Description

A kind of magnetic field shielding method

Technical field

The present invention relates to the shield technologies in magnetic field.

Background technology

For earth gravitational field, the graviational interaction of the centre of sphere, terrestrial gravitation are directed toward by the earth in tellurian any object It is a kind of force（Note：There is no the explanation of this word of force on physics dictionary, but physically have the concept of potential energy, force exists It is construed to cause the power of potential energy herein, for example to be exactly a kind of force be divided into gravitation and repulsion to gravity for magnetic field, is referred to as Magnetic potential power.）Relative position residing for object is higher, and potential energy is bigger, and the Level Change of object, gravitional force can be converted to kinetic energy.

Physically have been proven that earth gravitational field（Gravitational field）It is conservation law, conservation law cannot continue work done.Such as show Shown in Figure 1A, an object is in gravitational field, from starting point, is returned along arbitrary closed curve path, gravitation work done ring Road integral is zero.What the work done system significant as one necessarily recycled, so gravitational field can not possibly cycle work done.As The example of gravitation work done, hydroelectric generation, it is necessary to have the participation of solar energy, gravitation that could complete a power cycles.

For a permanent magnetism（It is different from electromagnetism）Magnetic field, the magnetic bodies in the magnetic field is by magnetic potential power（Magnetic potential power In accordance with identical charges repel each other the rule that there is a natural attraction between the sexes）Effect and move, so as to realize magnetic potential can arrive kinetic energy energy conversion.Class It is similar to gravitational field, a magnetic bodies is in inside magnetic field, and magnetic field is also impossible to cycle work done.（Note：Physically think magnetic field Not instead of conservation law, rotational field, but it is similar with gravitational field in terms of mechanical force work done.）And always there are starting point and end in magnetic field Point（The poles N, the poles S of permanent magnet）, magnetic bodies is in Origin And Destination both sides always by function and effect opposite effect power.And one Single length of magnetic field is always limited, it is also not possible to which there are one the circular magnetic fields of not Origin And Destination.So any meaning Figure recycles inside a magnetic field realizes that the imagination of externally persistently output net work is all difficult to realize.

It is logical with rotor in order to utilize magnetic field potential energy work done, conventional motors technical field, stator hot-wire coil to generate magnetic field The magnetic field interaction that electric coil generates, drive rotor rotation.It is rotated with rotor when rotor turns to two magnetic field interaction forces When the opposite position in direction, under the action of brush and commutator, the current direction of rotor coil changes, to which rotor coil produces Raw magnetic direction changes, and so that stator is interacted with rotor field, force direction is identical as rotor rotation direction, and rotor therefore can With lasting rotation.Therefore motor technology is to realize a kind of technology of the continuous external work done in magnetic field using magnetic direction is changed. Common motor is that stator and rotor all generate magnetic field by hot-wire coil, and permanent magnet motor is slightly different, and stator is by permanent magnetism material Material provides magnetic field, and rotor provides magnetic field by hot-wire coil, and periodically changes rotor current and magnetic field side by brush and commutator To, to make stator field interact with rotor field, generation active force identical with rotor rotation direction.

Either common motor or permanent magnet motor be all by commutator come change hot-wire coil current direction and Magnetic direction keeps stator identical as rotor rotation direction as the magnetic field interaction force of rotor, and hot-wire coil will consume electric energy.

Invention content

The present invention provides a kind of magnetic field shielding methods, can utilize magnetic field potential energy work done.Technical scheme is as follows：

A kind of magnetic field shielding method, the first magnet A（Or group）With the second magnet B（Or group）Pole pair is established, the first magnet A continuously leads to The field region of the second magnet B is crossed, in the case of the direction of motion for setting the first magnet A, force is born suffered by the first magnet A Magnetic shield is set between the magnetic pole surfaces movement locus face of area, the first magnet A and the second magnet B, with completely cut off the first magnet A with The magnetic field of second magnet B contacts, and makes to bear force suffered by the first magnet A and reduces or be zero, or reduces and bear force zone length.Make just Force work done is more than negative force work done.

