Specific embodiment
Due to producing repulsive force when the PG thin plate with the diamagnetic substance for bearing magnetic susceptibility is placed on magnetic field space, thus
The maglev technology of PG thin plate is known technology.
The running gear of the present invention has：Magnet, forms the magnetic field for making PG sheet suspended；PG thin plate, on magnetic field
Suspend and move.
The material with negative magnetic susceptibility has the nonferrous metal such as copper, lead, bismuth, silver, and graphite, diamond, PG etc. are nonmetallic.
Now, repulsive force F is expressed as：
F=(χ/μ0)·V·B·dB/dz (1)
Wherein, χ：Magnetic susceptibility
μ0：The permeability (H/m) of vacuum
V：Volume (m3)
B：Magnetic flux density (T)
dB/dz：The gradient (T/m) of the vertical direction of magnetic flux density B
In above formula, though by N pole, S extremely in the magnetic flux density of either one be just defined as, the product of B and dB/dz is B
DB/dz is also negative.Due to magnetic susceptibility be negative, so repulsive force F is extremely unrelated with N pole, S and be just, become repulsive force.In this way,
It is characterized in that the repulsive force for diamagnetic substance does not rely on the polarity of magnet.
According to above formula, the size of repulsive force F is directly proportional to magnetic susceptibility χ, and therefore, the absolute value of magnetic susceptibility χ is bigger, then repel
Power F is bigger.
But, for it at normal temperatures there is the magnetic susceptibility of the material for bearing magnetic susceptibility, the copper of such as nonferrous metal
For 1.0 (× 10-5), lead is 1.8 (× 10-5), silver is 2.6 (× 10-5), bismuth is 16.6 (× 10-5).In nonmetallic, graphite
For 1.6 (× 10-5), diamond is 2.1 (× 10-5), PG is 40.9 (× 10-5).Understand the exhausted of the particularly magnetic susceptibility of PG
It is maximum to value in these diamagnetic substances.And, the density of PG is little, is 2.2g/cm3, it is suitable for magnetic suspension.
Hydrocarbon is typically decomposed and carries out chemical vapor deposition (CVD) and obtain in the vacuum drying oven of high temperature by PG
's.The density of PG is close to theoretical value, the high and stable chemical nature of purity, and mechanical strength and heat endurance are more excellent than common graphite
Different.PG forms Rotating fields in the thickness direction of chemical vapor deposition, with very strong anisotropy.PG be characterized in that with accumulation
Layer the vertical direction in face on, the absolute value of magnetic susceptibility χ is big.
Generally in the PG thickness that can have been bought on the market in 1mm or so to number mm or so, processing easily, is therefore also most suitable
Close the diamagnetic substance for using in the present invention.
It is preferred that the thickness of the PG thin plate 5 for using in the present invention is 0.3～1.5mm.
In order that it is that 0.5mm or so is following that magnetic repulsion effectively acts on the thickness of PG, PG, thickness for 0.5mm with
In the case of upper, weight simply increased, and shortens maglev distance.And, according to manufacture method, the price of PG
For high price, which increases proportionally with thickness.Therefore, thickness is preferably in below 1.5mm.
On the other hand, it is difficult to be processed into below 0.3mm, and intensity decreases it is easily broken.And, PG thin plate 5 is walked
When resistance be substantially air drag, it is believed that resistance is hardly dependent on thickness, and increases in proportion to surface area.
On the other hand, as the kinetic energy of PG thin plate 5 is that thickness is directly proportional to weight, therefore the appropriate PG thin plate 5 for thickening is easily against sky
Atmidometer and walk, and be not readily susceptible to the impact of beam wind etc..
According to above explanation, these key elements are considered, preferably make thickness for more than 0.3mm and below 1.5mm.
The flat shape of the PG thin plate used in the present invention can be following shape.
If the width of magnet is w, the columns of magnet is m, being shaped as in top view：
The circle of a diameter of more than 1.5w and (m-2.7) below w,
While for more than 1.5w and the square of (m-2.7) below w,
Minor face is more than 1.5w and the rectangle of (m-2.7) below w,
Polygon of a diameter of more than 1.5w of circumscribed circle and (m-2.7) below w etc..
