Description

[0001] This invention relates to a generator, and more particularly to a magnetic induction generator. Technical Field

[0002] More specifically, the present invention relates to an electromagnetic device of the aforementioned type, comprising an electric coil specifically designed and constructed to supply power from a magnetic field generated by a free magnet without requiring relative movement of the magnet relative to the electric winding. This electromagnetic device is suitable for situations requiring a reduction in the size of the generator, but can be used in any application requiring the generation of electricity.

[0003] The following description will be directed toward the field of wind energy, but it should not be assumed that the invention is limited to this particular use. Background Technology

[0004] As is well known, in an electric motor, the stator may consist of permanent magnets primarily used in DC motors or generators, or may include electrical windings. This second configuration is typically used in systems, for example, including AC motors, brushless motors, and stepper motors, where the stator comprises steel and silicon alloy laminations of varying thicknesses, or is made of solid steel and insulated from each other.

[0005] As is known, among the types listed above, brushless motors (similar to generators) are equipped with electronic structures featuring phase-change operation, allowing for high speeds, such as up to 10,000 rpm. In addition to high speeds, brushless motors also offer the advantages of low rotor inertia, low electromagnetic interference, and the elimination of the need for maintenance-free brushes, as brushes are absent. In this sense, brushless motors are considered the motor of choice for a wide range of applications, including those requiring high precision and high efficiency.

[0006] Typically, the construction of such motors requires the presence of a stator and rotor that are usually circular to maximize power output.

[0007] However, the complex and heavy structure is not convenient for applications where the size of the motor is comparable to the size of the device to be powered, or where the weight, for example in the case of wind turbines or micromotors, may affect the efficiency of the device itself.

[0008] Clearly, there is a need to provide a generator that can overcome the problems listed above.

[0009] It is also evident that there is a need to provide a high-efficiency, lightweight, and low-cost generator that is suitable for applications requiring high electrical efficiency, such as in the wind energy sector. Summary of the Invention

[0010] In view of the above, the object of the present invention is to provide a magnetic induction generator equipped with a rotor including magnets and electrical windings arranged in a stationary manner, and also equipped with ferromagnetic components capable of moving relative to these windings.

[0011] Another objective of the present invention is to provide an electromagnetic device equipped with a ferromagnetic component (e.g., ferrite), wherein the electrical winding is decoupled from the rotor of the device itself.

[0012] Another object of the present invention is to provide a generator equipped with a magnet and electrical windings and having a magnetic field whose intensity and direction are variable, which is capable of generating electrical energy without requiring relative movement between the magnet and the windings.

[0029] In various accompanying drawings, similar parts will be indicated by the same reference numerals.

[0030] refer to Figure 1 The generator 1 includes: a pair of permanent magnets 11 and 12, which extend along a first Y-axis in a principal direction and are arranged parallel to each other; a first ferromagnetic assembly 21 and a second ferromagnetic assembly 22, which extend substantially perpendicular to the first Y-axis in a static configuration and are rotatable about a rotation axis 5. The rotation axis 5 is perpendicular to the first Y-axis, therefore, the first ferromagnetic assembly 21 and the second ferromagnetic assembly 22 can be arranged parallel to the first permanent magnet 11 and the second permanent magnet 12 individually during their rotation to form a closed circuit with the pair of magnets. The generator 1 also includes at least one electrical conductor 3, which is arranged to be wound around a first support section 31 placed between the first magnet 11 and the second magnet 12 of the pair of permanent magnets.

[0031] Refer again Figure 1 The generator 1 includes a frame 20 that connects the first ferromagnetic assembly 21 to the second ferromagnetic assembly 22. Furthermore, the frame 20 connects the ferromagnetic assembly to other ferromagnetic components (e.g., ferrite rods) inserted between the first support section 31 and the second support section 32, and between the first permanent magnet 11 and the second permanent magnet 12.

[0032] Specifically, the frame 20 connects the first ferromagnetic component 21 to the first rod 41 and the fourth rod 44, and the second ferromagnetic component 22 to the second rod 42 and the third rod 43, facilitating the rotation of these ferromagnetic components around the rotation axis 5. Further details relating to alternative forms of the frame 20 and its embodiments will be given below.

[0033] The first permanent magnet 11 and the second permanent magnet 12 form the pair of permanent magnets, and can be linear, semi-circular, or horseshoe-shaped or "U"-shaped. The first permanent magnet 11 is arranged in a mirror image of the second permanent magnet 12, such that the north pole of the first magnet 11 faces the south pole of the second magnet 12, and vice versa.