The principle of the invention：

As shown in Figure 1A, object is physically demonstrated in the inside of a field, and field can not possibly cycle work done.But such as Figure 1B It is shown, it can but be proved with identical method：When an object in field is from starting point, edge is appointed across field border Closed curve of anticipating returns to starting point, and the work done of field is not zero.Similar, for a magnetic bodies in magnetic field, from Initial point sets out, and is returned along the arbitrary closed curve across magnetic field boundaries, magnetic potential power work done is not zero.This be this patent utilize magnetic The physics theory basis of the feasibility of potential energy work done.

This patent is in the case where stator and rotor are all made of permanent-magnet material, using magnetic field shielding method, to eliminate or subtract Between small stator and rotor field, with rotor rotation direction opposite effect power；Rotor is in magnetic potential power identical with rotation direction It is lasting to rotate under effect.In the case where not consuming electric energy, realize that magnetic potential can be to the conversion of kinetic energy.

As shown in Figure 2 A, a first magnet A, the second magnet B are established between the poles N and the poles S under quiescent conditions One magnetic field, there is boundary in magnetic field（Boundary concept may be disputable, and boundary herein is the concept on engineering significance, works as magnetic field Intensity very little, on it is studied the problem of influence negligible when, it is believed that have boundary）, there is no magnetic field except boundary.

But it as illustrated in figures 2b-2f, is then established between A and B as outside boundaries the first magnet A of placement in the second magnet B One magnetic field, certain second magnet B itself are also affected.Just there is magnetic potential power between A and B at this time, attract or arranges Reprimand.With the variation of position between A and B, magnetic field intensity changes, and distance is closer, and magnetic field intensity is bigger, and magnetic potential power is bigger. Here it is so-called dynamic magnetic fields.

Similarly, except a boundary magnet B1, another magnet B2, B3 are placed, then magnetic field reconstructs between B1, B2, B3, The first magnet A, A is placed between B1, B2 and B3 to be acted on by magnetic potential power certainly.

About positive and negative force.

Magnet is known as positive force by power identical with the direction of motion of setting, and magnet is by the direction of motion phase with setting Anti- power is known as negative force.Force is worth positive and negative point, related with the setting direction of motion.Negative force peak value may with positive force peak value It is equal may also be unequal, it is related with magnetic field structure.The magnetic potential power component for only considering magnet movement direction, is perpendicularly to the direction of movement Magnetic potential power component the movement of magnet is not influenced, this specification does not consider, similarly hereinafter.

As shown in Figure 3A, if the first magnet A（N under upper S）The poles N move from left to right, by the second magnet B（N under upper S） The poles S, when the first magnet A is in the poles the S central process of magnetic field B, the positive force that A is become larger by one reaches the poles S center When, positive force reaches maximum；When the poles the S center of magnet B, positive force drastically becomes smaller, and becomes greatly bearing force；Negative gesture Power is gradually reduced, and becomes a smaller negative force.（Work as A（S under upper N）The poles S move from left to right, by the second magnet B（Under upper N S）The poles N, it is identical, do not state herein.）

As shown in Figure 3B, if the first magnet A（N under upper S）The poles N move from left to right, by the second magnet B（S under upper N）N Pole, when A is in the poles the N central process of magnetic field B, the negative force that A is become larger by one, when reaching the pole centers N, negative force reaches To maximum；When the center of the poles N, negative force drastically becomes smaller, and becomes great positive force；Then positive force is gradually reduced, and is become For a smaller positive force.（When the poles S of A move from left to right, by the poles S of the second magnet B, process is identical, herein not It states.）

As shown in figure 4, the poles N for setting one piece of first magnet A move from left to right, by the second magnet B（The left right S of N）, when A is close In the central process of magnetic field N pole, the negative force that A is become larger by one, when reaching the pole centers N, negative force reaches maximum；Then Negative force drastically becomes smaller, and becomes very big positive force；Positive force is gradually reduced, and becomes a smaller positive force；When A moves closer to the poles S When, positive force becomes larger；It then strongly reduces, becomes a greatly negative force, finally bear force and be gradually reduced.（When the poles S of A Move from left to right, or by left S right magnetic fields N, process completely on the contrary, or it is identical, do not state herein.）

As shown in figure 5, when the magnetic field group that the first magnet A is made up of multiple second magnet B1, B2, Bn, A stressing conditions phases Together, only stress curve mechanical periodicity.Or multiple A1, A2, An when passing sequentially through B and B1, B2, Bn group, then stress curve is folded Add.