By using described shape, the PG thin plate of size, the ring-type for changing track in outlet and loop can be made continuous
Walking becomes stable.
In the apparatus of the present, as constitute magnet row permanent magnet, using field orientation thickness direction length
The neodium magnet of cube shape.In the magnet that can have been bought now, the maximum magnetic energy product of neodium magnet is maximum, even small-sized magnet
Also very strong magnetic flux distribution can be obtained around which.
And, the magnet of rectangular shape can be manufactured by following method：By the formed body of big bulk by suitable
In improve degree of orientation transverse magnetic pressing shaping after, be sintered, be heat-treated, then using peripheral edge, inner circumferential sword or
Multi-line cutting machine is cut off.High performance magnet is produced well thereby, it is possible to yield rate.Consider from this point, with use
The magnet of the complicated shapes such as arc-shaped is compared, not only characteristically highly beneficial, and also non-from for the viewpoint of economy
Chang Youli.
If neodium magnet big with high performance maximum magnetic energy product for the PG with the big negative magnetic susceptibility of absolute value is carried out group
Close, then can magnetic suspension and frictional force be the walking of zero ground.
Then, the characteristic and shape below for the neodium magnet for being used is described in detail.
According to formula (1), the magnetic suspension force of diamagnetic substance is independent of the direction of magnetic pole, magnetic flux density B and the magnetic with magnet
The product of gradient dB/dz of the vertical direction of flux density is directly proportional.
Therefore, the big neodium magnet of the neodium magnet for being used preferably at most magnetic energy product.And, by by adjacent magnet configuration
Become magnetic pole toward each other conversely, the product i.e. big region of repulsive force greatly of B and dB/dz can be arranged on magnet surface.
At present, it is also not impossible that neodium magnet of the maximum magnetic energy product more than 45MGOe or 50MGOe is bought.
But, the neodium magnet of the rectangular shape used in the present invention can also be for example 35MGOe using maximum magnetic energy product
The neodium magnet of level.
Confirm：Magnet for example by maximum magnetic energy product for 35MGOe level makes thickness 1.5mm, and left in thickness 1mm
On the steel plate that right soft magnetic material is made more than three row of arrangement, then the surface magnetic flux density of 370mT can be obtained, can be made
The sheet suspended height in about 0.5mm of PG of thickness 0.5mm.As fruit suspension 0.5mm, then stably can suspend walking.Therefore,
Also include the situation for the magnet of 35MGOe level using maximum magnetic energy product in the present invention.
According to above-mentioned record, the thickness of neodium magnet is more than 1.5mm.And, make PG thin to increase repulsive force
The walking of plate is stable, and preferably the thickness of magnet is more than 2mm.On the other hand, there is the more big then magnetic flux density of magnet thickness also more
Big trend, but the price of the more big then magnet of magnet thickness is also higher, also further increases magnetic adsorbability, is also serving as magnetic
Arrangement operation on the pedestal that yoke plays a role becomes difficult, it is therefore preferable that the thickness of magnet is below 6mm.
There is the big trend of the more narrow then surface magnetic flux density of width of neodium magnet, but when magnet width is narrow, overall width
Degree also narrows, the degraded appearance of running gear.Therefore, preferably minimum more than the 3mm of the width of magnet.
On the other hand, the more wide then price of the width of magnet is higher.And, there is the trend of surface magnetic flux density step-down.Separately
Outward, increase to play the characteristic of magnet to greatest extent and increasing the thickness of the yoke required for magnetic flux density, then device is whole
The weight of body increases.In addition, yoke be base material thickness bigger, then cut-out or bending machining be more difficult to, particularly make width
Two lateral bends in direction simultaneously inwardly roll oblique processing or two ends and reverse processing and be more difficult to.And, the width of magnet is bigger, then magnet
Magnetic adsorbability to pedestal is also bigger, and arrangement operation is also more difficult.It is therefore preferable that the width of magnet is with 12mm or so as the upper limit.
The width of more preferably magnet is more than 4mm and below 10mm.
According to following reasons, the preferably length of neodium magnet in the range of 1 times to 4 times of the width of magnet, more preferably
1.5 times of width to 3 times.
