Description

English Description DescriptionTitle of Invention : Method for electromagnetic induction to generate electricity with rotating magnetic shields Technical Field

[0001] The technical field of this invention is pertinent to electromagnetic generators that produce more electricity with less energy consumption. In this invention magnets, magnetic shields, and conductive metal materials are utilized.Background Art

[0002] Superconducting generator rotor electromagnetic shield filed in USPTO (application number: 11271578). This is a unitary bimetallic shield ring for a superconducting generator rotor includes coaxial inner and outer cylindrical portions. The outer cylindrical portion comprises a first metallic material for conducting eddy currents to dissipate energy, and defines an interior face. The inner cylindrical portion comprises a second metallic material for providing structural support to the outer cylindrical portion. The inner cylindrical portion is continuously metallurgically joined with the interior face of the outer cylindrical portion. The shield is made by first forming a substantially continuous weld between the inner and outer layers, and then machining the shield. The method and implementation of this invention are completely different from the claimed invention.Technical Problem

[0003] In the existing electromagnetic generators, the driving force, which can be water, wind, or various types of engines powered by fossil fuels, moves the magnet of the generator. In this case, due to Lenz's law, the driving force must expend a significant amount of energy to overcome the eddy currents of the Lenz's law and move the magnet, in which the movement of the generator's magnet causes a change in the magnetic field, resulting in electricity generation.

[0004] However, in this invention, by using a motor, the magnetic shields move in proximity to the stationary magnet, which in this case, there is no need to overcome the opposing forces created by the eddy currents of Lenz's law through kinetic energy.English Description Solution to Problem

[0005] For electromagnetic induction, a magnetic field is typically moved relative to a conductive metal so that with a change in the field within the conductive metal, from zero to a higher value, the process of generating electric current is carried out. In this invention, the magnetic field is directed into and out of the conductive metal by a shield so that there is no need to move the source of the field, namely the magnet, allowing the induction of electric current without energy consumption.

[0006] In this invention, directing the magnetic field into and out of the conductive metal is performed in several different configurations, which will be explained below.

[0007] In the first configuration, a ring magnet is used along with a ferromagnetic shield, which can be made of pure iron. The ferromagnetic shield is in the shape of the English letter "C" which surrounds the magnet according to the needed quantity.

[0008] With the movement of the ferromagnetic shields, a portion of the interior of the ring of the magnet is emptied of the magnetic field, and then, as the ferromagnetic shield passes through, the interior of the ring is once again filled with the field.

[0009] Since the magnetic field prefers to pass through the ferromagnetic shield, when the shield moves through the area that covers the magnet's surface, the magnetic field releases the ferromagnetic shield and penetrates into the inner conductive metal cylinder of the magnet and the conductive blocks above and blew the device and then attempts to generate energy by overcoming Lenz's law's opposing eddy-currents.

[0010] The ferromagnetic shields are connected to a shaft and this shaft is rotated by an electric motor at maximum speed so that the flux inside the metal cylinder and two conductive metal blocks changes from zero density to the density of the magnet's field as quickly as possible. This change generates electricity.

[0011] The energy consumed by this type of electric motor is only to overcome the friction of the shaft and air resistance. To prevent energy loss due to air resistance, a plastic cover can be placed between the shields so that the lateralEnglish Description edges of the shields do not interact with the air, allowing them to rotate more easily.

[0012] On the other hand, multiple shields can be placed around the magnet in several configurations. In one configuration, the shields can be placed next to each other using a semi-circular base of 180 degrees, which has slots embedded in it so that the shields fit into the slots and are mounted on the base. Then, a 180-degree steel arc is brought close to the center of the shields, and the arc is welded to the center of the back of the shields.

[0013] A vertical rod is attached to the center of the arc, and the top of the rod is threaded so that a non-magnetic piece (the connection clamp) can be screwed onto it. Then, the two arcs are screwed together at their ends to form a complete circle, surrounding the magnet with the shields. After the rotation of the shields in the device, the weight of the shield symmetrically falls onto the arc, and the arc restrains the centrifugal force of the shields.

