Description

Automatic Rotating Device Using Diamagnetic Material, Magnet and Electromagnet

The present invention relates to an automatic rotation device using a diamagnetic substance, a magnet, and an electromagnet, and more particularly, shields the outside of the magnets of the rotor and the stator with a magnetic substance (a magnetic field flows through the magnetic substance so that the magnetic field does not act on a nearby space). install; A diamagnetic substance is installed between the magnets where the attractive force acts to weaken the attractive force and rotate it using a repulsive force; By making the magnetic field of the rotating magnet and the diamagnet work the repulsive force; Inducing the force of the diamagnet's motion into electricity in the coil; The electricity generated in the coil can be used as rotational energy by using the attraction and repulsion of the magnet and the attraction and repulsion of the electromagnet configured to increase the rotational force with a three-phase motor or brushless [B.L.D.C] motor.

In general, a motor, which is a rotating device, is a rotating device that converts electrical energy into mechanical energy, and is divided into a DC motor driven by a DC power source and an AC motor driven by an AC power source.

Among them, the DC motor is composed of a stator made of permanent magnets and a rotor that rotates by the stator and attractive and repulsive forces, and the rotor is fixed to and installed on a rotating shaft to make rotation, It is composed of a coil that is wound around the iron core so that the iron core has an electromagnet property by the applied current, and a commutator that periodically changes the direction of the current and supplies it to the coil.

In addition, the opposite structure is a DC motor, which has a rotor having a permanent magnet, a stator generating a rotor field with respect to the permanent magnet of the rotor, and a means for exciting the stator. The rotor is sequentially excited to generate a rotor field, and the rotor rotates by repeating attractive and repulsive forces of permanent magnets disposed in the rotor with respect to this rotor field.

On the other hand, shielding the magnetic field of a magnet is to reduce the working space range of the magnetic field with a ferromagnetic material, and to reduce the spatial range in which the magnetic field acts as the magnetic field flows to the ferromagnetic shielding material.

At this time, the strength of the magnetic field and the volume of the ferromagnetic material act in inverse proportion to the spatial range of the magnetic field. If the volume of the shield is smaller than the strength of the magnetic field, the shielding efficiency is lowered.

On the other hand, a diamagnetic material is an object made of a material that generates the same magnetic pole when a magnet approaches it, unlike a magnetic material.

Most of these conventional DC motors consist of a rotor composed of a permanent magnet or an armature made of an iron core, coil, etc., and a stator formed around the rotor and made of an armature or permanent magnet. When current is supplied, the rotor As a rotating device that rotates to obtain power, since the permanent magnet is provided in a limited standard, the output is also limited.

For example, in order to lower the input electric energy, the power consumption must be lowered. To do so, the resistance (impedance) of the motor must be lowered in order to flow a lot of current at a low voltage. If the number of windings is reduced, the resistance value can be lowered.

However, if the number of windings of the coil wound around the iron core is lowered as described above, the intensity of the magnetic force generated here is weakened and the output is weakened accordingly.

Conversely, if the voltage is increased to increase the flow of current, the power consumption also increases. If the number of windings of the coil is increased, the resistance increases and the strength of the magnetic force generated in the coil becomes stronger, but the input electrical energy must be increased, so the power consumption is correspondingly increased. it rises

If the magnets are configured as a stator, the magnets may be arranged in two or more layers to increase the strength of the magnetic force to increase the output of the DC motor. However, in this structure, the load between the stator and the rotor is Since it is large, there is a problem in that a large initial current value is required.

On the other hand, when the stator and the rotor are provided with only the magnet, when the repulsive force of the same pole meets each other, it is pushed away and cannot be approached, and in the case of the attractive force of the different pole, it is not separated, so the pure magnet only device has a problem that makes it difficult to rotate. .

In addition, when the magnetic field on the side where the stator and the rotor approach each other based on the direction of rotation is shielded, at some point, the initial repulsive force rapidly increases in the direction of the opposite magnetic pole, making it difficult to rotate.

