Description

Magnetic means of lodestone
The present invention relates to the new application of magnetite in the electrical equipment and electrical field.
Electrical equipment and electrical mainly is coil and unshakable in one's determination the composition, and the interaction in the magnetic field that produces by hot-wire coil produces power or electromotive force.Be applied to the so far normally magnetite of magnetite in electrical equipment and electrical set up magnetic field in air gap, or magnetite produces power with gravitation or repulsion mode in magnetic field, resembles to use stepping motor and the magnetic levitation technology.
Up to now last from 450 years, people constantly explore the magnetite perpetual machine, but the neither one success.Reason is a finding method in repulsion and gravisphere always.Two magnetites relatively move in a repulsion (or gravitation) scope, are a kind of conversion of similar potential energy.One of essential characteristic of magnetite is that homopolar-repulsion, heteropole are inhaled mutually.But only rely on repulsion and gravitation can not make the magnetite perpetual machine, just a fine hope.
The magnetic field usefulness that magnetic field that magnetite is set up and hot-wire coil are set up is just the same.It all is the energy form of expression.This magnetic field energy should obtain out and be applied.Magnetite magnetic field is inexhaustible rationally remaining unchanged for a long period of time under the service condition comparatively speaking.
The objective of the invention is to utilize magnetite to save energy, and from magnetite magnetic field, take out energy.
Reference book of the present invention is Electrical Engineer's handbook (second edition) China Machine Press; Mechanical engineer's handbook (second edition) China Machine Press; Permanent magnet mechanism, publishing house of the outstanding Beijing University of Technology of summer level field.
1. magnetite magnetic force
Fig. 1 is the device that magnetostatic stone J and moving magnetite D form, and magnetostatic stone J is a pipe, and the outside is the S utmost point, and the inboard is the N utmost point, and moving magnetite D is the cylindric of a band centre bore, and right-hand member is the N utmost point, and left end is the s utmost point.Pass a copper rod T in the centre bore, moving magnetite D can slide on copper rod T, will move magnetite D and copper rod T and place in the magnetostatic stone J pipe.Moving magnetite D is subjected to 3 kinds of power, F ABe called magnetite magnetic force, F BBe called repulsion, F CBe called gravitation.Direction as shown.Repulsion F BWith gravitation F CDirection and magnetic force F ADirection opposite, these three kinds of power regions are called magnetic force district, repulsion district, gravitation district respectively.F BBe repulsion owing to the N utmost point generation of the N utmost point that moves magnetite and magnetostatic stone, F CBe because the gravitation that the N utmost point of the S utmost point of moving magnetite and magnetostatic stone produces.Magnetite magnetic force FA the most meaningfully.
The definition of magnetite field axis
The N utmost point of magnetite and the line of the S utmost point are called the magnetite field axis.When magnetite was rectangle or shape such as cylindrical, its magnetite field axis was a straight line, and its direction dictates is a positive direction for the magnetic line of force direction from the N utmost point, is called for short the field axis direction, or field axis.
The definition of magnetic direction
From the magnetic line of force direction of the magnetic field N utmost point is positive direction, is called for short magnetic direction or magnetic field.
The definition of magnetite magnetic force
When moving the field axis direction vertical with place magnetostatic field direction (90 ° ± 45 °) of magnetite, moving magnetite is subjected to magnetic force, repulsion, three kinds of power of gravitation.The magnetic force that moving magnetite is subjected to is called for short magnetite magnetic force.The direction of magnetite magnetic force meets right-hand man's rule, and it is defined as the magnetostatic field direction and passes the left hand palm or the right hand palm palm of the hand, and four fingers are consistent with moving magnetite field axis direction side by side, and four refer to that directions (moving magnetite field axis direction) are the magnetite magnetic force direction.