[0014] Another method is using a base instead of the arc. A semi-circular base of 180 degrees with slots replaces the arc, where the shields are placed into the slots and mounted on the base. Then, the two semi-circular bases are screwed together at their ends to form a complete circle, surrounding the magnet with the shields. The base can be made of either metal or plastic. If the base is metal, the shields will be welded to it, and if the base is plastic, adhesive must be used. If the base is plastic, to withstand the heavy centrifugal force, it is better to use two bases above and below the shields.

[0015] The thinner the shields are, the more shields can be used to generate more electricity. However, the shields with two bases must be exactly in front of each other so that the magnetic field curve emanating from the magnet does not pass through the center of the magnet and enter the protective zone of the opposite shield.

[0016] Second configuration: Electromagnetic induction with a perforated superconducting shield

[0017] By utilizing two superconducting discs placed above and below the ring magnet, and with closed holes within them, the field can be directed into and outEnglish Description of the ring of the magnet by rotating the disc. In this case, electromagnetic induction occurs on the metal ring around the magnet as well as on the conductive cylinder inside the magnet. However, in this method, a single disc can also be used.

[0018] When the two superconducting discs rotate at high speed, the magnetic field inside and outside the ring of the magnet changes. Therefore, the holes of the two superconducting discs must always be aligned with each other to direct the magnet's field from the starting point to the correct point at the end. For this matter, the shaft hole can be made with a specific indentation, so that when the two discs are placed on the shaft, the holes are automatically aligned with each other.

[0019] The holes within the superconducting disc are arranged in such a way that one hole directs the magnet's field into the ring, while the side hole directs the magnet's field outside the ring and the more holes there are, the more energy will be generated in each round. An electrical insulator can also be placed around the magnet to prevent the currents generated in the conductor from penetrating the magnet, so as not weaken the magnet over time.

[0020] Another way, instead shields in the shape of the letter "C”, is to use two toothed ferromagnetic discs. These two discs are placed above and below the ring magnet, parallel to each other, and the teeth of the discs, while rotating, direct the magnet's field into and out of the ring of the magnet. This causes an electric current to be generated onto the conductive metal cylinder and the conductive ring.

[0021] The teeth must be aligned with each other to guide the field. To achieve this, the shaft holes of the discs can be made with a specific indentation, so that when the discs are installed on the shaft, the teeth automatically align, eliminating the need for manual adjustment.

[0022] When using the superconducting discs and the ferromagnetic discs, a conductive ring is installed around the magnet. In both cases, the current exits the device through the conductive ring. Additionally, the metal cylinder is connected to the conductive ring, allowing the current to transfer from the metalEnglish Description cylinder to the conductive ring. In this case, the conductive block does not become electrified.

[0023] If the edges of the teeth on the disc are slightly curved inward and have an edge, the field can be guided more effectively. In general, toothed discs are easier to manufacture but are not as effective at guiding the field as C-shaped shields.

[0024] By placing non-conductive components, such as plastic, between the teeth of the disc, air resistance can be reduced, allowing the disc to rotate with less energy loss. It is very important that the teeth of the two discs are perfectly aligned to shield the field.

[0025] To transfer power from the motor to the shaft, two methods can be used. In the first method, the motor should be screwed parallel to the device on two conductive blocks using plastic screws (to prevent electricity from leaking from the device to the motor) and rotate the shaft of the device using pulley and belt.

[0026] In the first method, the shaft of the motor is oriented upward and positioned beside the device, where the shaft of the device is also oriented upward. Pulleys are attached to both shafts, and a belt is looped around the pulleys so that as the shaft of the motor moves, the shaft of the device also rotates. Then, to secure the motor firmly, we connect it to a holder, which is screwed to the conductive blocks of the device.