In the direction of the width, the polar alignment of magnet surface in the opposite direction, therefore each other magnetic suck and stablize.But,
Especially for the straight line moving region beyond the cyclotron turnover region of the PG thin plate eliminated near long side direction two ends, due to
The magnet of identical polar is arranged in long side direction, therefore mutually exclusive.Even so, due to being magnetically attached to base material, so
Even if not using binding agent, also being capable of closely sealed fixation each other using the frictional force between base material.In order to effectively utilize
More than 1 times of the minimum magnet width of the length of such frictional force, preferably magnet.More preferably more than 1.5 times.
On the other hand, the length of magnet is longer, then, when arranging magnet on the base component of bending, magnet surface is formed
Curved surface easier deviate smooth flexure plane.Accordingly, there exist the trend that the walking of PG thin plate also has some setbacks.In addition, to pedestal
The magnetic adsorbability of material can also increase, it is difficult to carry out arrangement operation.
Further, the flexibility particularly near the long side direction both ends of pedestal 2 increases and the little portion of radius of curvature r
Position, if increasing the length of magnet, the gap below the length direction central portion of each magnet between pedestal increases, and exists
Pedestal is used as the trend that also reduces of effect of yoke.
Consideration factors above, preferred length are less than 4 times of width.More preferably less than 3 times.
Particularly when length is for 2 times of width, the magnet in the convolution region due to increased the PG thin plate near two ends
The configuration free degree, is therefore selected as optimum size.
In the apparatus of the present, in the straight walking area in addition to the inversion region of the PG thin plate 5 near both ends
Domain, in order to swimmingly walk, needs to make the distribution of the direction of travel i.e. magnetic flux density of long side direction constant.Accordingly, it would be desirable to
Magnetic identical magnet in long side direction arrayed surface.And, keep stable to be difficult to mobile in width, and
In order to improve the magnetic suspension force of PG further, need to make magnetic flux distribution form peak and valley.Accordingly, it would be desirable to width with
The different mode of magnetic arranges magnet each other.
On the other hand, the inversion region of the PG thin plate 5 near the both ends of long side direction, moving direction is mainly and length
The rectangular width of edge direction, it is not necessary to straight travel region identical magnet configuration.
But, it is allowed to suspend to increase to the repulsive force of PG thin plate 5, the polarity of the magnet for needing to make adjacent is each other not
With.In addition, under such a configuration, magnetic suck each other between magnet, therefore, on pedestal, also easily arrange magnet.
When the magnet configuration of the inversion region of PG thin plate 5 at long side direction two ends is determined, it is considered to which factors above configures magnetic
Iron, can carry out various selections.
In the apparatus of the present, using in long side direction towards the raised forniciform pedestal in downside and using making pedestal
Two ends reverse structure.Therefore, PG thin plate 5 is close to the two ends of pedestal and when speed reduces, direction of travel is changed under becoming
The width on slope.Now, in order that the velocity composition of width is zero, magnet row side is provided with side wall.
Side wall is arranged at PG thin plate 5 and changes nyctitropic region.And, all-round more preferably including the two ends including long side direction
Side wall is set, it is possible thereby to increase the shape of PG thin plate 5 described later, the free degree of size.
As PG thin plate 5 is from the suspension distance about 1mm of magnet surface, it is therefore preferable that height of the side wall apart from magnet surface
Degree be than the suspension apart from big about more than 2mm.
In addition, inwardly rolling tiltedly in the neodium magnet 3 arranged using the magnet made positioned at magnet column width direction two ends described later
Method in the case of, the distance on the bottom surface of PG and the surface of magnet is close to.Therefore, if side wall apart from magnet surface height
1mm or so is just enough.
Side wall for example can be using plastics such as propylene.
Then, the present invention is described in detail using accompanying drawing.
(a) of Fig. 1 is the top view of that represents assembly of the invention, and (b) is the width shown in the L-L ' line of (a)
The profile of direction central vertical wire cutting, (c) is front view.Wherein, in order to easy to understand, section is illustrate only in (b)
Local.In addition, in (c), configuring the side wall in magnet side and not drawing.In addition, not drawing for recognizing magnet yet
The line of row.