Moving magnetite field axis direction and the said vertical scope that is meant of magnetostatic stone magnetic direction, promptly 90 ° ± 45 °.Magnetite magnetic force maximum is more little the closer to ± 45 ° of magnetite magnetic force in the time of 90 °, is 0 in the time of ± 45 °.Do not carry in the explanation from now on ± 45 ° the time, but contain ± 45 °.The electromagnetic force law of magnetite magnetic force and motor principle has similarity, in essence the same thing.With the DC motor is example, the magnetic field (magnetostatic field) that epitrochanterian winding energising produces on magnetic field (moving field) and the stator produces electromagnetic induction, the rotor winding is subjected to vertical with the stator field direction, simultaneously also vertical power with the electrified wire of rotor winding, and its direction meets left hand rule.Fig. 2 is the dc electromotor principle schematic diagram.By electric current I, electrified wire is subjected to downward power F in magnetostatic field N to rotor wire, and the magnetic field that B produces when being the rotor wire energising is by magnetostatic field N and the moving field B generation power F that interacts.
Fig. 3 is a magnetite magnetic force schematic diagram, is made up of magnetostatic stone J and moving magnetite D, and it is consistent with the moving field B direction of electrified wire generation among Fig. 2 that moving magnetite D produces moving field B.Moving magnetite is subjected to a downward power F, meets magnetite magnetic force direction regulation.The stressed F of motor rotor lead is consistent with the moving stressed F direction of magnetite D among Fig. 3 among Fig. 2 like this.Judge that thus the electromagnetic force that magnetite magnetic force and dc motor rotor are subjected to is the same in essence.All be that magnetostatic field and moving field interact to produce magnetic force, and the direction unanimity, just nominally one be called electromagnetic force, one is magnetite magnetic force, we can say that magnetite magnetic force is a kind of form of expression of electromagnetic force on magnetite.
Take out magnetite magnetic force from the magnetic force district as power source, repulsion and gravitation are adopted technical method or avoids, perhaps be used or reduce as far as possible.
The above-mentioned magnetite of persuading is relative with magnetostatic stone, and moving magnetite is fixed.Give magnetostatic stone guide rail, then the sound magnetite then changes.Same magnetic pole N also is relative with S, can exchange.Corresponding direction is corresponding conversion also.
2. magnet structure form
1) magnetostatic stone structure form
1. tubular structure
Version as shown in Figure 1.Moving magnetite rectilinear motion is stressed evenly in the straight line pipe.When carrying out curve or gyration, pipe then presents arc, spiral form perhaps occurs.Adopt the tubulose that a small gap is arranged in the practical application, the slit is used for moving magnetite support bar and transmits magnetic force.
2. symmetrical structure
Fig. 4 is the schematic diagram of symmetrical structure.J 1And J 2Be magnetostatic stone, pole orientation is relative.D is magnetite, is placed on J 1And J 2Between move, during rectilinear motion stressed evenly.When carrying out curve or gyration, magnetostatic stone is done camber or spirality etc.Symmetrical structure is the some of tubular structure, and applying flexible, leakage magnetic field are less relatively.
3. monomer structure
Fig. 5 is the schematic diagram of monomer structure.J is magnetostatic stone, and D is magnetite.Moving magnetite D is subjected to magnetite magnetic force, also is subjected to a moment M in addition.This moment M be since the N of magnetostatic stone J extremely to the gravitation of the S utmost point of moving magnetite D, and the moment that produces with the repulsion of the N utmost point of moving magnetite D.To consider the existence of this moment during design.Monomer structure also can be done camber, and is fan-shaped, spirality etc.Do not have this moment M in tubular structure and the symmetrical structure, reason is also to be subjected to moment M in tubular structure and the symmetrical structure, but is not only one group, but 2 groups of moment M, direction is opposite, cancels each other.
These 3 kinds of versions are selected a kind of form in actual use, or simultaneously more than 2 kinds.
2) moving magnet structure form and motion mode
Moving magnet structure form and magnetostatic stone structure form are closely related, cooperatively interact, and moving magnetite is made up of one or more.
Moving magnetite motion mode, shown in Figure 1 is guide rail slide block form.In straight line or curvilinear motion, use.When motion is rotation mode, adopt the guide rail slide block, also can adopt the mode of pivoting.The centre of moment of motion mode and generation magnetic force vows that the selection of warp has much relations.
