[0044] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0045] The present invention provides a self-deflecting monopole permanent magnet, comprising:

[0046] The main magnet 1 is used to store magnetic energy and output magnetic energy;

[0047] The antimagnetic layer 3 is used to increase the density of magnetic force lines when outputting magnetic energy;

[0048] The magnetic conductor 2 is used to reflect the internal magnetic lines of force back so that the magnetic lines of force can only be output at one end;

[0049] The anti-magnetic layer 3 is disposed between the main magnet 1 and the magnetic conductor 2 .

[0050] Preferably, it also includes a shielding layer 4 for completely guiding the leakage magnetic field lines of the outer magnet into the interior of the magnet, and the main magnet 1, the anti-magnetic layer 3 and the magnetic conductor 2 are arranged inside the shielding layer 4.

[0051] Preferably, it further comprises a heat insulation layer 5 , which is a hollow shell, and the main magnet 1 , the anti-magnetic layer 3 , the magnetic conductor 2 and the shielding layer 4 are arranged inside the heat insulation layer 5 .

[0052] Preferably, the material of the anti-magnetic layer 3 is anti-magnetic material, and the material of the magnetic conductor 2 is a sheet-shaped magnetic conductor.

[0053] Preferably, the material of the shielding layer 4 is a polymer sub-superconducting material, and the material of the thermal insulation layer 5 is a polymer thermal insulation material.

[0054] Preferably, the shape of the permanent magnet includes a cube, a rectangular parallelepiped, a round body, or other deformed bodies.

[0055] The three characteristics of the permanent magnet are: the characteristics of opposites attracting and likes repelling, the characteristics of the center symmetry of the magnetic force lines, and the characteristics of the magnetic field balance at both ends of the N and S poles. That is to say, even if the permanent magnet is divided into sufficiently small individuals, its three characteristics still exist, thus limiting the application scope and use value of the permanent magnet. The purpose of the implementation case of the present invention is to provide a method of making the magnetic field at both ends of the N and S poles of the permanent magnet lose balance, and break the symmetrical magnetic force lines of the N and S poles, make the center asymmetric, let the magnet output a strong magnetic field magnetic force line at one end of the magnet, and lose the center symmetry of the magnetic force line, so that the magnetic force line of the permanent magnet is transformed into a magnetic monopole permanent magnet, with a permanent magnet with a deflection monopole magnetic field with one end deflected to one side, and arrange the permanent magnets of N monopole deflection magnets on the circumference of the motor stator and the circumference of the rotor, so that there is a rotating directional magnetic field similar to that of the motor, and the rotor can be installed to generate directional rotation. Realizing the real magnetic energy conversion, the self-deflecting monopole permanent magnet is the only key component for releasing magnetic energy.

[0056] The following is a further description of each component:

[0057] The main magnet 1 is composed of a high-strength permanent magnet, such as ferrite, neodymium iron boron, etc., and its working principle is to store magnetic energy. The greater the magnetic field strength, the greater the magnetic energy, and the greater the conversion of magnetic energy into mechanical energy;

[0058] The antimagnetic layer 3 is an energy-gathering layer made of antimagnetic material, and its working principle is to make the density of magnetic force lines introduced stronger when outputting magnetic energy;

[0059] The magnetizer 2 is composed of a magnetic sheet material with very small magnetic resistance, and other magnetic materials with higher magnetic permeability can also be used. Its working principle is that when outputting magnetic energy, most of the magnetic lines of force can be introduced from one end to the other end, also called a reflection layer. It is similar to a mirror image pair and reflects the internal magnetic lines of force back before they reach the terminal, so that the magnetic lines of force cannot gather at the other end. Therefore, the magnetic lines of force can only be forced to output at one end, forming a permanent magnet with only a unipolar magnetic field. The magnetic material can be a silicon steel sheet, a spherical alloy sheet, or a magnetic material such as pure iron;

[0060] The shielding layer 4 is composed of a polymer sub-superconducting material. Its working principle is to completely guide the magnetic field lines of the outer magnet to the inside of the magnet when outputting the magnet energy, and basically not show magnetism to the other outer end. If this layer is not set, there will be leakage magnetic field. The sub-superconducting material can be a polymer material such as graphene;

[0061] The thermal insulation layer 5 is composed of a polymer thermal insulation material. Its working principle is that when the magnetic energy is output, when the "magnetic energy prime mover" runs at high speed, the friction resistance of mechanical movement and a small amount of magnetic resistance eddy current will cause heat. In order to reduce the influence of thermal radiation on the magnet, the magnet is subjected to necessary thermal insulation protection. Without the thermal insulation layer 5, the temperature will be too high. The temperature resistance of general magnets (NdFeB) can only be maintained below 80°C. This solution can achieve that the magnet will not be affected by temperature below 100°C. The thermal insulation material can be aluminum silicate material or other thermal insulation coating materials.

[0062] The present invention is a permanent magnet with a single magnetic pole, which can generate self-deflection motion without the action of an external magnetic field. The uniqueness of this permanent magnet is that it does not require external energy or excitation coils, and can generate self-deflection motion only by its own magnetism.

[0063] The working principle of the self-deflecting monopole permanent magnet mainly depends on the magnetic anisotropy of the permanent magnet and the effect of the magnetic field. When the permanent magnet is in an external magnetic field, its magnetization vector is acted upon by the magnetic field, causing the magnetization vector to gradually tend to be consistent with the direction of the magnetic field. Due to the magnetic anisotropy of the permanent magnet, the rotation of the magnetization vector will generate a self-deflection torque inside the permanent magnet, causing the external magnetic lines of force of the permanent magnet to produce self-deflection motion. The magnetic field formed by the permanent magnet is as follows: Figure 3 As shown, there are three different magnetic field strengths: high, medium and low.