Fig. 3 A, Fig. 3 B, Fig. 4 and Fig. 5 example in, the first magnet A of setting is moved from left to right, is only united for sake of convenience One.It can also set and move from right to left, then the first magnet A stress is symmetrically opposite.First magnet A nevertheless suffers from size direction week The positive and negative magnetic potential force effect of phase variation.

Movement is an opposite concept, such as moves, also is understood as, the first magnetic from left to right for the first magnet A above Body A is static, and the second magnet B is moved from right to left.

Rule Summary, like pole is close to each other, and force is negative；Like pole is located remotely from each other, and force is just；Opposite pole Close to each other, force is just；Opposite pole is located remotely from each other, and force is negative.

In short, positive and negative magnetic potential force effects of the first magnet A by size direction mechanical periodicity.

The stress of A is more complicated in above procedure, different structure, and stress variation is also different, in order to express conveniently, the first magnetic The stress of body A is simplified with the change procedure curve of displacement.Area between curve and reference axis represents magnetic potential masterpiece work value.

Specific implementation mode

When the first magnet A is only in the case of by the active force in the second magnetic fields magnet B, and negative force area and positive force area pair In the case of title, it is equal with positive potential power work done to bear force work done（First system friction resistance is not considered）, the first magnet A can not possibly be certainly It is dynamic to pass through a complete second magnet B, it is also not possible to export net work.Only make work value in positive force area and is more than negative force area work In the case of work value, magnetic field is possible to externally export net work.

Make work value more than negative force area in order to which Shi Zheng force area makees work value, this patent uses magnetic field shielding method, makes the first magnetic Body A and the second magnet B breaks off or reduces magnetic field in negative force area and contacts, then force reduces or disappears, and negative force area makees accordingly Work value reduces.

Since the magnetic resistance of magnetizer is small, and magnetic field magnetic line has the characteristic along resistance minimal path, when a magnetizer is in In one magnetic field, magnetizer is magnetized, and the magnetic line of force distribution in former magnetic field changes.The poles N in magnetizer and magnetic field, the poles S it Between magnetic potential power show as attracting.This patent utilizes above two characteristic of magnetizer, and the first magnet A and the second magnet B is made to exist Magnetic field contact is broken off or is reduced in negative force area, makees work value to reduce negative force area.

As shown in figs 6 a-6 c, the poles N of the first magnet A and the second magnet B（The left right S of N）Form double magnetic pole pole pairs.First Magnet A is moved from left to right.If without shielding part, the first magnet A is successively by negative, positive, positive and negative magnetic potential force effect（According to same Property magnetic pole is close to each other, and force is negative；Like pole is located remotely from each other, and force is just；Opposite pole is close to each other, and force is just； Opposite pole is located remotely from each other, and force is the principle born.Similarly hereinafter）.A shielding part is fixed Liang Gefu force area is each.Such as Fig. 6 A institutes Show, when N ultra-Left sides of the first magnet A in the second magnet B, due to the shielding action of shielding part, the first magnet A and the second magnet B does not have a magnetic field exchange interaction, and magnetic potential power is zero suffered by the first magnet A；As shown in Figure 6B, when the first magnet A is completely into magnetic field B The ultra-Right sides N, the poles N of the second magnet B and the poles N of the first magnet A repels each other, and is positive force, while the poles N of the first magnet A are by the The attraction of the poles S of two magnet B is positive force, two positive force superpositions；As shown in Figure 6 C, when the first magnet A is completely into the second magnetic The ultra-Right sides S of body B, i.e., completely into blind zone, the first magnet A does not have magnetic field to exchange with the second magnet B, and magnetic potential power is zero.Reason By upper, in the case of armoured magnetic field, the first magnet A by zero, just, just, zero magnetic potential force effect, force displacement diagram shows, just Work value is more than negative work value.First magnet A can be in positive work area store kinetic energy, and breaks through Liang Ge negative work area, can externally export net work.