3. magnetite electromagnet apparatus
The present invention is the application of magnetite in electrical equipment.Electromagnet in the past reaches all to be made up of coil and armature the operation part of its relay of doing for core, contactor, and behind the coil electricity, armature motion drives the contact action to assigned position.Keeping the post exercise attracting state must be always to coil electricity, and this device solves is kept when operation task without electric energy.
This device is made up of solenoid and magnetite, and magnetostatic field is formed by the magnetic field of solenoid generation and by magnetic field two parts that magnetostatic stone produces.Replace original armature by moving magnetite, the field axis direction of moving magnetite is vertical with the magnetostatic field direction.Fig. 6 is the principle schematic (vertical view) of this device.By magnetostatic stone J 1And J 2Electromagnetism line chart X 1And X 2Form magnetostatic field.Moving magnetite D is at the magnetostatic field intermediary movements.Fig. 7 is the side-looking expanded view of Fig. 6.This figure only represents magnetostatic stone J 2, solenoid X 1, moving magnetite D, F A, F B, F CThe magnetic force district, repulsion district, the gravitation district that represent magnetic force, repulsion, gravitation and representative thereof that the interaction of magnetostatic stone and moving magnetite produces respectively.H 1And H 2Be spring.Moving magnetite D is subjected to F in initial condition BRepulsion and spring H 1Pressure and stablize regulation solenoid X 1And X 2The static magnetic field strength that produces is greater than magnetostatic stone J 1And J 2The static magnetic field strength that produces.As shown, regulation solenoid X 1And X 2Gravitation district and magnetostatic stone J 1And J 2The gravitation zone position identical, solenoid X 1And X 2The magnetic force district to all cover magnetostatic stone J 1And J 2The magnetic force district, cover magnetostatic stone J simultaneously 1And J 2The part in repulsion district.During startup, solenoid X 1And X 2Energising produces and magnetostatic stone J 1And J 2The magnetic field of equidirectional.Produce magnetic force, moving magnetite overcomes magnetostatic stone J under the effect of this magnetic force 1And J 2Repulsion enter the magnetic force district of magnetostatic stone, enter into the gravitation district again, turn-off current then, moving magnetite D is at magnetostatic stone J 1And J 2Magnetic force and the gravitation acting in conjunction under, be stabilized in the point of interface in magnetic force district and gravitation district, spring H 2Anti-stop magnetite D motional inertia is excessive and be provided with.Moving like this magnetite D is stabilized in this point under solenoid no power state.When closing, solenoid is passed to electric current in the other direction.Because the static magnetic field strength of solenoid is greater than the magnetic field intensity of magnetostatic stone, moving magnetite under the backing field effect that produces, is got back to initial position again when solenoid is switched on, and then turn-off current.Moving magnetite is kept initial condition again.Electric current of make-and-break is carried out by the program of the folding of the contact of switch or electromagnet.This device has only been accomplished to keep and move not electricity consumption in the moment electricity consumption that starts and close.This device all is used to magnetic force, repulsion, gravitation.
Be reduced volume, also can make the form of the frequent use of electromagnet relay contactor.For example solenoid is done circularly, had only one, magnetostatic stone is made tubular type, also has only one, and 2 covers are integral, and moving magnetite is at intermediary movements.
This device can be used on electromagnet, on the products such as contactor, relay, reaches energy-conservation noiseless operation.
4. the magnetic line of force, stress curve, rate of change of magnetic
1) magnetic line of force.
The magnetic line of force is the traverse line of Distribution of Magnetic Field, and any point tangential direction is exactly the direction in this magnetic field on the magnetic line of force, and the density of the magnetic line of force is proportional to magnetic field intensity.The magnetic line of force from a magnetic source sends can not intersect, and every adjacent two magnetic lines of force all are (being homopolar-repulsion) of repelling mutually, so the magnetic line of force is dispersed.The magnetic line of force sends and gets back to the S utmost point from the N utmost point, and the material that permeability is high can make the magnetic line of force concentrate operation easily.Fig. 8 is that magnetic line of force different phase is subjected to the different schematic diagram of force direction.The magnetic force F that positive direction is arranged in 90 ° ± 45 ° scopes in field axis angular separation of the magnetic line of force of the N utmost point of magnetostatic field J and moving magnetite D A, when angle was 90 ° ± 45 °, magnetic force was 0.When angle during, then produce repulsion F greater than 90 ° ± 45 ° BWith gravitation F CF A, F B, F CIt varies in size at difference.
