28T, attracting force 8 kg, one piece), and the ring-shaped magnet 57 is φ54 × φ37 × t14 mm (0.36T, one piece), arranged in the center. The magnet 58 in the center portion was φ22 × t10 mm (0.45 T, one piece), and was hardened with an epoxy adhesive so as to be φ22 leaving the lower surface. Here, the attracting ring magnet 56 attracts and fixes the ring magnet 57 via the support plate 52 supporting the pipe 51.

  The support plate 52 and the laminated member 53 are only penetrated by the pipe 51 disposed in the center, and are not bonded. The drive / power generation magnet 55 is alternately fixed to the support plate 52, the laminated member 53, and the support plate 52 with double-sided tape (double-sided adhesive tape) 59. The magnet is positioned on the transparent acrylic cylinder 54 via a double-sided tape (double-sided adhesive tape) 59. The N pole and the S pole are alternately fixed to the driving / power generation magnet 55, and further, the driving / power generation is performed by magnetic force thereon. The position of the magnet 55 is fixed [the gap between each magnet is adjusted with a ball 60 (one or two sheets of cardboard)]. The magnet of the transparent acrylic cylinder 54 The internal support plate 52, the laminated member 53, and the support plate 52 are fixed. An adsorption ring-shaped magnet 56 is sandwiched between the support plate 52, the laminated member 53, and the support plate 52, and the ring-shaped magnet 57 is fixed by the magnetic force of the adsorption ring-shaped magnet 56. After these are assembled, the magnet 58 at the center is inserted from the top of the pipe 51 arranged at the center. At this time, the relationship between the poles of the central magnet 58 and the ring-shaped magnet 57 must be reversed.

Due to this relationship, the magnet 58 in the central portion is fixed substantially the same by the magnetic force of the ring-shaped magnet 57. On the lower outer side of the transparent acrylic cylinder 54, wings for receiving artificial wind force with cello tape (registered trademark) are affixed at four locations (on the diagonal line). The total weight of the rotating body is 354 g. From the configuration of the magnet 58 and the ring-shaped magnet 57 in the central part, a magnetic force is created.
FIG. 9 is a configuration diagram of a cooling unit of a cylindrical power generator levitated by a high-temperature superconductor showing a specific example of the present invention, FIG. 9A is a side sectional view thereof, and FIG. 9B is a plan view thereof. It is.

As shown in FIG. 9, the cooling unit is high-temperature superconducting bulk body cooling portion 63 After the rectangular styrofoam 61 is divided into two liquid nitrogen runway 64, cut liquid nitrogen inlet 65 is bonded by e Po key sheet against adhesive material This was produced. A straw 66 was inserted into one corner of the open portion of the open portion for cooling the high-temperature superconducting bulk body 62, and a PTEE sheet (0.05 mm) 67 was fixed with Kapton tape (manufactured by Sumitomo 3M) 68. The vaporized nitrogen vapor was spontaneously released through the straw 66.

FIG. 10 is a configuration diagram of a power generating coil portion of a cylindrical power generator levitated by a high-temperature superconductor showing a specific example of the present invention, FIG. 10 (a) is a side view thereof, and FIG. 10 (b) is a plan view thereof. It is.
As shown in FIG. 10, the power generation coil section is composed of 300 windings (n = 50 × 6 ) of wrapping ETFE electric wires 74 [0.51 TA × 0.15 T (E)] on a soft iron rod 73 (φ6 × L60). A coil was attached to a transparent acrylic disc 71 (φ90 × φ190 × t5 mm, 15 mm, 30 mm, φ3 mm) with a binding band 75. Reference numeral 72 denotes a transparent acrylic cylindrical body (φ90 mm, H120 mm, t5 mm).

FIG. 11 is an overall assembly diagram of a cylindrical power generator levitated by a high-temperature superconductor showing a specific example of the present invention.
As shown in FIG. 11, a transparent acrylic cylindrical body 72 was inserted in which a 10 mm gap was placed on the cooling part in which the high-temperature superconducting bulk body 62 was inserted, and a rotor was placed thereon. The transparent acrylic disk 71 uses and holds three transparent acrylic cylinders 72. At this time, the rotor is placed at an equal position from each coil. Each coil is connected to the circuit (in this case, only one coil was connected to the oscilloscope). The wings {Cellotape (registered trademark)} attached to the rotor inserted into the transparent acrylic cylinder 72 are lifted and fixed so as to be exposed. Liquid nitrogen is introduced from the liquid nitrogen inlet 65 of the cooling unit, the high-temperature superconducting bulk body 62 is sufficiently cooled, and after the magnetic field of the rotor is captured, the rotor remains floating when the FRP inserted as a spacer is removed. To maintain.

When wind power is applied to the rotor wings using a straw or a silicon tube, the rotor rotates, and a current is generated in the surrounding coils by the rotor magnet to generate electricity. A two-day demonstration showed a uniform rotation.
Next, the magnetic top will be described.
The magnetic force generated in the lower part of the rotor can be explained as shown in FIG. The center magnet 58 is balanced and fixed with the magnetic force of the ring-shaped magnet 57 and the attracting ring-shaped magnet 56 only when the pipe 51 arranged at the center is provided. If there is no pipe 51 arranged in the center, the magnet 58 in the center part will end up with the ring-shaped magnet 57 and the attracting ring-shaped magnet 56.

  Since the superconductor captures the magnetic field regardless of the magnetic pole, it is clear that it captures the extreme magnetic field gradient as it is. Therefore, when viewed from the superconductor side, a magnetic field top axis as shown in the figure exists. As is well known, the magnetic field distribution always shows a mountain-like tendency from the “sandstone theory”. Then, since the magnetic field of the present invention having an extreme magnetic field gradient maintains an intensity distribution showing an extreme mountain shape, it can be regarded as a “magnetic top”. Up to now, the levitation rotation is a rotation as a “surface”, but in the present invention, it is reasonable to think that it acts as an “axis”.