As illustrated, in left part it can be seen that the surface of the magnet row of inboard, in right part it can be seen that nearby side
The side of magnet row and the bottom surface of pedestal 2.
As shown in (a) of Fig. 1, the running gear 1 of the present invention is being made up of the soft magnetic steel plate for being processed as strip
The five row magnet row 4 of surface alignment of pedestal 2, the magnet row 4 are arranged with the neodium magnet of the rectangular shape for being oriented in thickness direction
3.In the example depicted in figure 1, in addition to the magnet at long side direction two ends, the magnetic all same of the magnet surface of each row, and
And polarity in the adjacent magnet surface of width is arranged in each other for rightabout.
As long as in this way, the neodium magnet 3 using undersized rectangular shape, it becomes possible to even if be readily derived pedestal 2 being
Curved surface also can be along the magnet row 4 of the curved surface.
As shown in (b) of Fig. 1, pedestal 2 is formed as in long side direction bending raised downward.And, as (c) institute
Show, in the structure that reverses in long side direction.Reverse and be：In the left side of long side direction, the nearby side of paper becomes descending, on the right side
In contrast, the inboard of paper becomes descending for side.
(a), (b), (c) of Fig. 2 respectively schematically represents A-A ' line along Fig. 1, B-B ' line, the section of C-C ' line
Figure.That is, (a) represents the section of the drawing left end of long side direction, and (b) represents the section of the drawing central portion of long side direction,
C () represents the section of the drawing right-hand end of long side direction.In the example in figure 2, show that the windup-degree at both ends is relative
In horizontal plane example each other for 2 degree.
PG thin plate 5 is more converted to potential energy closer to the end of long side direction, then kinetic energy, and speed more reduces.And, speed drops
When low, move to the width for becoming descending, and and sidewall contact.And, moment stop, change towards and round about
Advance.So repeatedly such that it is able to the energy consumption of irreducible minimum, easily change track in outlet and loop and walk on.
(d) of Fig. 2 schematically illustrates the magnetic flux distribution on magnet surface.
If magnet is configured so that, the peak of magnetic flux distribution is formed in the top of magnet row, in the different magnetic of magnetic
The border of iron row is formed about the paddy of magnetic flux distribution.
Further, since the magnetic field that formed of magnet for diamagnetic substance repulsive force as already described, not only
It is directly proportional to magnetic flux density B, and is that B dB/dz is directly proportional to the product of B and gradient dB/dz of its vertical direction.But, real
Border carries out various changes to the size of magnet and configuration, and changes the size of PG and tested, as a result, understanding B dB/dz
It is the trend same with magnetic flux density B (ignoring the absolute value of polarity).Thin to PG therefore, it is possible to the distribution according to magnetic flux density B
The stability of the levitation position of plate is illustrated.
In addition, according to the degree of crook of base plate described later and in order to improve above the magnet at width two ends
Magnetic flux density and adopt which kind of method, optimal torsion degree is different.In addition, optimal torsion degree is thin also according to PG described later
The accelerated method of plate 5 and different.
By magnet configuration on the base mounting plate after, it is also possible to cover and protect magnet list with magnetic thin slice of rubber system etc.
Face, and torsion degree can also be adjusted using for example two ends being the method such as are clamped with bench vice or pliers.
By such adjustment, the time that PG thin plate 5 can be made to encounter side wall 7 and contact is extremely short, subsequently becomes noncontact.
Therefore, because the energy loss that PG thin plate 5 is contacted and cause with side wall 7 is few, PG thin plate 5 is easily made to walk on.
As the soft magnetic material used by pedestal 2, using the sheet metal of strip, the sheet metal of the strip is by inhaling
Attached magnet and it is easily bent the mild steel of processing or ferrite-group stainless steel is constituted.The particularly ferritic stainless steel such as such as SUS430
Have both soft magnetism and enough corrosion resistances, and the surface treatment such as need not electroplate, so being selected as optimal material.