2) stress curve.
The test of stress curve is adopted on magnetostatic stone of monomer and the copper rod has the stressed size of the magnetite with holes of slip to carry out.
1. stress curve 1
Fig. 9 is that its directions X of magnetostatic stone J (referring to paper) of making progress of a N utmost point is close with Y direction size, records stress curve QX at directions X and Y direction 1And QY 1, these two curve shapes are close, are being positive direction F more than 0 o'clock A, be repulsion F below 0 o'clock BWith gravitation F C
2. stress curve 2
Figure 10 is the stress curve QX that records on the N of magnetostatic stone J utmost point pole-face 2And QY 2, N utmost point pole-face directions X is than long several times of Y direction.Article two, the width of curve is all mutually far short of what is expected with amplitude.Curve QX 2Slightly cave in the centre, curve QY 2The centre is the peak.
3. stress curve 3
Figure 11 is the stress curve QX that records on the N of magnetostatic stone J utmost point pole-face 3And QY 3, the length of N utmost point pole-face directions X is far longer than Y direction length.QY 3Become very narrow very steep, the curve that amplitude is very big.QX 3Become two ends slightly peak value part broad in the middle is stressed and approach 0.Curve QX 3Be called recessed stress curve.When the magnetostatic road of design, to avoid occurring.When wanting to utilize strong stress curve, can utilize QY 3Curve.
4. the variation of stress curve direction
If the circular-arc sector of directions X among Figure 11.Also there is recessed stress curve.The stress curve that approximate QX3 is arranged at fan-shaped magnetite two ends.Part stress curve broad in the middle almost approaches 0.And curve QY 3Peak dot very high.When becoming the ring-type magnetite when further the two ends of fan-shaped magnetite being extended, QX then 3The stressed peak dot at two ends all disappears QX in the stress curve 3Curve becomes 0 line.In the Y direction then is high peak dot everywhere.When a little covering of the fan progressively becomes annulus, circle ring center's circle line no longer stressed (directions X does not stress) and all focus on Y direction (radially).This is the extreme case of recessed stress curve.
Recessed stress curve also appears in magnetic circuit that 5. a plurality of magnetites are formed easily
Monomer, symmetry, the tubular structure form, consistent as long as same magnetic pole pole-face points to, and also distance is little, forms a magnetic field in blocks easily and also occurs recessed stress curve easily.Even the mid portion of recessed stress curve is less than 0, it is stressed also to reduce greatly.Avoid this situation to occur, the length of magnetite and width are adapted, the distance between magnetite is also suitable.
3) rate of change of magnetic
1. two above magnetite magnetic fields influences each other
Can not intersect from the magnetic line of force of a magnetite magnetic source, but the magnetic line of force that sends from two magnetite magnetic sources can intersect.The magnetic line of force direction of its intersection point be original two magnetic lines of force in this vector and direction.The magnetite magnetic force that positive direction is just arranged when having only this vector and direction and moving magnetite axis direction angle in 90 ° ± 45 °.If many magnetic line of force vectors and direction are always a direction and continuously then easily produce recessed stress curve.
At non-magnetic confining field, promptly open magnetic field because the magnetic line of force is what disperse, all influences each other between all magnetites in a zone.