As shown in Figure 6 D, in fact, when the first magnet A enters magnetic field from blind zone, due to entry-end effect, the first magnet A still can be repelled by the poles N of the second magnet B, be acted on by a smaller negative force, but operating distance is shorter, negative work value It is smaller；Similarly, when the first magnet A leaves from magnetic field, into the second magnet B on the right side of shielding area when, still by the second magnet B The poles S attraction, be a smaller negative force, but operating distance is smaller, and negative work value is smaller.In order to simplify problem description, below It is omitted in description, but is still shown in force displacement diagram.

Since magnetic potential power of the first magnet A between shielding part shows as attracting in all directions, attraction and first The direction of motion of magnet A is vertical, so the sum of work done is zero between the first magnet A and shielding part, the motion state of the first magnet A It is constant, or more example do not consider, similarly hereinafter.

Similarly, as shown in fig. 7, the poles S of the first magnet A and the second magnet B（The left right S of N）Form pole pair, the first magnet A It moves from left to right.First magnet A is successively by positive and negative, negative, positive magnetic potential force effect.A shielding part is fixed in negative force area, is shielded Part covers the middle part of the second magnet B.First magnet A is in left side by positive force（Gravitation）, middle part blind zone do not stress, right side by Positive force（Repulsion）.In the case of armoured magnetic field, the first magnet A by just, zero, zero, positive magnetic potential force effect, the first magnet A Obtain positive work.When the poles N of the first magnet A and the second magnet B（The left right N of S）Pole pair is formed, the first magnet A is moved from left to right；Or The poles S of first magnet A and the second magnet B（The left right S of N）Form pole pair, the first magnet A moves from right to left, stressing conditions with Upper example is identical, is omitted.

Similarly, as shown in figure 8, when shielding part covers the centre and right side of the second magnet B, the poles S and second of the first magnet A The poles N of magnet B form pole pair, and the first magnet A is moved from left to right.First magnet A on the left of the second magnet B by positive force, It does not stress in intermediate and right side blind zone.First magnet A by just, zero, zero, zero magnetic potential force effect, the first magnet A obtains positive work. Form double magnetic pole attraction type pole pairs.

Similarly, as shown in figure 9, when shielding part covers the centre and left side of the second magnet B, the poles S and second of the first magnet A The poles S of magnet B form pole pair, and the first magnet A is moved from left to right.First magnet A by zero, zero, zero, positive magnetic potential masterpiece With the first magnet A obtains positive work.Form double magnetic pole repulsion type pole pairs.

Similarly, as shown in Figure 10, when shielding part covers the left side of the second magnet B and center-right and right side, the first magnet A The poles N of the poles N and the second magnet B form pole pair, the first magnet A is moved from left to right.First magnet A by zero, just, zero, Zero magnetic potential force effect, the first magnet A obtain positive work.Form double magnetic pole repulsion type pole pairs.

Similarly, as shown in figure 11, when shielding part covers the left side of the second magnet B and center-left and right side, the first magnet A The poles S of the poles N and the second magnet B form pole pair, the first magnet A is moved from left to right.First magnet A by zero, zero, just, Zero magnetic potential force effect, the first magnet A obtain positive work.Form double magnetic pole attraction type pole pairs.

Similarly, as shown in figure 12, the axis of the second magnet B is perpendicular to the direction of motion of the first magnet A, the N of the first magnet A Pole and the poles N of the second magnet B form pole pair, and the first magnet A is moved from left to right.First magnet A is successively by negative, positive magnetic potential power Effect.A shielding part is fixed in negative force area.First magnet A is obtained positive work by zero, positive magnetic potential force effect, the first magnet A.It is formed Single magnetic pole repulsion type pole pair.The poles S of first magnet A and the poles S of the second magnet B also form single magnetic pole repulsion type pole pair, from Slightly.

Similarly, as shown in figure 13, the axis of the second magnet B is perpendicular to the direction of motion of the first magnet A, the N of the first magnet A Pole and the poles S of the second magnet B form pole pair, and the first magnet A is moved from left to right.First magnet A is successively by positive and negative magnetic potential power Effect.A shielding part is fixed in negative force area.First magnet A by just, zero magnetic potential force effect, the first magnet A obtains positive work.It is formed Single magnetic pole attraction type pole pair.The poles S of first magnet A and the poles N of the second magnet B also form single magnetic pole attraction type pole pair, from Slightly.

