Description

[0001] Magnet generator and generating method [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnet generator and a power generation method using the magnet generator. More particularly, the present invention relates to a magnet generator capable of producing electric energy using magnetic energy and a power generation method using the same.

Electricity is used as a major energy source in the industrial society, but due to the depletion of fossil energy, investment and development are rapidly progressing in various alternative power generation facilities such as solar power generation, wind power generation, and tidal power generation.

Electricity generated from a power generation facility is supplied to household and industrial devices or products requiring a relatively large amount of electric power through a power cable, and is used as an energy source. However, electric appliances such as small-sized household appliances and household goods, Most of the products required are equipped with a secondary battery such as a primary battery or a lithium ion battery and are used as a power source.

However, since the battery is limited to the use time, the battery must be recharged when the power is discharged. However, since the battery can not be charged while it is in motion or outdoors, the battery can not be used at the time of discharging. In order to solve these problems, various self-generating devices have recently been developed so as to be able to charge the necessary power source in an emergency.

Generally, a generator is a device that receives mechanical energy from an external power source to convert it into electric energy. As well known as the external power source, a turbine turbine, an electric motor, a gasoline engine, or the like can be used. As a method of generating electric energy using the external power source, there are a hydroelectric power generation using a difference in potential energy of water and a power generation using natural power such as wind power using wind power. In addition, And thermal power generation and nuclear power generation that utilize natural resources such as natural gas and electricity to generate electricity by artificial methods. In addition, solar power generation using solar heat has been actively studied recently.

In the generator using the external power source as described above, the basic principle of power generation is based on the relative relationship between the electrons and the magnetic field in the conductor. That is, when the conductor breaks the magnetic flux, a voltage is induced across the conductor, Current flows through the voltage. At this time, the magnitude of the induced voltage E is given by E = Blv, which is the product of the magnetic flux density B, the length l of the conductor continuing its magnetization and the moving speed v of the conductor.

However, the above-described power generation mechanism necessarily requires an external power source, and power generation can not be continued unless mechanical energy is continuously supplied from an external power source. In addition, there is a problem that energy conversion efficiency of power generation is deteriorated due to energy loss due to friction generated when mechanical energy of an external power source used for power generation is converted into electrical energy through a generator.

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

The embodiments of the present invention are described in order to more fully explain the present invention to those skilled in the art, and the following embodiments may be modified into various other forms, It is not limited to the embodiment. Rather, these embodiments are provided so that this disclosure will be more thorough and complete, and will fully convey the concept of the invention to those skilled in the art. In the drawings, the thickness and size of each layer are exaggerated for convenience and clarity of explanation.

1 to 3 are conceptual diagrams showing a magnet generator 100 according to some embodiments of the present invention.

1 to 3, a magnet generator 100 according to some embodiments of the present invention may largely include a stator 10, a rotor 20, and a control unit 30.

For example, the stator 10 may be a generally cylindrical structure in which coils 12 wound around the core 11 are installed.

For example, the rotor 20 may include a permanent magnet (not shown) which is rotatably installed in the stator 10 and is capable of generating current in the coils 12 by using magnetic energy during rotation 21 may be provided.

In the control mode, for example, the control unit 30 applies a magnetization control signal to the coil 12 so that the core 11 becomes an electromagnet and the rotor 20 can be forcibly rotated by the force of a magnetic force A circuit board, a processor, a microprocessor, a central processing unit, an arithmetic unit, a program form, and the like, capable of collecting electric energy generated in the coils 12 by rotation of the rotor 20 in a power generation mode The storage device may be an electronic device including one or more of the storage devices recorded with the recording device.

Here, the magnetic force of the permanent magnet 21 is not permanently preserved. The present invention converts magnetic force energy into electric energy. For example, the magnetic force may be lost after 5 to 10 years.

Although not shown in the drawings, a cooling device for retaining magnetic force, such as a blower, a blowing hole, and a flow path, is provided in order to prevent the temperature of the permanent magnet 21 from rising excessively to maintain the magnetic force of the permanent magnet 21 as much as possible Can be installed.

More specifically, for example, as shown in FIGS. 1 to 3, the number of the permanent magnets 21 mounted on the outer surface of the rotor 20 on the basis of one point of the rotation axis S And the number of the coils 12 of the stator 10 corresponding thereto. The term irrational number refers to an infinite prime number that does not circulate when expressed as a prime number, and an infinite prime number can be a cyclic prime number as a prime number.