2. rate of change of magnetic
In the law of electromagnetic induction E = dφm dt , Promptly during the magnetic flux change by a closed-loop path, produce electromotive force, this electromotive force E and the magnetic flux ф m that passes the loop negative value of rate over time are directly proportional.The variation of this magnetic flux is the variation in magnetic field just, just the rate of change in magnetic field.The variation in magnetic field comprises the variation of magnetic direction and the variation of amplitude.In its tangible electromagnetic force law rate of change of magnetic must be arranged.Do not have the variation in magnetic field equally, then be prone to recessed stress curve, even not stressed.Rate of change of magnetic is the same in itself with recessed stress curve, two kinds of negative the other side's the form of expression.So a complete magnetite magnetic circuit must have rate of change of magnetic.
4) selection of magnetic force moment three elements
The application point of power, the arrow warp of power, the centre of moment of power constitutes the moment three elements.The application point of power is exactly moving magnetite in this device, and promptly moving magnetite is subjected to magneticaction.The selection result of vowing the warp and the centre of moment is the magnetic force maximum for magnetite is subjected to.For example, moving magnetite is on the N utmost point pole-face that makes progress of the magnetostatic stone of annulus, and promptly stress action spot is on the annulus, and the centre of moment is selected the center of circle of annulus, vows through being the radius of annulus, and then moving magnetite does not stress.Kindred circumstances only changes the centre of moment, if the centre of moment also is chosen on the annulus, then moving magnetite is subjected to very big power.So during design, divide the tracks of considering moving magnetite earlier, magnetostatic stone rate of change of magnetic reaches the centre of moment and arrow through selecting.
5) by three necessary conditions of a plurality of magnetite component movement devices
1. move the field axis direction vertical with the magnetostatic field direction (90 ° ± 45 °) of magnetite
2. enough rate of change of magnetic prevent that recessed stress curve from occurring
3. avoid or reduce repulsion and gravitation, avoid or reduce 90 ° ± 45 ° beyond the opposite direction magnetic force
5. magnetite motor
The application of magnetite on motor.The brushless dc motor, the magneto stepping motor, absence of commutator autosynchronous motors etc. all have magnetite on the rotor, winding is arranged on the stator.Rotor rotation is because the repulsion between the magnetic field of rotor magnetite and stator winding generation or gravitation effect.The magnetic direction of magnetite is towards air gap, and the magnetic direction that produces with winding becomes 180 ° or 0 °.
This machine and brushless DC motor configurations are close, and magnetite is all arranged on the rotor, and winding is arranged on the stator, have rotor position detector.Difference has 2.One is, brushless DC motor rotor magnetite magnetic direction becomes 180 ° or 0 ° towards air gap with the winding magnetic direction.The field axis direction of the moving magnetite on this machine rotor is perpendicular to the magnetic direction of stator winding.Another is, has only winding on the brushless DC motor stator, this machine is that winding is arranged on the stator, magnetostatic stone is also arranged, the core shoe of winding and magnetostatic stone are separately and seamless link, the rotation of rotor is to drive by the magnetic force of moving magnetite magnetic field with the magnetostatic field generation of stator, and epitrochanterian position detector passes to the part of accepting on the stator with position signalling.After signal processing, control the energising moment and time length of winding.Figure 12 is a magnetite motor principle schematic diagram (vertical view), and stator is by magnetostatic stone J 1, J 2, J 3, solenoid X 1And X 2Form.Solenoid is alternate with magnetostatic stone uniform.The core shoe of solenoid and magnetostatic stone are close to and do not have the gap.Surround circular ring type by some magnetostatic stones and solenoid.Rotor is by moving magnetite D, rotating shaft O, and radial link L forms.Moving magnetite D has a plurality of even distributions.Moving magnetite D enters magnetostatic stone J 1Magnetic field N after, driven by magnetic force and move forward, near solenoid X 1The time, solenoid X 1Energising, at this moment magnetostatic stone J 1, solenoid X 1, magnetostatic stone J 2Magnetic field join together, the magnetic direction unanimity, moving magnetite D under magneticaction by solenoid X 1, enter magnetostatic stone J 2Magnetic field after cutoff solenoid X 1Electric current, when moving magnetite D near solenoid X 2The time, to solenoid X 2Energising, magnetostatic stone J at this moment 2, solenoid X 2, magnetostatic stone J 3Magnetic field join together.The magnetic direction unanimity.Owing to solenoid X1 this moment, no power, its iron core is with magnetostatic stone J 1, J 2Magnetic field separate.Moving magnetite D is under magneticaction, by solenoid X 2Enter magnetostatic stone J 3Behind the magnetic field, cutoff solenoid X again 2Electric current.When the coil no power, its core portion is passed through the magnetic line of force, but opposite with adjacent magnetostatic stone magnetic direction.So disconnected adjacent magnetostatic stone magnetic field, stressed in this backing field, repulsion and gravitation just, coil one switch on then that repulsion and gravitation disappear.And the like, the magnetic force district becomes a rotating magnetic field that constantly reconfigures.In moving the suffered power of magnetite, repulsion and gravitation are left out all the time.Thereby repulsion district and gravitation district have been avoided.What the energising of solenoid constantly and conduction time, length was controlled signal processing afterwards by rotor position detector.The version of magnetostatic stone can adopt forms such as tubulose, symmetry shape, monomer.Solenoid is made corresponding structure and is changed.