If the thickness of pedestal 2 is, for example, more than 1mm, the effect of magnetic flux density of magnet is improved i.e. as yoke material
Effect also become big, the intensity simultaneously as pedestal is also enough.And, the maximum magnetic energy product of the magnet for being used is bigger, thickness
Thicker, width is wider, then in order to increase the magnetic flux density of magnet, preferably increase the thickness of the pedestal 2 played a role as yoke.
On the other hand, when thickness increases, the overall weight of device also increases, and processing also becomes difficult.Therefore, the upper limit of thickness is 3mm,
And consider that such key element suitably determines.
Then, the degree of crook to base plate is illustrated.
As shown in (b) of Fig. 1, pedestal 2 is configured in long side direction bending raised downward.
PG thin plate 5 is more converted to potential energy closer to end, then kinetic energy, and speed is lower.And, speed is lower, then more can
Energy loss when reducing 5 contact side wall 7 of PG thin plate and changing direction, more easily walks on.
With regard to the flexibility of pedestal 2, such as in the case of being processed as arc-shaped with uniform radius of curvature r, if pedestal
When length is 2 α (radian) for the L elevation angle corresponding with the circular arc after processing, following formula is set up.
2 α r=L
α=L/ (2r)
And, the straight line for connecting the two ends of circular arc is tried to achieve by following formula with the distance between the circular arc of central portion h.In addition, h phase
When in the drop at the both ends on the basis of central portion.
H=r rcos α=r (1 cos α)
=r (1 cos (L/2r))
Become the gradient (inclination) at the both ends of maximum to be tried to achieve by following formula.
=tan (α)=tan (L/2r)
Consideration demonstrating effect, L is suitably assumed to longer 300mm, for example, is significantly set as radius of curvature r
During 4000mm, calculating α is 0.0375 radian (2.15 degree).
It is 2.8mm equivalent to drop apart from h, gradient tan (α) for becoming the both ends of maximum slope is also fairly small, is
0.038.Therefore, in such larger radius of curvature, the speed of travel of PG thin plate 5 is slack-off.Even so, also confirm due to not having
There is friction, it is possible to moving back and forth without any problems.
But, when radius of curvature is increased further, the drop h at two ends reduces, and reduces the kinetic energy conversion of PG thin plate 5
And save as the effect of potential energy.
Thus, it can be known that it is following as 4000mm or so to set r, and preferably further increase flexibility.
Equally, if L is 300mm, for example, increase flexibility and make radius of curvature r for same calculating is carried out during 1000mm,
Then α is 0.15 radian (8.6 degree), is 11.2mm equivalent to drop apart from h, becomes gradient tan at the both ends of maximum slope
(α) it is 0.15.
Can confirm that PG thin plate 5 also can be without a doubt when by flexibility increase radius of curvature so far forth
Move back and forth.Understand from the description above：By pedestal overall processing be bending when radius of curvature be preferably 1000mm～
4000mm or so.
In another device of the present invention, as shown in figure 3, the pedestal 21 be bent into towards downside in long side direction convex
Shape, and, the flexibility near two ends is more than the flexibility of central portion.
Compared with when pedestal to be integrally shaped to bending with identical radius of curvature, straight line moving region is able to maintain that
The speed of PG thin plate 5 is high speed, and can be slowed down before it will reach the side wall 7 near two ends.Therefore, it is possible to whole
Body improves speed sense.
As described above, in the case of the flexibility near two ends is increased, preferably the radius of curvature of central portion is 1/2 left
Right following.In order to the speed of the PG thin plate 5 of the length direction central portion of magnet row top is maintained, and improve the deceleration near two ends
Flexibility near two ends is preferably risen to more than 2 times of central portion by effect, i.e., preferred curvature radius is less than 1/2.
In addition, having had been acknowledged in the case that reduction radius of curvature increases flexibility, although also depend on composition magnetic
The geomery of the performance, thickness and PG thin plate 5 of the magnet of iron row, but till radius of curvature is for 500mm or so, not with magnetic
Iron surface is contacted.It is therefore preferable that radius of curvature is with 500mm or so as lower limit.
PG thin plate 5 is made in the case that outlet and loop change track travel, in order that the action of PG thin plate 5 is more stable,
Prevent which from coming off from magnet row, the magnet positioned at magnet column width direction two ends is played an important role.