[0027] The screw that fastens the motor's holder base to the conductive block should not be electrically conductive, as there is a risk of electricity of the device flowing into the motor and damaging it. Additionally, insulating materials should be wrapped around the motor to prevent arcing from the device to the motor due to the high voltage generated in the device, and to prevent the motor from burning out.

[0028] In the second method, in addition to using a belt and pulley, the motor can be connected to the device via coupling of the shaft. For this purpose, two couplings and a short non-conductive central shaft must be used to prevent electricity from flowing from the device to the motor through the shaft. One coupling connects the shaft of the motor to the non-conductive short shaft, and the other couplingEnglish Description connects the non-conductive short shaft to the shaft of the device. In this configuration, the motor is positioned perpendicular to the device to rotate the shields.Advantageous Effects of Invention

[0029] In this invention, changing the magnetic field within the conductor occurs without moving the source of the field, ensuring that, due to Lenz's law, the energy consumption of the system for electricity generation is minimized. The key advantages of this invention include:a. Low cost of manufacturing the device compared to the output it generates.b. Highly efficient energy production relative to the device's energy consumption.c. Generation of very inexpensive electricity without environmental pollution. d. A simple system with low maintenance costs.Brief Description of Drawings

[0032] Fig 3: Superconducting disc

[0033] Fig 4: Toothed ferromagnetic discDescription of Embodiments

[0034] In the drawing, there is a metal cylinder (1) with a hollow ring magnet (2) placed around it, and it is surrounded by a ferromagnetic shield (3) shaped like the English letter "C". A shaft (6) passes through the metal cylinder, which is connected to the conductive metal block (4) of the device via a ball bearing.Another conductive metal block is also present above the device, but it is not shown in the drawing.

[0035] The ferromagnetic shields can be attached to the shaft by a non-magnetic piece (5) (connection clamp), which can come in various shapes. As the shaft rotates, the shields rotate around the ring magnet. The rotation of the shaft canEnglish Description be driven by an electric motor. For this purpose, a gear (7) connected to the shaft can be used to transmit the power.

[0036] To prevent energy loss due to air resistance, a plastic cover can be placed between the shields (8) so that the lateral edges of the shields do not interact with the air, allowing the shields and shaft to rotate more smoothly. The thinner the shields (9), the more shields can be used, resulting in the generation of more electricity.

[0037] One or two superconducting discs (10) are placed above and below the ring magnet, and the holes within them can direct the magnetic field in and out of the ring of the magnet. Moreover, instead of using shields in the shape of letter "C", two toothed ferromagnetic discs (11) can be used. These two discs are placed above and below the ring magnet, parallel to each other, and the teeth must be aligned with each other to guide the field.

[0038] When the superconducting discs and the ferromagnetic discs are used, a conductive ring is installed around the magnet. In these two configurations, the current exits the device through the conductive ring. Additionally, the metal cylinder is connected to the conductive ring so that the current is transferred from the metal cylinder to the conductive ring. In this case, the conductive block does not become electrified.

[0039] If the edges of the teeth on the disc are slightly curved inward and have an edge, the field can be guided more effectively.

[0040] By placing non-conductive components, such as plastic, between the teeth of the discs, air resistance can be prevented, allowing the disc to rotate with less loss. It is very important that the teeth of the two ferromagnetic discs are perfectly aligned so that they can shield the field.

[0041] The screw that fastens the motor's holder base to the conductive block should not be electrically conductive, as there is a risk of electricity of the device flowing into the motor and damaging it. Additionally, insulating materials should be wrapped around the motor to prevent arcing from the device to the motor due to the high voltage generated in the device, and to prevent the motor from burning out.English Description Industrial Applicability

[0042] This invention is applicable in industries related to power generation for urban electricity consumption and manufacturing units, the production of optimized electric automobiles, supplying power for portable electrical devices, providing transportation power for trains and ocean-going ships, the production of electric machinery for road construction and mining, desalination of saline water for agricultural use, and generally in any area where rotating a shaft is required to perform a task.