The pole orientation of magnetostatic stone and solenoid be the top of paper and below.The situation of the top N utmost point of bottom surface below only has been described.The S utmost point below also can be provided with moving magnetite in fact.But moving up and down magnetite polarity is opposite, but direction of motion unanimity.Utilize 2 magnetic pole efficient to improve.In like manner this axially (up and down) magnetostatic field is changed over radially (about) magnetostatic field too, use 2 magnetic poles.
Change the size of electrical current, direction, can have speed governing and brake function at conduction time.
When the effective magnetic field area of the generation of the solenoid on the stator equals the effective magnetic field area of magnetostatic stone, import 100% power substantially, 200% power output will be arranged.During actual fabrication, after adopting various technical measures with the effective magnetic field area of solenoid little to magnetostatic stone effective magnetic field area 1/10th or littler.For example magnetostatic stone is made thick middle,, reduce the input power of solenoid with measure such as solenoid contact portion attenuation.
Brushless DC motor, the magneto stepping motor, all have the motor of magnetite absence of commutator autosynchronous motors etc. on rotor, all can the field axis direction of epitrochanterian moving magnetite is vertical with the magnetic direction of stator, can raise the efficiency or simplified structure.
This machine can be made power-equipment and use, and also can form generating set.
6. the magnetite iron core replaces magnetostatic road device in the adjacent magnetostatic stone gap
The same with the motor of magnetite described in 5, only solenoid is replaced as little magnetite and little iron core.Illustrating that with Figure 12 little magnetite is the same with little core dimensions, is that magnetostatic stone gap size is the same with solenoid among the figure.Its effect is when little magnetite is in the gap, is equivalent to the solenoid "on" position, when little iron core is in the gap, is equivalent to the solenoid no power.The field axis direction of moving magnetite is vertical with the magnetostatic field direction.When moving magnetite when the adjacent magnetostatic stone gap, little magnetite is pushed in the gap, little magnetite magnetic direction is consistent with adjacent magnetostatic field direction.So little magnetite joins together adjacent magnetostatic stone magnetic field.Moving magnetite when too small magnetite magnetic field enters next magnetostatic stone magnetic field after, little magnetite is withdrawed from from the gap.Simultaneously little iron core is brought into the gap, so little iron core is spaced apart adjacent magnetostatic stone magnetic field again.And the like, the magnetic force district also becomes a rotating magnetic field that constantly reconfigures.Moving magnetite is moved by magnetic force constantly.This device has been avoided repulsion and gravitation.Little magnetite and little iron core enter the gap to be undertaken by a cover position synchronous linkage.For example, cam gear and the spring that is connected with rotating shaft by gear finished.Magnetostatic field also can reduce the size of little magnetite and little iron core through after the technical finesse as far as possible in this device.Reduce the power that makes its turnover gap.This device is except that not electricity consumption, and other are the same with the magnetite motor.But need initial tripping force.