In order to achieve the above object, the present invention removes the repulsive force by reducing the magnetic field generated from the same magnetic pole by installing ferromagnetic shielding means on the stator and the rotor, that is, when the shielded rotor approaches the shielded stator, As a solution to overcome this, since repulsive force for reverse rotation does not occur up to a predetermined part of the point where the rotation direction is switched by approaching, and repulsive force is generated toward the center of rotation in a small area from the approached part to the turning point. ; Magnets were arranged in a structure in which attractive force acts on the angle of the reverse rotational repulsion so that the attractive force and the repulsive force cancel each other so that the sum of the pushing and pulling forces becomes zero.

Therefore, the rotational force was generated in other sections except for the section where the force is offset, and it is possible to configure the above-described attractive force and repulsive force in reverse, and the rotation section and the offset section are complemented with each other so that all sections generate rotation.

In addition, rotating magnets are alternately arranged, electricity is generated by the repulsive force generated by the magnet and the diamagnetic material, and a motor is used as the power source to reinforce the rotational force and accelerate the rotational speed.

Therefore, the attractive and repulsive force of the magnet shielded from the motor rotational force of the electromagnet, which can obtain rotational force with the electric energy generated by itself, is included in the rotational force, and accelerated so that a stronger output is generated.

As described above, the automatic rotation device using the diamagnetic material, magnet, and electromagnet of the present invention generates the following effects.

1. Strong rotational force generated by the fusion of attraction and repulsion generated between the shielded stator and rotor, repulsive force of diamagnets, and rotational force by electromagnets and electromagnets, generates energy as an automatic rotating device and can be used as clean energy. there is.

2. It is possible to increase the speed and power with the energy of the initial magnet, so it is possible to increase the power of the electromagnet due to the increase in the rotational speed and the power generation of the diamagnetic material, enabling the use of large-capacity alternative energy.

3. It is a device that does not cause environmental pollution because it is a device that generates rotational energy using the repulsive force of diamagnetic substances and magnets and the shielding of magnets.

4. Since manpower and repulsive force are used together, the reduction of magnetic force is minimized and semi-permanent use is possible.

5. It is convenient because it can be used as an independent power generation device in mountainous or island areas by supplying energy with self-generated power.

The configuration of the present invention will be described in detail based on the drawings presented in FIGS. 1 to 7.

First of all, I would like to explain the working relationship between diamagnets and magnetism.

When a general ferromagnetic material comes into contact with a magnetic field of magnetic force, it becomes the opposite pole of the contacted magnet and sticks to it as a magnet. On the other hand, when a diamagnetic material comes into contact with a magnetic field of magnetic force, the opposite side forms the same pole as the magnet, and the repulsive force that pushes it out of the magnetic field refers to the object on which it acts.

That is, as shown in FIGS. 1, 2, and 3, when the magnet 02 approaches and the magnetic field approaches the diamagnetic material 01, the opposite surface of the diamagnetic material 01 forms the same pole as the magnetic pole. A repulsive force is generated; A repulsive force is generated between the electromagnet 61 and the diamagnetic material 01 as in the above case.

That is, in FIG. 1, the shielded magnet 02 starts to have the same magnetic pole as the diamagnetic material 01 at #2 and has the highest magnetic pole at #3; Figure 2 shows the movement relationship between the general magnet 02 and the opposite magnet 51 and the diamagnetic body 01, and Figure 3 shows the movement relationship between the electromagnet 61 and the diamagnetic body 01. , interpretation is convenient if the color body is understood as a magnetic pole.

At this time, among the diamagnetic materials 01, a material having the strongest diamagnetic ability currently known is bismuth.

Therefore, as shown in FIG. 4, making the bismuth powder 41 linearly reciprocate within the space of the ceramic cylinder 32 inside the power generation coil 31; The purpose is to make the bismuth powder 41 reciprocate in a straight line by installing the shielding repulsive magnets 33 and the repulsive force counteracting magnets 51 alternately, and to generate electric energy in the power generation coil 31. As the quantity moves, the power generation increases.

Then, in order to induce rotational motion using the attractive force of the shielded magnet, the shielding is called shielding that 1/2 of the outer surface of the magnet is surrounded by a ferromagnetic material. use manpower; A case in which the rotating plate 93 is rotated using the shield rotating magnet 22 and the auxiliary side magnet 13 and the side corresponding magnet 14 acting on the repulsive force and the case in which the opposite magnetic pole is used will be described.

A side auxiliary magnet 13 is installed on one side of the side of the shielding fixed magnet 11 installed on the fixed body 91; A side corresponding magnet 14 is installed on the other side of the shielding fixed magnet 11.