[0034] In some embodiments, the main length of each magnet is less than the distance between one magnet and another.

[0035] According to some embodiments, the generator may be equipped with an electrical winding 31 or coil wound around one or more magnets, one or more support sections and / or one or more ferromagnetic components wound around the generator itself.

[0036] from Figure 1 As can be seen from this, there is a winding 3 around the first support section 31.

[0037] According to some embodiments, a plurality of electrical conductors 3 may be wound around a plurality of support sections, for example, wound around a first support section 31 and a second support section 32 respectively.

[0038] Specifically, the first section 31 can be arranged between the first magnet 11 and the second magnet 12 such that the S pole of the first support section 31 faces the N pole of the first magnet 11, and the N pole of the first support section support 31 faces the S pole of the second magnet 12.

[0039] Similarly, the second support section 32 can be arranged between the first magnet 11 and the second magnet 12 such that the N pole of the second support section 32 faces the S pole of the first magnet 11, and the S pole of the second section 32 faces the N pole of the second magnet 12.

[0040] According to some embodiments, the first support section 31 and / or the second support section 32 may be made of a non-ferromagnetic material (e.g., carbon fiber).

[0041] According to some embodiments, the first support section 31 and / or the second support section 32 may include ferromagnetic components.

[0042] According to some embodiments, the presence of the ferromagnetic component and the size of the magnets 11 and 12 allow the first support section 31 and the second support section 32 to be arranged between the first permanent magnet 11 and the second permanent magnet 12 without requiring these permanent magnets to be connected to the support component between the first support section 31 and the second support section 32.

[0043] refer to Figure 2 The first ferromagnetic component 21 is shown in an operational configuration, wherein the first ferromagnetic component 21 rotates about a first rotation axis 5, wherein the first ferromagnetic component 21 is arranged between the first magnet 11 and the second magnet 12, close to the first magnet 11, and the first ferromagnetic component is shown as parallel to the first Y-axis.

[0044] Still in Figure 2In the diagram, the second ferromagnetic component 22 is shown in an operational configuration, wherein the second ferromagnetic component 22 rotates about the first rotation axis 5, is arranged between the first magnet 11 and the second magnet 12, is close to the second magnet 12, and is shown parallel to the first Y-axis.

[0045] Figure 2 Also shown are, for example, a first pair of two ferrite rods 41 and 44 inserted between the respective magnetic poles of the first support section 31, which may be ferromagnetic, and the first permanent magnet 11, and a second pair of ferrite rods 42 and 43 inserted between the respective magnetic poles of the first support section 31 and the second permanent magnet 12, wherein the two pairs of ferromagnetic assemblies are rotatable about the rotation axis 5 and are integrated with the rotation of the at least one first ferromagnetic assembly 21.

[0046] Additional ferromagnetic components can be used to replace ferrite rods 41, 42, 43 and 44.

[0047] refer to Figure 3 The side view of the generator is shown in one of its operating phases, in which the lateral profiles of the first permanent magnet 11, the first ferromagnetic assembly 21 and the pair of rods 41 and 44, as seen from the outside, are in relative rotation about a rotation axis that coincides with the center of the permanent magnet 11.

[0048] Similarly, a second pair of ferrite rods 42 and 43 or multiple ferromagnetic components arranged near the second permanent magnet 12 ( Figure 3 (Not shown) can rotate around the rotation axis 5 due to the attraction and repulsion of the second magnet and the second ferromagnetic component 22.

[0049] According to some embodiments, a first support section 31 is arranged on or around a portion of a first beam 310, which in turn is arranged between a first permanent magnet 11 and a second permanent magnet 12.

[0050] Similarly, from Figure 4 and Figure 5 It can be seen that the second support section 32 is arranged on or around a part of the second beam 320, which is in turn arranged between the first permanent magnet 11 and the second permanent magnet 12.

[0051] The first beam 310 and the second beam 320 may be made of non-ferromagnetic materials (e.g., carbon fiber). Other materials that are not subjected to magnetic fields may be used as beams.

[0052] Now for reference Figure 5 The frame 20 includes, for example, a rotating portion 200 coinciding with the rotation axis 5 and an anchoring portion. Specifically, the rotating portion 200 is rotatable. Figure 5 In the example, the anchoring portion of the rotating portion 200, which is perpendicular to the anchoring portion, rotates sequentially.

[0053] Furthermore, the anchoring portion 201 or 202 may include one or more beams, such as two beams, or four beams 201', 201'', 202', and 202'', as shown below. Figure 5 As shown, multiple ferrite rods 41, 42, 43 and 44 are used to anchor them.