As shown in figure 14, further, in order to make the first magnet A that can make lasting movement, can arrange polylith magnet B1, B2、Bn.By the above rule, shielding part is set.First magnet A is successively by the positive potential power work done of magnet B1, B2, Bn, the first magnet A can be accelerated, or externally export net work.

As shown in fig. 15 a and fig. 15b, or polylith magnet A1, A2, An are arranged, pass sequentially through the second magnet B,（More than pressing Shielding part is arranged in rule.）Positive force work done successively, the first magnet A can be accelerated, or externally export net work.

As shown in diagram 16A and Figure 16 B, further, in order to make the first magnet A obtain the magnetic potential power of bigger, storage is more More kinetic energy can be arranged multiple magnet A1, A2, An, arrange according to certain rules, pass sequentially through magnetic field group B1, B2, Bn.By with Shielding part is arranged in upper rule.Magnet group A1, A2, An is acted on by magnetic potential power simultaneously, and magnetic potential power is multiplied.

According to principles above, some mechanisms are designed, the external output net work that magnetic potential power can continue, magnetic potential can be converted into dynamic Can, electrical power generators can also be driven.

As shown in Figure 17 A, the poles the N poles S of the poles S of the first magnet group A and the second magnet group B form double magnetic pole pole pairs, magnetic Body disk arranges, and shielding part is arranged between two adjacent magnets, and shielding part is anchor ring.First magnet group A is fixed on On rotor disk, wheel disc and axis connection；Second magnet B or second magnet group B1, B2, Bn are fixed on stator wheel disc, stator Coupled by bearing with shaft, roller end has shaft coupling, can couple with external generator or other power-equipments.

By pole pair.

About magnetic field, since there is no " magnetic charge ", any one magnet has and the only poles N and the poles S.Magnetic of different shapes Body is formed by magnetic field shape difference.

Magnet can be integrally formed by magnetic material merely, can also be to be coupled with magnetizer material by magnetic material It forms.Magnetic pole can be in the end face of magnet, can also be in the side of magnet.As shown in Figure 18 A, Figure 18 B and Figure 18 C.

Magnetic material mainly has metal alloy magnet, including nd-fe-b magnet, samarium cobalt magnet, alnico magnet, ferrite Magnet etc..

Magnetizer, without magnetism, can be magnet magnetized, magnetic resistance is small, be easy to magnetic flux by material.

The material of magnetizer mainly has pure iron, mild steel, iron Si system alloy, iron aluminum series alloy, iron silicon aluminum series alloy, ferronickel It is alloy, iron Co-based alloy, soft magnetic ferrite, amorphous soft magnetic alloy, super-microcrystalline soft magnetic alloy, waits materials.

The a certain magnetic pole of pole pair, a certain magnetic pole of the first magnet A and the second magnet B are established magnetic field and are contacted, between each other The effect of mechanical force is generated, the two can perform relative motion under the mechanical force, be known as establishing pole pair.Two magnetic fields are mutual Effect does not divide with passive actively.Relative motion between the two is either translation, can also be rotation.

Theoretically, arbitrary two blocks of magnet could set up pole pair, but be designed as machine, and economy, validity are weights The considerations wanted.From the point of view of planing machine, it should make full use of magnetic field, magnetic field that should concentrate, intensity is high, so magnet Shape design should advantageously form the small magnetic field of concentration, dispersion degree.The two poles of the earth characteristic of magnet is on the contrary, the two of same magnet should be avoided Pole influences each other.

The Interaction Force size of two magnetic pole of pole pair and many with the factor of change in displacement rule is influenced, wherein Lateral distance between the relative angle of two magnetic pole surfaces and two magnetic poles（Perpendicular to direction of relative movement）Two factors are than heavier It wants.

It is the static magnetic field of several typical magnets as shown in Figure 19 A to 19C：

1. bar-shaped magnet, the magnetic line of force is spread around from the extreme portions N, is then gathered in the poles S.When two magnets establish pole pair, The only a small part magnetic line of force exchanges, and magnetic potential power is small, and efficiency is low.