For example, as shown in FIGS. 1 to 3, the number of the permanent magnets 21 mounted on the outer surface of the rotor 20 is 12, , And the number of the coils of the stator 10 corresponding thereto may be eleven.

If the number of the permanent magnets 21 is divided by the number of the coils 12 of the stator 10 corresponding to the number of the permanent magnets 21, the number of the permanent magnets 21 may be 12/11.

2, in the control mode of the coil 12, the coil 12 of the stator 10 is connected to the corresponding surface of the rotor 20 corresponding to the permanent magnet 21, The polarities of the electromagnets formed are alternately arranged at N and S poles at specific times, and at least a part of the electromagnets may be formed such that N poles and N poles or S poles and S poles are adjacent to each other.

Therefore, as shown in FIG. 2, since the permanent magnets 21 do not correspond exactly to the positions of the coils 12 of the stator 10, the rotational forces are abruptly changed by attraction by the corresponding positions The rotation loss can be prevented, and the change in torque can be continuously increased little by little while rotating very smoothly. As a result, the number of revolutions can be greatly increased even with a small force.

Therefore, as shown in FIG. 1, when the rotor 20 is initially driven with a small force using the attraction force or the power of the motor, the control unit 30 The control unit 30 amplifies the rotation speed of the rotor 20 while performing the control mode so that the control unit 30 performs the power generation mode as shown in FIG. To collect the power of the coil 12 that is induced in accordance with the control signal. This control mode and the power generation mode can be continuously collected while repeating a very short time.

As a result, self-power generation can be achieved without consuming external power over a long period of time while consuming the magnetic energy of the permanent magnets 21. However, since the magnetic force of the permanent magnet 21 is not permanent as the name suggests, it has been confirmed from repeated experiments that the magnetic force of the permanent magnet 21 is consumed and the electric power production is decreased after a long period of time. Therefore, the present invention is not a permanent organ.

4 to 7, the magnet generator 200 according to some other embodiments of the present invention includes a fixed case 1, a front cover 2, a rear cover 3, A stator 10, a rotor 20, and a control unit 30. [

For example, the fixed case 1 has a housing space capable of protecting the stator 10 and the rotor 20 from external foreign substances or external force, and the stator 10 and the stator 10 are accommodated in the housing space. After the rotor 20 is assembled, the front cover 2 and the rear cover 3 are covered on the front and rear sides of the stationary case 1 to manufacture the product.

FIG. 8 is an exploded perspective view of the stator 10 of the magnet generator 200 of FIG. 4, and FIG. 9 is a perspective view of the coil module 14 of the magnet generator 200 of FIG.

More specifically, for example, as shown in FIGS. 8 and 9, the stator 10 is a generally cylindrical structure capable of accommodating the rotor 20 therein, and the core 11 ) Of a cylindrical shape, which is an insulating resin material, having openings (13a) formed on the front and rear sides thereof and a plurality of holes (H1) formed on the outer diametric surface, the coils (12) A core 13 and a coil base 15 made of an insulating resin material and detachably installed in the hole H1 of the fixed body 13 and surrounding the core 11, A coil module 14 including a coil 12 wound on the coil base 15 and a coil module 14 mounted on the opening 13a of the fixed body 13 and bearing the rotor 20 And a shaft supporting plate 16 for rotatably supporting the rotary shaft S of the rotary shaft. Here, the core 11 may include carbon steel or iron oxide containing a carbon component so as to be easily electropolished. Particularly, the core 11 may be made of carbon steel of various materials so as to minimize the eddy current and facilitate the magnetization.

9, each of the coil modules 14 is electrically connected to the outer surface of the fixed body 13 and to the coil base 15 by means of wires (not shown) The guide groove GH can be formed. The wire guide grooves GH may be formed in various shapes without being limited to the drawings, and various terminals and wiring layers other than wires may be used.

For example, the electric wire guide grooves GH are not limited to the drawings, but may be formed in the form of a horizontal line and a vertical line on the outer surface of the fixed body 13.

Therefore, a plurality of the coil modules 14 can be inserted into the holes H1 of the fixed body 13 to form a fixed structure. By using the shaft supporting plate 16, 20 can freely rotate.

11 is a perspective view showing a permanent magnet 21 of the magnet generator 200 of FIG. 10, and FIG. 14 is a perspective view of the permanent magnet 21 of the magnet generator 200 of FIG. 4 is a photograph showing an example of the magnet generator 200. Fig.