[0054] The presence of beams 310 and / or 320 reduces the risk that external disturbances may modify the field experienced by the winding 3 of the electrical conductor, and thus ensures the stability of the first support section 31 and / or the second support section 32.

[0055] Furthermore, the presence of beams 310 and / or 320 ensures the mechanical stability of the generator, thereby preventing possible movement of the first support section 31 and / or the second support section 32 and / or undesirable proximity of the two magnets.

[0056] refer to Figure 5 Beams 310 and 320 are arranged at distances from the axis of rotation 5 that are respectively greater than the distances between the first anchoring portion 201' or 202' and the second anchoring portion 201'' or 202'' of the frame. This positioning of the beams allows the frame 20 to rotate undisturbed about the axis of rotation 5, and the first ferromagnetic assembly 21 and the second ferromagnetic assembly 22 connected to the frame 20 can rotate about the axis of rotation in response to the magnetic field of the pair of magnets.

[0057] In some embodiments, only the first ferromagnetic component 21 is present in the generator, and the frame 20 may be coupled to a pair of ferromagnetic rods or a plurality of rods, such as four rods, which are connected to the center of the frame 20 or to a plurality of points of the rotating portion 200 of the frame 20.

[0058] According to a preferred embodiment, the rotating portion 200 coincides with the rotation axis 5.

[0059] According to some embodiments, in addition to being shared among these ferromagnetic components, the rotation axis 5 of two or more ferromagnetic components can be retractable, i.e., arranged in the same direction and configured to modify the distance between the two or more ferromagnetic components.

[0060] Specifically, the rotating part 200 may be composed of a hollow outer component and an inner component that is slidably connected to the outer component, thereby allowing the length of the rotating part 200 to vary.

[0061] In this way, two or more ferromagnetic components, such as those indicated by component symbols 21 and 22, can be brought closer together and / or further separated to modify the shape and strength of the resulting magnetic field.

[0062] In some examples, generator 1 is configured to promote the rotation of magnets about axis 5 in the opposite direction to the rotational directions of ferromagnetic components 21 and 22. Therefore, ferromagnetic components 21 and 22, as well as permanent magnets 11 and 12, can all rotate about this axis 5.

[0063] In some examples of the invention, there may be one or more pairs of ferromagnetic components arranged along a plane, including a pair of magnets, and at least another pair of ferromagnetic components arranged perpendicular to the plane. If the at least another pair of ferromagnetic components is capable of rotating while the magnets remain stationary, the arrangement of the pair of ferromagnetic components can be changed during generator operation.

[0064] According to some embodiments, the magnets can be arranged in a removable configuration such that the relative distance between at least one pair of magnets can be changed.

[0065] In this way, by modifying the distance between at least one pair of magnets, a similar technical effect to modifying the distance between ferromagnetic components can be achieved. In fact, changing the distance between magnets can cause a change in the strength and / or shape of the magnetic field.

[0066] Therefore, compared to generators where the position of a single magnet can modify the magnetic field itself, the possibility of adjusting the magnetic field by changing the relative positions of the ferromagnetic components and the relative positions of the magnets offers greater flexibility.

[0067] In this way, the device is configured to optimize power generation. For example, when using this generator inside a wind turbine, the ferromagnetic components are arranged at a predefined distance based on the wind intensity at turbine startup or the kinetic energy generated by the wind, and this distance is easily adjusted according to changes in wind intensity.

[0068] While other factors may interfere, the energy generated depends on the number of electrical windings, the rotational speed of the blades around their axis of rotation, and the strength of the magnetic field, which increases the braking force relative to the blades as the strength increases. Therefore, a proper balance of these components allows for optimized energy production.

[0069] Furthermore, the number of windings 3 surrounding the support section determines the generator's stability. In fact, a large number of windings reduces motor shaft vibration due to the attenuation generated by the windings themselves during the transition between the magnetic fields of one phase and the magnetic fields of subsequent phases.

[0070] Therefore, once the number of windings sufficient to guarantee the required stability of the generator while maintaining a sufficiently low weight and / or size to avoid slowing rotation about the rotor's axis of rotation—for example, the number of rotating blades in a wind turbine—has been defined, generator optimization can be determined by compromising the rotor's rotational speed with the strength of the magnetic field. The strength of this magnetic field can be modified through different configurations of several pairs of ferromagnetic components.

