Description

Electromagnetic Wave induction generator

The present invention relates to an electromagnetic induction generator, and more particularly to a magnetic field induction generator.

In general, electromagnetic waves are energy generated from the flow of electricity and magnetism, also called radio waves. In other words, when vibration occurs while electricity flows, an electric field and a magnetic field are generated at the same time, and the wave generated by changing periodically is called an electromagnetic wave. These electromagnetic waves are always around us.

Electromagnetic waves can be classified into electric fields generated by voltage and magnetic fields generated by electric current, and are generated from everything that uses electricity, such as transmission / distribution lines and electrical appliances in use around us.

Electric fields or electric fields are generated in a straight line vertically from the source and are easily removed or weakened by trees, buildings, or human skin. Magnetic field or magnetic field has a characteristic that it is formed in a circle around the source, so it is not easily removed or weakened by any object or material.

When electromagnetic waves are classified in order of high frequency, gamma rays, X-rays, ultraviolet rays, visible rays (light), infrared rays, radio waves (ultra high frequency, high frequency, low frequency, ultra low frequency) and the like.

The ultra-low frequency and the low frequency have a high electric field and a magnetic field, and when exposed to the human body for a long time, the body temperature change and the biorhythm are broken and it is likely to develop into a disease.

Examples of electromagnetic waves around us include effective isotropically radiated power from nearby base stations, magnetic fields around high-voltage power plants or substations, and strong electromagnetic interference from high-power communication / electric systems. This can be.

There is a way to ensure stability from these electromagnetic environment problems. In addition, a situation in which a method of reproducing harmful electromagnetic waves into electrical energy is drawing attention.

Accordingly, the present invention provides an apparatus for securing electrical energy from an electromagnetic environment.

Using the electromagnetic wave induction generator according to the present invention can reduce the effect on the human body by the electromagnetic wave, there is an effect that can secure the renewable energy using electromagnetic waves harmful to the space.

Figure 2 is another embodiment of the winding shape for receiving power of the electromagnetic wave induction generator according to the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, as a state diagram of an electromagnetic wave induction generator 10 according to the present invention, an electromagnetic wave derivative material 11 is coupled to a power receiving winding 12 so that an alternating current is induced by a spatial electromagnetic wave. It is characterized in that it comprises a rectifier circuit 13 for rectifying the induced alternating current generated in the winding.

Referring to Figure 2, as another embodiment of the winding shape for receiving the power of the electromagnetic wave generator according to the present invention, a loop type 12a, a solenoid type 12b, a square spiral type 12c may be mentioned.

The winding shape is not specified but a shape through which electromagnetic wave induced current can flow, and may be a combination of the shapes.

The electromagnetic induction generator according to the present invention is characterized in that the electromagnetic wave inducing material 11 is formed into a flat sheet, and the windings 12 for receiving power are inserted between the genital sheets.

The sheet form may have an electromagnetic wave inducing material in the form of a film or a thin film.

Or, it may be made of a fabric fabric, knitted fabric, non-woven fabric, or by coating an electromagnetic wave inducing material on the fabric.

Alternatively, the fiber yarn may be coated with an electromagnetic wave inducing material to form a woven fabric, a knitted fabric, or a nonwoven fabric.

When the electromagnetic wave is irradiated onto the power receiving winding combined with the electromagnetic induction material, an induced current flows due to the electromagnetic induction phenomenon.

Alternatively, it is another preferred embodiment to coat or coat the electromagnetic wave inducing material on the power receiving winding.

Alternatively, the power receiving winding is buried in the electromagnetic wave inducing material in another embodiment.

Alternatively, an electromagnetic wave induction generator formed by blocking the electromagnetic wave inducing material and winding a winding for receiving power on the block.

The electromagnetic wave inducing material is a magnetic material, and refers to a material having a property of adhering to a magnet.