2.U type magnets, the magnetic line of force extremely extend towards same direction from N, turn two an angle of 90 degrees degree, reach the poles S.It is most of The magnetic line of force is in same direction, and when two magnets establish pole pair, most of magnetic line of force can exchange, and magnetic potential power is big, efficient. But the magnetic line of force even turns two an angle of 90 degrees degree, and reluctance force is larger, and dispersion degree is larger, and the magnetic potential power being perpendicularly to the direction of movement is larger, fortune Moving part frictional resistance is larger.

3.C type magnets, the magnetic line of force reach the poles S from the extreme faces N, along straight line.The magnetic line of force is more straight, and reluctance force is small, point Divergence is smaller.Be conducive to establish efficient pole pair.

Magnetic field can reconstruct, and multiple magnets arrange according to certain rules, and magnetic field structure changes.

As shown in figure 20, it is that several typical magnetic fields reconstruct example.Magnetic pole both sides magnetic direction is always on the contrary, the period becomes Change.

As shown in figure 21, two magnets could set up pole pair in any angle, but validity is different.

As shown in figure 22, in magnet cross section, surrounding could set up pole pair.As long as relative motion is interference-free.

Pole pair can also can be established in magnet end face in magnet side.

Pole pair can be divided into following a few classes：1. single pole type（It can be divided into again for attraction type, repulsion type）, 2. pairs of pole types.

Single pole type, the poles N of the first magnet A（Or the poles S）With the poles S of the second magnet B（Or the poles N）Magnetic poles pair, two magnetic It attracts each other between pole, is attraction type, as shown in Figure 3A；The poles N of first magnet A（Or the poles S）With the poles N of the second magnet B（Or S Pole）Magnetic poles pair, it is mutually exclusive between two magnetic poles, it is repulsion type, as shown in Figure 3B.

Double pole types, the pole N, S magnetic poles pair of any pole of the first magnet A and the second magnet B, gravitation, repulsion are simultaneously Effect.In the mutual motion process of first magnet A and the second magnet B, the first magnet A alternately crosses the pole N, S of the second magnet B. As shown in Figure 4,5.

First magnet A can be formed only by one, can also by one group of A1, A2, An or multigroup A11, A12, A1n, A21, A22, A2n, Am1, Am2, Amn are rearranged according to certain rules.It is connected between group or for synchronous rigid between multigroup.Second Magnet B is as the same.

First magnet A described above, the second magnet B, essential identical, shape, magnetic field intensity, material, identical also may may be used Can be different, title difference is convenient only for narration.

Magnetic field reconstructs between second magnet B group inner magnets, can also be reconstructed between the first magnet A group inner magnets.First Magnetic field interaction between magnet A and the second magnet B is dynamic magnetic field.

To simplify problem, herein often with an an a first magnet A and second magnet B or first magnet A and more than one piece Second magnet group is research object.Assuming that the first magnet A continues through the magnetic field of the second magnet B or the first magnet A is continued through The magnetic pole of second magnet group, a certain magnetic pole of the first magnet A and the second magnet B form magnetic pole Thermodynamic parameters, and draw magnetic potential Power and displacement relation figure.When first magnet group is by the second magnet B or the second magnet group, the superposition of force figure.

First magnet A can form stator component, can also form rotor part, and the second magnet B is as the same.

First magnet A, the second magnet B can be cylindrical surfaces in the arrangement architecture feature of stator or rotor, can be that circle is flat Face can be circular conical surface, can also be linear type（Magnetic suspension train, electromagnetic railgun etc.）.

By shielding part.