[0071] refer to Figure 6a , Figure 6b and Figure 6c An embodiment of a generator is shown, in which a coupling element is provided, wherein a first gear 61 acts on a second gear 62 in contact with it (two gears in contact), and two large permanent magnets 11, 12 are provided. These permanent magnets are horseshoe-shaped, i.e., "U"-shaped, and arranged such that the principal directions of each are parallel to a first Y-axis. Specifically, the central portions of the first permanent magnet 11 and the second permanent magnet 12 are arranged parallel to the first Y-axis, and the end of each magnet faces the other magnet. Specifically, the arrangement of these permanent magnets 11, 12 specifies that the north pole of the first magnet 11N faces the south pole of the second magnet 12S, as shown in the diagram. Figure 6b As shown in the image.

[0072] refer to Figure 6a and Figure 6b The generator has two pairs of larger ferrites, each pair forming corresponding magnets 11 and 12. In addition, the generator includes four smaller ferrites 41, 42, 43, and 44 than the first four ferrites.

[0073] In some embodiments, eight smaller ferrites are arranged such that the first four ferrites 41, 42, 43, and 44 are positioned at the ends of the two anchoring portions 201 and 202, while the remaining four ferrites are positioned at two other anchoring portions, respectively perpendicular to the first anchoring portion 201 and the second anchoring portion 202. Figure 6b (Not shown in the text) at the end.

[0074] The first component 21' (preferably a ferromagnetic component) is rotatable about the rotation axis 5 in such a way that, in a stationary configuration, the first component extends substantially perpendicular to the first Y-axis and is positioned between the two magnets.

[0075] The number of such components can vary. In fact, in some embodiments, there are two components 21'a, 21'b perpendicular to each other in the portion near the first magnet 11, and two components 22'a, 22'b perpendicular to each other in the portion near the second magnet 12.

[0076] In some embodiments, the number of each part may vary, such as four or six components. Preferably, these components are protrusions that project from the shaft 200, are arranged around the shaft 200, and are equidistant from each other (i.e., arranged similarly to a beam around the shaft 200).

[0077] Figure 6b Four ferromagnetic components 41, 42, 43, and 44 are shown inserted between the first support section 31 and the respective magnetic poles of the two permanent magnets 11 and 12.

[0078] because Figure 6b The embodiment shown also presents a second support section 32 located downstream of the generator in the middle position, so that, corresponding to the first support section 31, four ferromagnetic components 41, 42, 43, 44 are also inserted between the second support section 32 and the respective magnetic poles of the two permanent magnets 11, 12.

[0079] from Figure 6b It can be seen that the rotating part 200 of the frame 20 is a rotating axis extending along the second axis.

[0080] It should be noted that since the four ferromagnetic components rotate as a unit with the rotating shaft 200, when the first ferromagnetic component 41 is inserted between the first section 31 and the magnetic pole 11N of the first magnet 11, the second ferromagnetic component 42 will be placed between the first section 31 and the magnetic pole 12N of the second magnet 12.

[0081] Figure 6b The four ferromagnetic components 41, 42, 43, and 44 of the embodiment shown have a smaller size than the two permanent magnets 11 and 12.

[0082] refer to Figure 7a , Figure 7b and Figure 7c An embodiment of the generator is shown, wherein two belts 71, 72 respectively initiate the rotation of pulleys and / or gears 63, 64 and 65, 66.

[0083] In addition, some embodiments specify the presence of coils 110, 120 surrounding their respective magnets 11, 12, such that these coils are energized in a manner that improves the overall efficiency of the generator when the generator circuit is opened and closed.

[0084] Specifically, this efficiency improvement occurs whenever the circuits of the two main magnets are opened and closed, due to the increased current flowing through the additional coils 110 and / or 120.

[0085] The presence of two gears 71 and 72 has the following advantages: it provides a more balanced system compared to a system equipped with a single gear 61 or a pair of gears 61 and 62 arranged near a magnet (e.g., a second magnet 12).

[0086] Some embodiments specify the presence of a crank 8, which is operatively connected to a second rotating shaft 200' to initiate the rotation of pulleys 63, 65, and thus cause pulleys 64, 66, which are integral with the first rotating shaft 200, to rotate.

[0087] refer to Figure 8a , Figure 8b and Figure 8c An embodiment of a generator is shown, which has large ferrite assemblies 11F and 12F arranged at two ends of the generator.

[0088] The ferrite components 11F and 12F arranged at the ends, combined with smaller magnets 110U, 110B, 120U, and 120B, essentially replace the permanent magnets 11 and 12, thus producing a similar effect. In fact, using two ferrite rods near the first and second magnetic poles, and near the third and fourth magnetic poles respectively, would achieve a similar but less intense effect.