In a magnetic body, each atom acts like a magnet, but these atoms are irregularly aligned in the absence of an external magnetic field, and thus have no magnet-like effect. But when you bring a magnet from the outside, the atoms will stick to the magnet because they try to align in the direction of the external magnetic field.

When a strong magnetic field is applied to these magnetic bodies, these magnetic zones are aligned to have a strong magnetization degree.

In general, it refers to an area in which the direction of magnetization is divided differently inside the ferromagnetic material and is also called a magnetic domain. In general, crystalline materials have electrons with magnetic properties in the crystal lattice. Ferromagnetic materials have the property that these magnetic charges interact with each other to align in the same direction. In nature, this self-alignment works with the thermodynamic tendency to maintain disorder, resulting in an overall disordered distribution but partially aligned. The partially aligned regions are called magnetic zones, and the boundaries between magnetic zones are called magnetic domain walls.

In the magnetic zone, if the magnetic field is enlarged, the magnetization in each magnetic zone rotates and aligns in the direction of the magnetic field, and the magnetization reaches the maximum value.

Iron loss consists of hysteresis loss and eddy current loss.

In the low frequency region, hysteresis loss due to the movement of the wall is dominant, but in the high frequency region, the eddy current loss is dominant.

Magnetic loss of magnetic material is classified into hysteresis loss, eddy current loss and residual loss. Hysteresis is a loss caused by the irreversible change of domain walls by inclusions or defects in the process of magnetization and demagnetization. Residual loss is the loss due to magnetic relaxation and magnetic resonance with frequency. In other words, as the frequency increases, the loss caused by the movement of the magnetic wall and the rotation of the magnetization is not smooth.

The electromagnetic induction generator according to the present invention is characterized by using a soft magnetic material that can minimize the loss.

Magnetic materials are classified into hard magnetic materials and soft magnetic materials according to their magnetic history characteristics and application fields. Herein, the soft magnetic material means a property of easy magnetization reversal in the range of 0.005 to several Oe of coercivity, which is the strength of magnetization required for diamagnetization.

Soft magnetic materials include ferritic and metal alloy materials and amorphous materials, amorphous wires, nanocrystalline materials, soft magnetic composite materials, and the like.

The soft magnetic material has a high permeability and a low coercive force, and is composed of domains and domain walls, which are aligned with the axis of easy magnetization when no magnetic field is applied from the outside. However, when the magnetic field applied from the outside is applied in a direction perpendicular to the direction of the easy axis of magnetization, the directions of the magnetic domains are different from each other.

When a magnetic field is applied in a direction perpendicular to the easy axis, there is no movement of the magnetic walls and only rotation of the magnetic domains. However, when the magnetic field is applied in parallel with the easy axis direction, there is no rotation of the magnetic domains and only the movement of the magnetic walls occurs.

Permeability is expressed as the change in magnetization with the applied magnetic field. Therefore, the ultra-high magnetic permeability means a change in the magnetization amount when a small alternating magnetic field is applied to the magnetic material. The magnetization difficulty axis produces a change in magnetization according to the alternating magnetic field, but the magnetization axis does not change in magnetization amount. Therefore, the ultra-high frequency AC permeability represents the amount of change in magnetization according to the externally applied magnetic field for the difficult magnetization axis.

Irradiating the ferromagnetic material with electromagnetic waves causes precessional motion of magnetization and absorbs electromagnetic waves of the natural frequency of the material. That is, magnetic resonance absorption occurs. Therefore, the magnetic moment cannot follow the magnetic field when the applied alternating magnetic field is larger than the resonance frequency. This characteristic is shown in the permeability characteristics with respect to frequency, and the resonance frequency is defined as the resonance frequency. This resonant frequency depends on the amount of saturation magnetization, anisotropy constant and shape anisotropy constant of the ferromagnetic material.

The ultra-high permeability characteristics include ferromagnetic resonance phenomena and can only be used below the ferromagnetic resonance frequency when ultra-high permeability materials are used in electromagnetic induction generators. Therefore, it is necessary to shift the resonant frequency into the ultra high frequency region.

