Description

System for generating electricity using a magnetic machine

[0001] The present invention relates to a system for generating electricity using a magnetic machine according to the preamble of patent claim 1.

[0002] Magnetic machines, or magnetic motors or drives, have been known for many years and can also be used to generate electricity. DE 20 2004 010 739 U1 presents such a magnetic drive, which uses permanent magnets or electromagnets to move a shaft back and forth, thus creating a rotary motion that can also be used to generate electricity.

[0003] The present invention now has the object of presenting a system for generating electricity with a magnetic machine, wherein the energy stored in a power storage device drives a magnetic machine for generating electricity, which enables an increase in the amount of usable electricity.

[0004] This object is achieved by a system for generating electricity using a magnetic machine having the features of patent claim 1. Further features and embodiments emerge from the dependent claims, and their advantages are explained in the following description.

Description

[0005] The system for generating electricity according to the invention comprises at least one electricity storage device 1, a magnetic machine, a controller 13 and a generator 6. The magnetic machine contains a closed container 5, which ideally has a cylindrical shape. Arranged inside the container 5 is a circular drive plate 4, which is connected to a generator 12 for generating electricity via a drive tube 6 made of a stable material, such as steel. The drive plate 4 can be a hollow helium sphere plate, for example. The drive plate 4 is equipped with at least four magnets 3 arranged in a circle, whereby these can be arranged on top of the plate, on the outer edge of the plate or even inside the plate. In the variant shown in Fig. 1, the magnets 3 are fastened to a magnetic levitation frame. Any two adjacent magnets 3 have different polarities, alternating between N and S.An electromagnet rail 2 connected to the container 5 is arranged in a circle, with two adjacent electromagnets 202 each having different polarities N and S. By regularly reversing the current direction in the electromagnets 202, they change the polarity and can thus, in interaction with the magnets 3, cause the drive plate 4 to rotate. The rotation of the drive plate 4 drives the generator 12 via the drive tube 6, generating electricity.

[0006] Fig. 1 shows a variant embodiment of an overall system in which the electromagnetic rail 2 is arranged on a round plate fastened to the lower end of the container 5 by means of a base 15, the magnets 3 moving around this plate. In addition, Fig. 1 also shows the connection to a power grid 23 with a connection 19 for feeding the generated power into the power grid 23, as well as a connection 18 with which the power storage device 1 can be recharged as required by the power grid 23. Alternatively, the power storage device 1 could also be charged via a direct connection 34 by other energy sources such as solar cells, wind turbines, hydroelectric power plants, fuel cells, etc.

[0007] The system includes various sensors 22-33 that communicate with the controller 13 and allow the system to be optimally configured depending on the operating mode. The sensors 22-33 can transmit the measured values, for example, via WLAN to a router 14, which is connected to the controller 13 via a cable connection 35. The electromagnets 202 arranged on the electromagnet rail 2 can be controlled via a cable connection 16 to the controller 13 and draw the required power from the power storage unit 1, also via a cable connection 17.

[0008] In one embodiment, the drive plate 4 is hollow and can be filled with helium so that its own weight can be compensated by the buoyancy of the helium. For this purpose, a compressor can be used. sensor 8 can be connected to a helium bottle 9 by a compressed air hose 21, so that the drive plate 4 can be filled with helium via a helium gas pipe 20 with a pressure valve 10 for the helium inlet.

[0009] Another embodiment provides that the container 5 is connected to a vacuum pump 7 via a pressure valve 11 so that a vacuum can be generated in the hollow space of the container 5.

[0010] Fig. 2 shows a simplified representation of a further possible embodiment of the invention, wherein the drive plate is spaced a distance d from the plate on which the electromagnets 202 are arranged. The distance d should be selected so that the interaction of the magnets 2 with the electromagnet rail 2 is as strong as possible, but no friction loss and also as little turbulence as possible arise, which could slow down the rotational speed.

[0011] In a preferred embodiment, the container 5 is cylindrical and the electromagnets 202 are arranged on a circumferential electromagnet rail 2. As shown in Fig. 3 and Fig. 4, the electromagnets 202 can be designed as simple drive coils 202, which each attract the magnets 3 on the drive plate 4 of the opposite polarity. As soon as the drive plate 4 has rotated far enough that the magnetic force of the electromagnets 202 acts too strongly against the direction of rotation, the drive coils 202 change polarity, so that the drive plate 4 continues to rotate. By correspondingly increasing the frequency of the reversal of the polarity By actuating the electromagnets 202, the rotational speed of the drive plate 4 can be increased or reduced.