Magnetic field magnetic line has the characteristic extended along resistance minimal path, and since the magnetic resistance of magnetizer is small, the magnetic line of force is in magnetic conduction Resistance in body is less than resistance in air, and when a magnetizer is in a magnetic field, magnetizer is magnetized, the magnetic force in former magnetic field Line distribution changes, and a part of magnetic line of force extends along magnetizer.The magnetic line of force can be directed to the advantageous side of machine work done To.It is larger with the inlet and outlet resistance ratios that enter air from magnetizer that the magnetic line of force from air enters magnetizer, so the magnetic line of force penetrates The resistance of multilayer magnetizer is very big, using this characteristic, can completely cut off the magnetic field for generating and bearing force, make the magnetic line of force along resistance smaller Path extend, to enhance the intensity in the magnetic field for generating positive force.Magnetic potential power between the poles N in magnetizer and magnetic field, the poles S is equal It shows as attracting.Shielding part is made of magnetizer material.The following structural features of shielding part：

1. flake reduces volume, cost-effective.

2. multilayered structure increases resistance, the magnetic line of force for penetrating shielding part is reduced.

3. between the apparent motion track plane in two magnetic pole of pole pair.

4. the negative force area in pole pair.

5. being parallel to the shielding part of pole pair direction of relative movement, can be handed over the magnetic line of force between two magnetic pole of shaded pole pair It changes；Parallel shielding part is arranged in segmentation overlay, not only can also completely cut off magnetic field with armoured magnetic field.As shown in figure 23.

6., as shown in figure 24, both can be with two magnetic pole of shaded pole pair perpendicular to the shielding part of pole pair direction of relative movement Between the magnetic line of force exchange, and negative force area magnetic field can be completely cut off, to enhance positive force area magnetic field intensity.

7. the shielding part of guide frame both can completely cut off magnetic field, and can optimize with armoured magnetic field as shown in figure 25 Positive force area magnetic field structure.

8. or more 5,6,7 united application, as shown in figure 26.

9. shielding part can play shielding action at any angle, as shown in figure 27.

10. width and shield effectiveness relationship, wider, shield effectiveness is good, and volume is big, of high cost, as seen in figs. 28 a and 28b.

11. the distance between shielding part and magnetic pole, position relationship.Close with pole pitch, shield effectiveness is good, shielding part and magnetic Pole gravitation is big, and required precision is high.As shown in figs. 29 a and 29b.

12. the advanced magnetic pole of shielding part, shield effectiveness is good, and positive potential masterpiece work value reduces, and bears force peak value and reduces；Shielding part is stagnant Magnetic pole afterwards, shield effectiveness is poor, and negative force makees work value increase, bears force peak value and increases.As shown in figure 30.

13. for double magnetic pole pole pairs, shielding part is fixed on the magnet for providing two magnetic poles (pole N, S) or directly On connected element, the second magnet B as mentioned above, and the stator or rotor that are connected with the second magnet B.Consider this chapter Sub_clause 11, shielding part should be fixed on close to another pole, such as shielding part on the second magnet B, then far from the magnetic pole of fixed mask part It shielding part surface should be close to the first magnet A.As shown in figure 31.

14. for single magnetic pole pole pair, shielding part can be fixed on any one pole magnet of pole pair or coupled Element on, on the first magnet A or B and stator or rotor as mentioned above.Consider that this chapter Sub_clause 11s, shielding part are answered Magnetic pole far from fixed mask part is fixed on close to another pole, such as shielding part on the second magnet B, then shielding part surface should be leaned on Nearly first magnet A, vice versa.As shown in Figure 32 A and 32B.

15. for single magnetic pole pole pair, shielding part is all arranged in the two poles of the earth of pole pair, and shield effectiveness is more preferable.That is the first magnet A Shielding part is all set with the second magnet B.As shown in Figure 33 A and 33B.

16. the shielding part setting in several typical reconstruct magnetic fields.As shown in Figure 34 A to 34G.The setting of this example shielding part is only most Excellent promotion, if opposite（Or it is opposite）Shielding part is arranged in position, is still possible, but economy is different.Shielding part should The weaker magnetic field of shielding, retains stronger magnetic field.Once it is determined that shield part position, if determining the magnetic with its magnetic poles pair again Pole（Such as the poles N）, then the direction of motion uniquely determine.So the magnetic pole three of shield part position, the direction of motion, pole pair is related.