The resonant frequency and initial permeability are proportional to the saturation magnetization. Therefore, when an uniaxial anisotropic material is used, the anisotropic magnetic field can be increased.

Magnetic materials with a large amount of magnetization have metallic properties. When the metallic magnetic material is used in the ultra-high frequency band, the loss effect due to the eddy current increases. Therefore, in order to use a magnetic material having a large magnetization amount in an electromagnetic induction generator, it is necessary to increase the conductive resistance to reduce the loss caused by the eddy current.

Therefore, the electromagnetic wave induction material according to the present invention increases the eddy current loss due to the effect of alternating (repetitive) magnetic fields due to the high frequency, but in order to reduce this, the magnetic material is made a fine powder, the surface is covered with an insulating film, and formed into a binder. It is characterized by using a magnetic core material.

As an embodiment of the shaping method of the electromagnetic wave inducing material, the magnetic core material is characterized by using a pure iron green core, a permalloy green core, a carbonyl green core, a sendust green core, 6.5% silicon steel sheet, amorphous (amorphous material).

Since hysteresis loss is proportional to the operating frequency, it is predominantly in the low frequency region below 1 kHz.

In addition, the eddy current loss here means the energy loss mainly caused by the eddy current which flows in a soft magnetic material.

Since the eddy current loss is proportional to the square of the operating frequency, it is mainly dominant in the high frequency region of 1 kHz or more.

Therefore, the soft magnetic material in the magnetic material is required to have a magnetic property that reduces the occurrence of iron loss. In order to realize this, it is necessary to increase the magnetic permeability, the saturation magnetic flux density and the electrical resistivity of the soft magnetic material, and to reduce the coercive force of the soft magnetic material.

As another embodiment of the electromagnetic wave inducing material of the present invention, a plurality of composite magnetic particles, the composite magnetic particles are a metal magnetic particles and a glass insulating film covering the surface thereof. The magnetic metal particles are Fe, Fe-Si alloy, Fe-Al alloy, Fe-N alloy, Fe-Ni alloy, Fe-C alloy, Fe-B alloy, Fe-Co alloy, Fe- It is formed of a P-based alloy, a Fe-Ni-Co-based alloy, a Fe-Cr-based alloy or a Fe-Al-Si-based alloy.

In order to reduce the hysteresis loss in the core loss of the magnetic core, the coercive force may be reduced by removing the deformation or dislocation in the magnetic metal particles to facilitate the movement of the magnetic wall.

The soft magnetic material is a soft magnetic material containing the magnetic metal particles and composite magnetic particles having an insulating coating covering the magnetic metal particles, wherein the insulating coating is made of phosphoric acid, Fe, Al, Si, Mn, Ti, Zr. , Zn and at least one atom selected from the group consisting of silicone resins. The atomic ratio of Fe contained in the contact surface of the insulating film which contacts a metal magnetic particle is larger than the atomic ratio of Fe contained in the surface of an insulating film. The atomic ratio of the at least one atom contained in the contact surface of the insulating film in contact with the magnetic metal particles is smaller than the atomic ratio of the at least one atom contained in the surface of the insulating film.

In the soft magnetic material, preferably, the insulating coating includes a first insulating coating covering the metal magnetic particles and a second insulating coating covering the first insulating coating.

The first insulating film contains phosphoric acid and Fe, and the second insulating film contains phosphoric acid and the at least one atom.

In the soft magnetic material, preferably, the composite magnetic particles further have a coating containing Si exhibiting insulation covering the surface of the insulating coating. This is because insulation between the magnetic metal particles is ensured by a film containing Si.

Therefore, when forming the electromagnetic wave inducing material as the soft magnetic material, it is possible to reduce the iron loss of the magnetic core.

In addition, when the electromagnetic wave is irradiated to the electromagnetic wave inducing material composed of a soft magnetic material having a low coercive force is characterized in that the induced current occurs.