7. the adjacent magnetostatic stone magnetostatic road device of exhausted magnetic material interval
Here refer to that insulating material only sees that at present superconductor material has diamagnetism, superconductor can stop a large amount of magnetic lines of force to pass through, just as electrical insulating material impedance electric current by.Adopt the version of Figure 12, solenoid is changed over exhausted magnetic material, make the field axis direction of magnetite vertical with the magnetostatic field direction, at this moment magnetostatic field becomes magnetic field positive pulse one by one, between magnetic field pulse, then do not allow the magnetic line of force pass through owing to cut off the magnetic material, then moving magnetite field axis direction and magnetostatic field direction have only 90 ° ± 45 ° with the interior magnetic line of force, have avoided other angle magnetic lines of force, have reduced repulsion and gravitation.
8. the magnetostatic road of magnetite magnetic confining field device
Figure 13 is the schematic diagram of magnetic confining field.Guide and retrain magnetic line of force direction with magnetite itself.The arrow direction is the magnetite internal magnetic field direction of each piece among the figure.Between every adjacent little magnetite small gap is arranged, in magnetic field of the inner formation of tubular body, and the tubular body external magnetic field is leaked seldom.Overwhelming majority magnetic field concentration is in the space that tubular body enclosed.When every block among Figure 13 little magnetite is resolved into more little magnetite again, the angle of every adjacent little magnetite internal magnetic field direction becomes littler.Its magnetic field becomes more even, leaks still less.Moving magnetite D is two.One one two moving magnetite polarity are opposite, are subjected to force direction identical near the magnetic field S utmost point near the magnetic field N utmost point, and field axis is vertical with magnetostatic field.Slit by magnetostatic road links to each other with axle O by connecting rod.Be combined into an annulus or curve shape by several this single tubulose magnetic confining fields, leave the gap between every adjacent magnetic confining field, handle, reduce power in the other direction by adjacent magnetostatic stone interstitial treatment technology.
This device can also be brought use to the effect of the described solenoid of magnetite motor.Here solenoid is made by 2 and surrounded a tubulose, polarity is the same with magnetic confining field.Solenoid is placed the gap location of adjacent magnetic confining field, and the N utmost point of solenoid is consistent with the N utmost point and the S extreme direction of magnetic confining field with the S utmost point.Solenoid plays adjacent 2 effects that magnetic confining field couples together or disconnects.All properties with magnetite motor.
9. magnetostatic road device is arranged in dislocation around the moving magnetite tracks
Figure 14 is the schematic diagram of this version.Magnetostatic stone J 1～J 6On a ring ring, arrange.Figure 15 is the radial development figure of Figure 14.Magnetostatic stone J 1, J 2, J 3On torus space, arrange as shown in figure 15 successively.Its magnetic direction all points to circle ring center's line, and moving magnetite D moves on circle ring center's line.J 4, J 5, J 6With J 1, J 2, J 3Arrange the same.And the like, surround the whole magnetostatic road of an approximate helix form by some magnetostatic stones.Moving magnetite D field axis direction is vertical with magnetostatic field.Have than the large space distance between the magnetostatic stone of same position on the circular ring type magnetostatic field.J for example 1And J 4, the position is identical, but segment distance is arranged.Rate of change of magnetic has so just been arranged.Adjacent magnetostatic stone connection reduces power in the other direction through the technical finesse of adjacent magnetostatic stone interstitial treatment.The magnetostatic field of adjacent magnetostatic stone can have small magnetic field overlapping.But still have certain angle.
This dislocation arrangement situation is varied, as long as there is certain intervals similar position, each adjacent magnetostatic field direction difference does not produce recessed stress curve.
10. adjacent magnetostatic stone interstitial treatment technology
At adjacent magnetostatic stone gap location repulsion and gravitation are arranged generally speaking.Be the opposite direction power of magnetic force.Sometimes also exist because the opposite direction magnetic force that the variation of magnetic line of force direction produces.
1) adopts magnetostatic stone thick middle, the form of thin edge
As shown in figure 16.The shape of magnetostatic stone J reduces repulsion and gravitation.
2) guide and retrain magnetic line of force direction with magnetite itself