More specifically, for example, as shown in FIGS. 10, 11, and 14, the rotor 20 is rotatably installed inside the stator 10, and uses magnetic energy during rotation And a permanent magnet 21 capable of generating an electric current in the coils 12. The permanent magnet 21 is inserted into the fixed body 13 of the stator 10, A rotating body 22 in the form of a cylindrical insulative resin material having a plurality of grooves H2 formed on an outer surface of the shaft support plate 16 so as to be freely rotatable and rotatable, And a permanent magnet 21 inserted into the permanent magnet 21.

More specifically, for example, the coil-facing surface of the permanent magnet 21 may be formed with a spherical surface 21a to further narrow the distance from the coil 12. [

The number of the permanent magnets 21 installed on the outer circumferential surface of the rotor 20 relative to one point of the rotation axis S is set to be larger than the number of the permanent magnets 21 of the coils 12 of the stator 10, Divide by number can be irrational or infinite prime.

For example, the number of the permanent magnets 21 equally mounted on the outer surface of the rotor 20 is 12, and the number of the permanent magnets 21 of the coils of the stator 10 The number may be eleven.

The coil 12 of the stator 10 is arranged such that the polarities of the electromagnets formed on the corresponding surfaces of the rotor 20 corresponding to the permanent magnets 21 alternate between N poles and S poles And at least a part of them may be arranged so that the N pole and the N pole or the S pole and the S pole are adjacent to each other. This arrangement can smoothly and continuously amplify the change in the rotation torque.

At least a part of the stator 10 or at least a part of the rotor 20 may be made of an insulating resin material so as to prevent the eddy current.

Particularly, in order to minimize the eddy current, for example, the fixed body 13 of the stator 10, the rotating body 22 of the rotor 20, the coil base 15 and the like are made of an insulating resin material As shown in FIG. For example, various poly-series synthetic resins such as acrylic and plastic can be applied.

Therefore, as shown in FIG. 7, since the permanent magnets 21 do not correspond exactly to the positions of the coils 12 of the stator 10, the rotational forces are abruptly changed due to attraction by the corresponding positions The rotation loss can be prevented, and the change in torque can be continuously increased little by little while rotating very smoothly. As a result, the number of revolutions can be greatly increased even with a small force.

12 is a circuit diagram showing the control unit 30 of the magnet generator 200 of FIG.

12, the control unit 30 may include a relay control unit 31 for controlling the coils 12 of the stator 10 at the same time.

In addition, although not shown, the control unit 30 may select at least one of an inverter, a converter, and a rectifier so as to convert the generated primary AC into DC and convert the converted DC into a secondary AC .

In the control mode, the control unit 30 applies a magnetizing control signal to the coil 12 so that the core 11 becomes an electromagnet and the rotor 20 can be forcibly rotated by the force of a magnetic force, A substrate, a circuit board, a processor, a microprocessor, a central processing unit, a computing unit, a storage unit (not shown) in the form of a program capable of collecting electric energy generated in the coils 12 by the rotation of the rotor 20, Or an electronic device including any one or more of the devices.

13 is a flowchart showing a control method using a magnet generator according to some embodiments of the present invention.

1 to 13, a control method using a magnet generator according to some embodiments of the present invention includes an initial rotation (rotation) of rotating the rotor 20 for the first time using an external power such as a start motor or a pulling force, The control unit 30 controls the rotor 20 so that the rotor 20 is rotated by the initial power to generate the initial power from the rotor 20, A power generation step S4 for generating electric energy by performing the power generation mode and a control mode execution step S3 for controlling the power generation mode, And repeating the step S4 repeatedly to increase the number of rotations of the rotor at the reference rotation speed.

Here, if the number of revolutions is too slow, inertial force can not be sufficiently obtained, and if it is too fast, various kinds of heat generation and parts wear may occur mechanically.

Therefore, in the simulation and repetitive experimental results, preferably in the step of amplifying the number of revolutions (S5), the reference rotational speed may be 3000 RPM to 9000 RPM.

13, the power production step S4 includes a DC converting step S41 for converting the produced primary AC into DC, and an AC converting step S41 for converting the converted DC into a desired secondary AC And a conversion step S42.

15 is a photograph of a magnet generator according to some alternative embodiments of the present invention.

As shown in FIG. 15, as a result of experimenting with an actual product, it was possible to produce electric power of 10 kilowatts or more per hour while consuming magnetic energy using the initial driving force. However, the results of these experiments are derived only from limited time and limited goods, and may affect the quality of the permanent magnet, the number of turns of the coil, and the material of the product.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