For example in the case of five row configurations, in the direction of the width, magnetic flux distribution forms five peaks.But, only
In the case of the magnet of the identical maximum magnetic energy product of arrangement same shape size, the peak of the magnetic flux distribution at width two ends
Step-down.And understand, the magnet row of inner side are that the peak of the magnetic flux distribution of the magnet row top that PG thin plate 5 is walked becomes most
High.(d) of Fig. 2 schematic diagram illustrates the situation in the case that magnet is classified as five row.
In fact, Fig. 4 show the thickness as base material for 2mm SUS430 steel plate on, by neodium magnet with
The measurement example of magnetic flux distribution when the alternate mode of NS is arranged.It is 3mm that neodium magnet adopts thickness, width is 6mm, length
For 12mm, field orientation in thickness direction maximum magnetic energy product for 47MGOe magnet.Measure magnet surface and carry 1mm's
It is the magnetic flux distribution above magnet surface at 1mm on surface after aluminium sheet.Will also realize that according to the measurement example, from width
Magnetic flux density above second magnet of two terminal number of direction is uprised.
In the case of five row configurations, PG thin plate 5 is walked in the maximum second magnet row from two terminal numbers of magnetic flux density
Top, it is known that be easily separated from track.
For example, in the case that the desk or estrade that placed apparatus of the present invention does not measure up, or air-conditioning can not be avoided
Or in the case of the impact of the wind of blowout such as fan, it is known that PG thin plate 5 is easily come off from magnet row top.Particularly as rear institute
State, it is known that accelerate PG thin plate 5 from the nozzle blow out air of the present invention, and in the case of inverting which using guiding piece, due to
The blow-off direction of nozzle slightly offset from or blowout speed high low degree, PG thin plate 5 easily departs from from magnet row top.
In order to improve the problem, as make PG thin plate 5 be difficult to further to come off and being capable of stably reciprocating side
Method, with three kinds of methods shown below.
For example, in the apparatus of the present, as shown in figure 5, the magnet positioned at magnet column width direction two ends can be adopted
The neodium magnet 3 of row inwardly rolls oblique method.Now, as oblique method is inwardly rolled, in (a) of Fig. 5, pedestal 22 is employed
Bending machining becomes width inward at both ends side to become the pedestal of descending.
Here, inwardly rolling oblique angle to be suitably for 1 degree～10 degree.
This is the magnet at two ends due to for example as representative examples using the magnet of width 6mm, in the case of inclining 10 degree
The central authorities that arrange apart from magnet of corner rise
6mm × sin (10 degree)=1.04mm,
It is close to suspension distance of the PG thin plate apart from magnet.Therefore, the peripheral part bottom surface of PG thin plate 5 becomes easily to contact magnet
Surface.Slow down in contact, it is difficult to stabilized walking.In addition, when from horizontal finder, it is difficult to observe the outstanding of PG thin plate 5
Floating.It is therefore preferable that being less than 10 degree.On the other hand, if less than 1 degree, then its DeGrain.
If being configured so that magnet, such as in the case that PG thin plate 5 will be disengaged from, magnet surface and PG thin plate 5 it
Between distance shorten, increased repulsive force, PG thin plate 5 is inwardly rolled tiltedly, easily resets to original position.I.e., it is difficult to come off,
Stably can walk.
Further, following method can be adopted in the apparatus of the present：As shown in (b) of Fig. 5, can make to be configured at magnetic
The magnet at iron column width direction two ends is using the maximum magnetic energy product magnet 31 bigger than the maximum magnetic energy product of the magnet of central part.Such as
This, the peak of the magnetic flux distribution above the magnet at both ends can be uprised certainly further.
In order to improve such effect, preferably the maximum magnetic energy product of the magnet 31 at two ends is than the maximum of the magnet 3 of central part
Big more than the 3MGOe of magnetic energy product, in order to play more significant effect further, preferably big more than 5MGOe.
According to such magnet configuration, PG thin plate 5 is difficult to come off from magnet row top, being capable of stabilized walking.