17. shielding part has magnetic field to exchange, shows as to rotor work done and stressing influence between the first magnet A and shielding part Gravitation, in most of region of shielding part, which is each perpendicular to the first magnet A directions of motion, is to the first magnet A works done Zero.Only have an impact in the first magnet of gravitation pair A movements of shielding part end regions, but the first magnet A is at the both ends of shielding part By graviational interaction, only there is shadow in two power direction equal in magnitude on the contrary, be zero to the sum of first magnet A works done to the distribution of force of A It rings.The above force displacement diagram does not consider the influence.

By the relationship of pole pair and shielding part.

The core technology of this patent be form machine driving part-permanent magnet and shielding part relationship, do not lie in as What design rotor, stator, bearing and connecting relation between them, does not lie in the structure feature-such as magnetic pole table of pole pair yet The distance between the relative angle in face, etc., do not lie in structure feature-such as cylindrical surface, disk, the straight line of stator, rotor Deng.These features are the conventional design of motor field or logical knowledge.So cannot be with the structure of different connecting relations, pole pair Feature, the structure feature of stator rotor evade the protection domain of this patent.

The magnet of magnetic poles pair, can be bar shaped, c-type, U-shaped and other any shapes, and not with upper magnet It is different with magnetic field reconstruct caused by arrangement, but significant pole pair can be constituted, so this patent cannot be evaded with this Protection domain.Pole pair can be arranged on cylindrical surface, can also be arranged on disk, on circular conical surface, can also be straight line Type all belongs to the protection scope of this patent.Parallel, vertical, guide frame of shielding part of various structures etc., as Figure 23,24, 25, shown in 26,27, armoured magnetic field can be played the role of, so the protection domain of this patent cannot be evaded with this.

The structure feature of pole pair is considered with pole pair in stator or the arrangement architecture of rotor, and the shape of shielding part is each It is different.For example, corresponding to cylindrical surface, the shape of shielding part may be cylindrical surface, it is also possible to be circular ring shape；It is flat corresponding to circle Face, it is also possible to be circular ring shape or cylindrical surface；It is the part or circular ring shape of circular conical surface corresponding to circular conical surface；Corresponding to linear type, For rectangle.It is above ideal situation, shielding part can also be made other shapes, such as ellipse, round etc..So Cannot be different with the shape of shielding part, and evade the protection domain of this patent.

Ideal situation, shielding part should shield all negative force as far as possible, but if only the negative force of a shielding part, The made positive work of magnetic potential power has been above negative force work done, and machine may remain able to work.So cannot be with the size of shielding part Difference, and evade the protection domain of this patent.As shown in figs. 28 a and 28b.

Ideal situation, the position of shielding part should shield the magnetic field for generating and bearing force as far as possible, retain generate positive potential as far as possible The magnetic field of power, ibid reason, retains the negative force of a part or a part of positive force of loss, as long as positive work is more than negative work, machine is still It can so work, so the scope of this patent cannot be evaded with this.As shown in Figure 29 A, 29B, 30.

For one such as Fig. 3 A, Fig. 3 B and symmetric magnetic field shown in Fig. 4（Positive work is symmetry equivalent with negative work）, in pole pair Any position（Except magnetic pole midpoint）The magnetic field for shielding arbitrary size region can obtain the case where positive work is more than negative work（Note：Such as Fruit shields positive work area, changes the direction of motion, negative work area becomes positive work area）, so the scope of this patent cannot be evaded with this.

Shielding part is generally laminar permeability magnetic material, if magnetic field intensity is high, there is one since magnetic field intensity is had nothing in common with each other Point magnetic field penetrates readily through shielding part, influences shield effectiveness, polylith magnetizer at this moment can be arranged, so cannot be with the number of magnetizer Amount is different, can not be with the thickness of magnetizer, to evade the scope of this patent.Machinery industry passage may be used in shielding part Various methods are fixed on the first magnet or the second magnet or on rotor stator, for example, welding, riveting, pin joint, hinged, bolt, Screw, embedded, interference fit, clearance fit, fusion etc..Since magnet described above can be by magnetic material and magnetizer Couple and the material of shielding part is also magnetizer, if shielding part and first and second magnet are by the way of fusion Connection, or the magnetizer of composition magnet can be processed into the shape for being of virtually shielding action, then it cannot in practice Clearly distinguish shielding part and magnet.Therefore it cannot evade the protection domain of this patent with this.