[0089] Specifically, magnet 110U is inserted between the upper portion of the first ferrite assembly 11F and the first strip 71, while magnet 120U is inserted between the upper portion of the second ferrite assembly 12F and the second strip 72.

[0090] Similarly, the lower magnets 110B and 120B are inserted between the lower portion of each ferrite assembly 11F and 12F and their respective strips 71 and 72.

[0091] Therefore, according to other embodiments, components 11F, 110U and 110B are capable of performing the same function as the first permanent magnet 11, while components 12F, 120U and 120B perform the function of the second permanent magnet 12.

[0092] refer to Figure 8b In some embodiments, under the same external conditions, the strength of the magnetic field is lower than that of the generator according to the embodiment including two permanent magnets. This is because the magnetic poles tend to attract ferromagnetic rods, which are integral with the rotation axis 200 and cannot be translated along the axis. Therefore, apart from the strength of the generated magnetic field, the ferromagnetic rods can perform essentially the same function as the permanent magnets 11, 12.

[0093] The length of these rods can be comparable to the length of multiple ferromagnetic components 41, 42, 43, and 44.

[0094] refer to Figure 9a , Figure 9b and Figure 9c An embodiment of a generator is shown, which is provided with a series of coils arranged around a plurality of ferrites.

[0095] Figure 9b Two coils 311a and 311b surrounding two ferrites are shown, which constitute the positive and negative terminals of a first field generating assembly including a rotating current collector 11''.

[0096] When present, the two coils 311a and 311b rotate around the rotation axis 200.

[0097] This rotary current collector 11'' has an internal assembly capable of rotating the two input cables and the two output cables in a manner similar to that of a ball bearing.

[0098] The input and output cables are preferably made of copper wire.

[0099] The input cable is capable of rotating integrally with its respective coil when the output cable is not rotating. A rotating current collector 11'' prevents the coil cable from becoming tangled during its rotation. The rotating support connected to the gears and belt includes one or more ball bearings 9 coupled to supports 51, 52.

[0100] These supports 51, 52 are preferably columns with holes or with a profile complementary to the bearing 9.

[0101] The two pairs of ball bearings 9 can be supported in other ways without departing from the scope of protection of this invention.

[0102] Referring to Figures 10A and 10B, an embodiment of a generator is shown, which is equipped with three pairs of discs 630 / 630', 634 / 634', and 650 / 650', which rotate about a rotating support 200'' without relative movement to each other, due to the use of three pairs of ball bearings 9 that separate each pair of discs.

[0103] To increase the relative speed between the disks, some embodiments provide a central coil 3' that encloses a rod connecting two central disks 630, 630' to two belts 71, 72, which move the ferrite in one direction while the disks 630, 634, 650, respectively coupled to gears 640, 644, 660 (through contact), rotate in the opposite direction.

[0104] The operation of generator 1 described above is as follows.

[0105] When the generator is in a stationary phase, i.e. before it starts, at least one ferromagnetic component 21 is arranged perpendicular to the main dimensions of the first permanent magnet 11 and the second permanent magnet 12.

[0106] A mechanical or electrical event triggers the rotation of frame 20, to which at least one ferromagnetic component 21 is connected. In practice, the generator can be connected to an electric drive system or mounted on a wind turbine.

[0107] This mechanical or electrical event can be, for example, wind in the case of a wind turbine. In other applications, it can be current from a low-intensity generator or a starter battery connected to generator 1.

[0108] Therefore, rotating the frame around the axis of rotation allows at least one first ferromagnetic component 21 and multiple ferromagnetic components to rotate around the axis of rotation 5, and thus generates electrical energy.

[0109] The generator can also be connected to an energy accumulator and / or devices that require energy for their operation.

[0110] Therefore, the electrical energy generated by the generator can be supplied to the devices connected to the generator.

[0111] advantage

[0112] The advantage of this invention is that it provides a magnetic induction generator equipped with a magnet and an electrostatic winding, and also equipped with a ferromagnetic component that can move relative to these windings.

[0113] Another advantage is that it is supplied by a generator, in which the electrical windings are mechanically decoupled from the rotor of the device.

[0114] By again utilizing the generator according to the invention, a magnetic field with variable strength and direction can be obtained, thus providing flexibility in use.

[0115] The invention has been described for illustrative but not limiting purposes according to preferred embodiments thereof, but it should be understood that modifications and / or variations may be introduced by those skilled in the art without departing from the relevant scope defined in the appended claims.