(c) of Fig. 5 shows the profile of the width of other method.In the method, positioned at magnet column width side
Employ compared with the neodium magnet 3 for being located at inner side with identical maximum magnetic energy product to the neodium magnet at two ends and the thick magnet of thickness
32.In the method, as, in the magnet of identical maximum magnetic energy product, the magnetic flux density on the more thick then surface of thickness is bigger, because
The peak of this magnetic flux distribution is uprised.And, the surface of thick magnet 32 and the bottom surface of the PG thin plate 5 of the process that suspends thereon it
Between distance also shorten, therefore, suspending power correspondingly increases further, and PG thin plate 5 inwardly rolls tiltedly and is difficult to come off.
In addition, suspension distance of the PG thin plate 5 above magnet is for 1mm or so, therefore, the thickness difference of magnet be than the suspension
Apart from little below 0.7mm, in order to play significant effect, preferably more than 0.3mm.
The process described above can be applied in combination.It is for instance possible to use magnet is under the inner side inclination of width is
The method of the bigger magnet of the method on slope and combination maximum magnetic energy product.Or can be using the bigger magnetic of thicker and maximum magnetic energy product
Iron.
Fig. 6 schematically illustrates magnet columns for six row, and being curved processing to the width two ends of pedestal makes two
The surface of the magnet row at end becomes the example of descending towards inner side, shows in long side direction and is followed successively by (a) end, (b) end

Long side direction two ends are for about 3 degree of example near both ends using the angle of inclination for reversing the formed width of processing.
These angles are for about 1 degree at (b), the position of (d).
Under the angle of inclination of this degree, 5 magnetic suspension of PG thin plate, without frictional resistance between magnet surface, therefore
Can move to a low side.That is, can move in width, and conversion direction and change as walking track magnet
Row.Although with side wall instant shock when mobile, optimized by making the shape of PG thin plate 5 described later, size, that is, select
It is not contact with side wall in the state of width is stable, being capable of completely noncontact so as to straight line moving hereafter.
Used as one, (b) of Fig. 7 shows the SUS430 pedestal steel plate for rolling oblique 8 degree in width inward at both ends
On, the measurement example of magnetic flux distribution when being alternately arranged into N pole, S pole in the width direction.(a) institute of measurement position such as Fig. 7
Show, be the position of 1mm above the magnet surface of the row of width four.Neodium magnet is using identical with during the measurement carried out shown in Fig. 4
Magnet.
In (b) of Fig. 7, in order to be compared, with dotted line be also shown for width two ends inwardly do not roll oblique 8 degree and
Be on pedestal steel plate flat in the width direction similarly distributed magnet when, the magnetic flux distribution above magnet surface at 1mm.
According to the figure：Magnet is arranged on the basis of pedestal steel plate bending and makes the inside inclination of magnet surface tiltedly, by
This, improves the magnetic flux density at width two ends, and the PG thin plate 5 that walks thereon is difficult to come off.Particularly PG thin plate 5 is straight
Line is difficult to be contacted with side wall 7 when walking.Walking thereby, it is possible to make PG thin plate 5 is stable.
In these devices, it is also possible to from many countermeasure sides for guaranteeing 5 stabilized walking of PG thin plate having been described above
In case, the magnet for width two ends is arranged efficiently with following scheme：
(1) inclined in the way of the central step-down towards width；In addition,
(2) the configuration maximum magnetic energy product magnet bigger than the maximum magnetic energy product of each magnet of the magnet row of inner side；
(3) using the magnet that thickness is thicker than the thickness of each magnet of the magnet row of inner side.
In the apparatus of the present, in order that PG thin plate 5 is continued for changing the walking of track in outlet and loop,
One position in the straight line moving region of magnet row top or plural position are provided for the nozzle that blows, can be effective
Accelerate PG thin plate 5.
As PG thin plate 5 suspends, so there is no frictional resistance between the magnet as track, hinder mainly due to air
Power and slow down, tighter say due to less vortex flow loss and slow down.
The end that PG thin plate 5 is close to long side direction is additionally, since, and is moved in width and instantaneously encounters side wall,
So also producing energy attenuation.
Therefore, in the process of walking, from the rear blowing air of PG thin plate 5, accelerated, thereby, it is possible to hold for a long time
Continue and change track travel in outlet and loop, demonstrating effect can be improved further.