At this time, the magnetic poles of the shielding fixed magnet 11, the side auxiliary magnet 13, and the side corresponding magnet 14 are opposite magnetic poles; The magnets are shielded; Based on the line connecting the center of the shielded magnet 11 and the center of rotation, the shielded direction of the magnet is installed in the opposite direction as shown, so that the shielded rotating magnet 22 and the shielded magnet 11 act by attraction; A repulsive force acts between the shield rotating magnet 22, the side auxiliary magnet 13, and the side corresponding magnet 14; The shielding effect is that the magnets of the stator and the rotor acting with attractive force do not act when the rotor passes the stator, and the repulsive force acts for the magnets acting repulsive force when the rotor passes the stator; A diamagnetic material (01) is installed between the shielding stationary magnet (11) and the shielding rotating magnet (22) at the point where the most attractive force acts and at the midpoint between them; A repulsive force acts between the magnets facing each other between the diamagnetic material 01, the shielding stationary magnet 11, and the shielding rotating magnet 22; The attractive force between the shielding stationary magnet 11 and the shielding rotating magnet 22 is weakened; A repulsive force acts between the shield rotating magnet 22, the side auxiliary magnet 13, and the side corresponding magnet 14; If the repulsive force acting between the shielded rotating magnet 22, the side auxiliary magnet 13, and the side corresponding magnet 14 is greater than the magnitude of the attractive force between the shielded fixed magnet 11 and the shielded rotating magnet 22, the rotating plate 93 makes it rotate.

On the other hand, a side auxiliary magnet 53 is installed on one side of the shielding fixed magnet 55 installed on the fixed body 91; A side-corresponding magnet 54 is installed on the other side of the shielding fixed magnet 55; At this time, the magnetic poles of the shielding fixed magnet 55, the side auxiliary magnet 53, and the side corresponding magnet 54 are installed in reverse; Based on the line connecting the center of the shielded magnet 55 and the center of rotation, the direction of shielding is reversed, and the magnetic poles of the corresponding surfaces of the shielded rotating magnet 52 and the shielded magnet 55 installed on the rotating plate 93 are meet the same; A repulsive force acts between the two magnets.

Subsequently, an attractive force acts between the shield rotating magnet 52, the side auxiliary magnet 53, and the side corresponding magnet 54; A diamagnetic material 01 is installed between the shield rotating magnet 52, the side auxiliary magnet 53, and the side corresponding magnet 54, respectively; weakening the attractive force between the shield rotating magnet 52, the side auxiliary magnet 53, and the side counterpart magnet 54; When the repulsive force generated between the shield rotating magnet 52 and the shield fixed magnet 55 is greater than the attractive force, the rotating plate 91 rotates.

Subsequently, when installing the case of attraction and repulsive force generated between the stator and the rotor as shown in FIG. 7, if multiple installations; The force of attraction and repulsion cancels out, so the pushing and pulling force is zero; Rotational force is generated in the section except for the offset portion, and if the portion with zero pushing and pulling force and the portion with strong rotational force are overlapped, rotational force is generated in all sections of the rotating shaft.

On the other hand, bismuth powder 41 is placed inside the space of the ceramic cylindrical body 32 inside the power generation coil 31; A plurality of power generation coils 31 are installed in the fixed body 91 to have a predetermined pitch and pitch circle diameter.

Subsequently, it is installed on the side of the rotating plate 93 to be the same as the diameter of the pitch circle of the power generation coil 31 installed in the repulsive force test magnet 33; A repulsive force-responding magnet 51 is installed on the opposite side of the rotating plate 93; As shown in FIG. 4, the installation positions of the repulsive force test magnet 33 and the repulsive force corresponding magnet 51 are staggered, and when the rotating plate 93 rotates, the bismuth powder 41 is installed inside the power generation coil 31 rectilinear reciprocating motion within the space of the ceramic cylinder 32; Electric energy is generated in the power generation coil (31).

At this time, the configuration of the present invention is completed by installing a motor operated by the generated electric energy connected to the rotating shaft to increase the rotational force and to have acceleration and output.

Next, the working state of the present invention will be described in detail based on the drawings presented in FIGS. 1 to 7.

In general, in order to rotate a motor using a magnet, it is most important that the pole of the electromagnet 61 is changed according to the position of the magnet.