[0012] In order for the drive plate 4 to move as little as possible in the vertical direction, it is important that the magnetic force of the electromagnets 202 and the magnets 3 is sufficiently strong. On the other hand, the electromagnet rail 2 can additionally be provided with twisted figure-8 coils 222, as shown in Fig. 5. Due to the magnetic field created by the electromagnets 202 with the magnets 3, a current flows in these coils 222, which in turn creates a magnetic field in the coil 222. Due to the figure-8 design, this second magnetic field has different polarity above and below and therefore acts on the magnets 3 in such a way that an upward force acts on the magnets 3 and thus on the drive plate 4 as soon as the drive plate moves downwards and vice versa. In this way, if the drive plate rotates quickly enough, it floats at a constant height in the container 5.To prevent the drive plate 5 from falling when the electromagnets 202 are not in operation, it can be equipped with wheels that touch the bottom of the container and thus enable the magnetic machine to start up. In one variant, these wheels can be retracted above a certain rotational speed.

[0013] In order to ensure that the drive plate 4 rotates not only at a constant height but also centered in the cylindrical container 5, two opposite 8-shaped coils 222 are connected to each other. , which means that the magnetic field of a first coil 222 becomes stronger as the distance between the magnets 3 and the coil decreases, and at the same time, on the opposite side, the magnetic field of the second coil 222 becomes weaker. As a result, a force is generated in the direction of the center of the drive plate 4 with the stronger magnetic field, which ensures that it remains centered.

[0014] In a particularly preferred embodiment, the magnets 3 are superconducting magnets. These have the advantage that once charged with an excitation current, they generate a circulating direct current and a strong permanent magnetic field without loss and thus, like a permanent magnet, constantly generate a magnetic field without the need for energy. In order for these superconducting magnets to function, however, they must be cooled. This can be achieved, for example, with a cooling system using liquid helium so that a temperature of less than 4.5 K can be achieved. In this arrangement, it is advantageous if the magnets 3 are inside the drive plate 4 and are therefore located in a cavity filled with, in this case, liquid helium. If the liquid helium evaporates, it is cooled again by a helium compressor and a refrigeration unit and can thus flow around the superconducting magnets 3 in the circuit and cool down.

[0015] To prevent the superconducting magnets 3 from absorbing heat from the outside via radiation, a radiation shield is installed around them or around the entire magnetic machine. Depending on the situation, this radiation shield may also be advantageous, for example cooling with liquid nitrogen and / or maintaining a vacuum inside and around the container to prevent convective heat transfer.

[0016] In a further embodiment, at least one sensor 30 is arranged to record a measured value that provides information about the performance of the magnetic machine. This sensor could, for example, record the number of revolutions of the drive tube or the power of the power generator. The controller 13 receives information from this at least one sensor 30 and can regulate the electromagnets 202 on the electromagnet rail 2 based on this information. The information from the at least one sensor 30 can be transmitted to the controller 13 via a cable or a wireless connection.

[0017] To regulate the pressure in the container 5, at least one second sensor 25 is provided, which measures the pressure in the container 5 and transmits this information to the controller 13. The controller 13, in turn, regulates the vacuum pump or compressor 7 to maintain the desired negative pressure in the container 5.

[0018] The presented system for power generation using a magnetic machine allows energy stored in a power storage unit to be increased as needed using the energy of magnetic fields. It can be used in various locations, for example, in vehicles, real estate, railways, aircraft, ships, or even in a magnetic power plant. Depending on the application, several systems can be assembled and linked together.

[0019] The magnetic machine and the system could also be very interesting in the real estate sector, where the generated electricity can be fed into the grid as needed. The corresponding monetary compensation for the electricity supply can be used to finance mortgages, extensions, new construction, and renovations, environmentally friendly property renovations, etc.

[0020] It's also possible to power space gliders, for use by the Red Cross and hospitals, for example. With appropriate dimensions, an entire emergency center could be built into the space glider. The space glider could also relieve the burden on the transport system or be used in agriculture.

[0021] The system can be used universally to provide basic services in municipalities, federal states and cantons.

[0022] This can result in a significant reduction in the load on the network operators through the entire electricity exchange between private individuals, industry, commerce and the real estate sector to ensure the Basic services .