Next, the floating small generator having the high-temperature superconducting bulk body of the present invention will be described.
FIG. 12 is a diagram showing the state of an experiment for improving the vertical magnetic flux density by laminating thin film magnets of the present invention, and FIG. 13 is a diagram showing the relationship between the number of magnets and the magnetic flux density.
In these figures, reference numeral 81 denotes a thin-film magnet, which is 5 mm wide × 10 mm long × ₁ mm thick t ₁ and has a surface magnetic flux density of 1800 G. 82 is a transparent acrylic plate (thickness 2 mm) on which a thin film magnet 81 is laminated, 83 is a magnetic flux sensor (XMXT-1442 type low temperature hall) for measuring the vertical magnetic flux density generated by the laminated thin film magnet 81. Element, Gauss meter LakeShore 421).

Incidentally, a protective FRP plate having a thickness of 0.84 mm is attached to the Hall element.
The same thin film magnets 81 were stacked, and the relationship between the number of magnets and the magnetic force was examined. Similarly, a transparent acrylic plate 82 was sandwiched between the magnetic flux sensor 83 and the magnet 81, and the relationship between the number of magnets and the magnetic force was examined.
Table 1 shows the relationship between the number of thin-film magnets and the magnetic flux density [unit: G (Gauss)] with and without such a transparent acrylic plate 82.

As is clear from the above, the value without the transparent acrylic plate 82 is larger than that with the transparent acrylic plate 82.
In these results, the increase in the vertical magnetic flux density was the most extreme up to about 4 magnets, and it gradually began to saturate from 4 to 10 magnets.

It is important to understand these relationships, especially when manufacturing a high-temperature superconducting bulk floating small generator, if a laminated magnet is inserted in advance, the weight of the rotor can be finely adjusted. means.
FIG. 13 shows the above experimental results. In FIG. 13, A indicates a value when there is no transparent acrylic plate, and B indicates a value when there is a transparent acrylic plate.

Although it is a well-known fact that the magnetic flux density does not double even if two identical thin-film magnets are stacked, in the experiment of the present invention, it increased to a saturation value according to the number of stacked layers. This is because the used magnet is a thin film, and the vertical magnetic flux density increases by stacking.
FIG. 14 is an exploded view of a rotor showing an embodiment of the present invention, and FIG. 15 is a model simulating a floating small generator having a high-temperature superconducting bulk body showing an embodiment of the present invention.

  In FIG. 14, reference numeral 91 denotes a rotor. The rotor 91 is supported by a pipe 92 disposed at the center, an upper member 93 disposed at the upper portion, a lower member 97 disposed at the lower portion, and the pipe 92. Support plates 94 and 95 and a thin-film magnet 96 disposed between the support plates 94. Further, 98 is a transparent acrylic cylindrical body covering the rotor 91, 99a is an upper member, 99b is a lower member, and the members 99a and 99b have a convex portion at the center, and the upper member 93 and the lower member 97 are provided. Has a concave portion at the center, and the rotator 91 is manually rotated by being supported by the upper support body 100 and the lower support body 101 using these uneven portions as a support base point.

On the other hand, a generator 110 that generates power by the rotation of the thin-film magnet 96 is disposed. In this generator 110, a wrapping ETFE electric wire 112 is disposed on a soft iron bar 111, and is attached to a fixed portion 114 by a binding band 113.
Incidentally, the pipe 92 is φ28 mm × L70 mm × thickness t is 2 mm, the support plate 94 is φ64 mm × φ28 mm × thickness t is 2 mm, the support plate 95 is φ60 mm × φ28 mm × thickness t is 5 mm, and the transparent acrylic cylindrical body 98 is φ70 mm. * L70 mm * Thickness t is 3 mm.

The measurement results are 0.325T for the two outer frame magnets and 17 inner magnets, 0.285T for the two outer frame magnets and two inner magnets, and 19 magnets directly. In the case of measurement, 0.485T, in the case of direct measurement of one magnet, 0.149T, 0 outer frame magnet and 1 inner magnet 0.043T.
These results are the same as the results of the relationship between the number of magnets and the magnetic flux density described above. The increase in vertical magnetic flux is the most extreme up to about 4 magnets, and it starts to saturate gradually from 4 to 10 magnets.

Understanding these relationships means that if a laminated magnet is inserted in advance when manufacturing a high-temperature superconducting bulk generator levitated small generator or motor, the weight of the rotor can be finely adjusted. I mean.
In the above embodiment, only the thin-film magnet for the power generation magnet has been described. Similarly, in the case of the levitation magnet, a plurality of thin-film magnets are stacked in the vertical direction to reduce the weight of the rotor. Subtle adjustment and adjustment of the magnetic force of the levitation magnet can be performed.

  Next, a total of 10 magnets in this rotating body model, 8 inside and 2 outside the rotor, were laminated to form 1 pole, and 2 poles, 8 poles, and 16 poles were configured and rotated manually. The output experiment of 1 coil in the case is shown. In the case of 2 poles, DC 0.2V, in the case of 8 poles, DC 0.2V, and in the case of 16 poles, DC 1.5 to 1.7V were shown. Naturally, in the case of 2 poles and 8 poles, a rectangular waveform was obtained, and in the case of 16 poles, a waveform close to an AC waveform was shown.

  Further, the present invention is not limited to the above-described embodiments, and various modifications can be made based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

The cylindrical power generator levitated by the high-temperature superconductor of the present invention can be used as a cylindrical power generator with a stable magnetic top.