This is for the purpose of uniformity of rotational force, and even in the case of the present invention, the uniformity of rotational force was completed by making an electromagnet with self-generated electricity and accelerating the rotational force with a motor.

In particular, by using the diamagnetic material (01) in the central position where the attractive force acts to weaken the mutual attractive force, while strengthening the mutual repulsive force, it is possible to rotate with only the attractive and repulsive force of the magnet without inputting electrical energy from the outside, which is It is not against the law of conservation of energy that the permanent engine of the first kind is impossible due to general enthalpy and entropy changes, but rather, it was found a way to rotate using the energy of attraction and repulsion of magnets. It is true that the value of enthalpy or entropy has nothing to do with the law of conservation of energy because it is immutable.

Describing the rotatable fact in detail, the unshielded surface of the shielded rotating magnet 22 faces the shielded fixed magnet 11 and approaches by mutual attraction; The center of the shielded magnet 11 and the shielded rotating magnet 22 are on the same axis, and when the inner part where the shielded magnet 11 is installed and the outer part installed in the shielded magnet 22 come closest, the force of attraction is strong. will do; Until the closest approach, the shielded rotating magnet 22, the side auxiliary magnet 13, and the side corresponding magnet 14 face each other so that repulsive force is not generated; a repulsive force in which a repulsive force occurs just before the closest approach; The diamagnetic material 01 installed between the shielded rotating magnet 22 and the shielded stator 11 combines the repulsive force, and at this point, the pushing and pulling force is zeroed out by canceling the attractive force generated from the two rotors and the stator.

Subsequently, after passing this point, the magnets to which the attractive force acts are shielded, and the magnetic field flows along the shielded ferromagnetic material, so that the unshielded side faces between the magnets where the attractive force does not act and the repulsive force acts, so that the repulsive force This occurs and rotates.

On the other hand, between the shielded rotating magnet 52 and the shielded fixed magnet 55, poles having the same repulsive force are opposed to generate a repulsive force, but the shielded surfaces are opposed, so that the outer side of the shielded rotating magnet 52 and the shielded fixed magnet A repulsive force occurs just before the installation inner side of (55) approaches the closest; At this time, the unshielded side of the shielded rotating magnet 52, the side auxiliary magnet 53, and the side corresponding magnet 54 is opposed to generate attraction; The diamagnetic material 01 installed between each of the shield rotating magnet 52, the side auxiliary magnet 53, and the side counter magnet 54 generates a repulsive force; At this point, where the magnets are most closely approached, the generated repulsive force and attractive force are offset, so that the pushing and pulling force is zero.

Subsequently, after passing this point, the magnets to which the attractive force acts are shielded, and the magnetic field flows along the shielded ferromagnetic material, so that the unshielded side faces between the magnets where the attractive force does not act and the repulsive force acts, so that the repulsive force This occurs and rotates.

Then, based on a point where the pushing and pulling force in the two cases described above is zeroed, if the zero point of the magnets centered on attraction and the point of zero point of magnets centered on repulsion are installed staggered without overlapping, The rotating shaft receives rotational force over the entire 360 degree section.

On the other hand, if the rotating plate 93 rotates as described above; A repulsive force is generated between the shield repulsive magnet 33 installed on one side of the rotating plate 93 and the bismuth powder 41 to move, and electricity is generated in the power generation coil 31 with this force; At this time, when the magnetic line of force 21 of the repulsive force-responding magnet 51 does not act on the bismuth powder 41, and the rotation continues and the magnetic force line 21 of the repulsive force-corresponding magnet 51 acts on the bismuth powder 41, the shielded repulsive magnet (33) does not act on the bismuth powder (41); At this time, the bismuth powder 41 moves to the opposite side; At this time, electric energy is generated in the power generation coil 31 by the movement of the bismuth powder 41.

Subsequently, the generated energy is supplied to the rotor 85 to rotate the stator 83 to accelerate the rotational force and induce a uniform rotational force at the same time.

Therefore, the present invention is a device capable of generating power with uniform power by inducing rotational force by using attraction and repulsion of magnets, and diamagnetism, and rotating a motor with self-generated electricity.

As described above, the present invention is a clean energy generating device using the repulsive force of a magnet, and the present invention is a necessary invention.