[0064] The product has the following features:

[0065] 1. No external power supply required: Self-deflecting monopole permanent magnets do not require external power supply or excitation coils, and can generate self-deflection motion only by their own magnetism, which gives them great advantages in energy saving. For example, the magnetoelectric generator, which has been developing rapidly recently, can save half of the magnetoelectric generator magnet material by using self-deflecting monopole permanent magnets, and can greatly improve the power generation efficiency.

[0066] 2. Simple structure: The structure of the self-deflecting monopole permanent magnet is relatively simple, mainly composed of permanent magnets and supporting components, and is easy to produce and maintain. Compared with monopole monopole magnetic materials, the production process is simple, the production cost is low, the magnetic efficiency is high, and it is easy to mass produce without special expensive equipment. Monopole monopole magnetic materials require multi-metal polymerization, the production process is complex and difficult, the magnetic efficiency is low, special expensive equipment is required, the production cost is high, and it has not been mass-produced so far.

[0067] 3. Fast response speed: The response speed of the self-deflecting monopole permanent magnet is very fast, and it can reach a stable self-deflection state after magnetization is completed in a short time.

[0068] 4. Strong controllability: By changing the direction and strength of the external magnetic field, the rotation speed and direction of the self-deflecting monopole permanent magnet can be controlled, making it highly flexible in practical applications.

[0069] 5. Strong durability: The self-deflecting monopole permanent magnet has strong durability, can maintain stable self-deflection performance for a long time, and has a long service life.

[0070] Self-deflecting monopole permanent magnet is a new type of permanent magnet with unique working principle and product characteristics. It has great advantages in energy saving, response speed, controllability, durability, etc. and has broad application prospects.

[0071] The manufacturing process of monopole permanent magnets can be divided into bonded monopole permanent magnets (such as Figure 1-4 As shown), and sintered monopole permanent magnets (as Figure 5-9 Take the square magnet manufacturing process as an example.

[0072] The manufacturing method of the bonded monopole permanent magnet is as follows, comprising the following steps:

[0073] Step S1: Select the type and brand parameters of the main magnet 1, cut the blank magnetic material into a cube shape, and polish it for standby use;

[0074] Step S2: stamping the magnetic conductive material into a cube shape and stacking and bonding them for standby use;

[0075] Step S3: Diagonally cut the square main magnet 1 formed in step S1 and the square conductive magnet 2 formed in step S2 by wire cutting to form triangles respectively, and polish the cut surfaces for standby use;

[0076] Step S4: preparing diamagnetic materials, superconducting materials and thermal insulation materials;

[0077] Step S5: Paste the anti-magnetic material on the cut surface of the triangular magnetizer 2 in step S3, align the periphery, paste the cut surface of the triangular main magnet 1 in step S3 on the surface of the anti-magnetic material, align the periphery, and restore the main magnet 1, the anti-magnetic layer 3 and the magnetizer 2 to a cube after combination;

[0078] Step S6: Paste the superconducting material around the cube formed in step S5 in sequence, without sealing it from top to bottom;

[0079] Step S7: magnetizing the cube in a magnetizing direction on a magnetizing machine, sealing the lower end of the cube with a shielding sheet, and leaving the upper end open;

[0080] Step S8: Brush or spray the heat insulation material evenly on the whole, and evenly brush the heat insulation material on the whole cube, and coat or spray the surface with dry noise. After the production is completed, a monopole permanent magnet with only one end showing a magnetic field is obtained.

[0081] The first method for manufacturing a sintered monopole permanent magnet is as follows, comprising the following steps:

[0082] Step S10: Select the type and brand parameters of the main magnet 1, cut the blank magnetic material into a cube shape, and then cut it into two triangles from the diagonal line, and polish the cut surface for standby use;

[0083] Step S20: preparing superconducting materials and thermal insulation materials;

[0084] Step S30: Select the magnetizer 2 and process it into a cube, open a triangular groove in the middle of the magnetizer 2, apply a sintering agent on the cut surface of the magnetizer 2, and then embed the triangular main magnet 1 into the triangular groove of the magnetizer 2;

[0085] Step S40: Place the magnet in a sintering furnace and sinter at a suitable temperature. After sintering, take it out and cool it. The main magnet 1 and the magnetizer 2 have formed a square whole. Polish the surface for standby use.

[0086] Step S50: Selecting side sealing plates and bottom sealing plates made of superconducting materials, and pasting them on the side surfaces and bottom surfaces of the cube respectively;

[0087] Step S60: magnetizing the cube in a magnetizing direction on a magnetizing machine;

[0088] Step S70: evenly apply the heat-insulating material to the entire cube, and coat or spray the surface with a dry noise, and the production of the monopole permanent magnet is completed.

[0089] The second manufacturing method of sintered monopole permanent magnet is similar to the first manufacturing method, and only needs to replace the step S30 in the first manufacturing method with step S300: select the magnetizer 2 to be processed into a cube, open a triangular groove in the middle of the square magnetizer 2, apply sintering agent on the cut surface of the square magnetizer 2, cut off a corner of the hypotenuse of the triangular main magnet 1, fill the cut corner with the same size material as the magnetizer 2, and stick them together, and then embed the combined triangular main magnet 1 into the triangular groove of the magnetizer 2. The rest of the process is the same. In the attached Figure 8 With attached Fig. 9 The reference numeral "A" in the figure refers to the corner of the main magnet 1 where the magnetic conductive material is supplemented after being cut off.

[0090] Preferably, no matter the manufacturing method of sintered monopole permanent magnet or bonded permanent magnet, each bonding surface must be cleaned.
