    Abstract

    The invention relates to a generator of electrical current by movement and induction by means of permanent magnets and resonant coils according to an envelope housing a circular solid element in the form of a rotor in which a variable magnetic flux is generated by incorporating thirty-eight permanent and rectangular magnets arranged such that they are radially aligned on the outer periphery of said rotor, and rotating inside a stator which has an annular shape and is hollow so as to carry out the cooling on the inside thereof, containing seventy-six idle coils which are regularly distributed and between which resonant capacitors and coils are alternated with non-resonant coils, arranged specifically three millimetres from the magnets, from which electrical current is generated with a very high efficiency.

    Claims

    1. Electrical current generator based on the movement and induction of permanent magnets and resonant coils characterised by having an external stator and internal rotor comprising a solid circular shape including permanent magents in which a variable magnetic flux is generated based on the rotation inside the stator. The stator is made up of a system of static coils where resonant coils and condensers are placed between non-resonant coils, arranged specifically three millimetres from he magnets that make up the outer perimeter of the rotor, where the variable magnetic flux is converted into electricity based on the configuration of the following elements: A. Circular rotor that holds thirty-eight rectangular magnets arranged radially around the outer perimeter of the rotor, such that the north-south axis of the magnet is perpendicular to the radius that passes through it and the north pole of the magnet points clockwise in the direction of rotation, joined to an axis that is held in place at either end by ball bearings that allows for movement inside the stator. B. Stator in the form of a hollow ring with an internal diameter big enough to hold the magnet rotor; oval-shaped cross-section designed to allow cooling liquid to circulate. The stator will therefore have corresponding input and output ducts for the coolant, designed to ensure that the seventy-six coils that make up the stator are distributed evenly. C. Configuration of the coils that the stator contains where the resonant coils and condensers are placed between the non-resonant coils, such that each resonant coil is matched with a bank of condensers, creating an LC circuit tuned to 2,216.66 Hz, which is the magnetic flux variation frequency generated in the magnet rotor when it turns.

    EXAMPLE OF A PREFERRED EMBODIMENT WITH FIGURES

    [0059] FIG. 1 shows an example of the preferred embodiment of the Electrical current generator based on the movement and induction of permanent magnets and resonant coils used to produce electricity from a wind generator. It also shows how it can be implemented inside a circular case (1) in the form a chassis, made from aerospace grade aluminium, 10 mm thick with a 400-mm diameter, fitted with four spacers (4) also made from aluminium, to support the stator (3), which holds the group of 76 coils (4) that fill the space of the aforementioned stator (3). FIG. 1 also shows the input pipette (5) and the output pipette (6) of the cooling circuit of the coil group (4). Lastly, the configuration of the rotor (7) shows how it turns around a central axis (8) and holds the 402010 mm neodymium magnets (9) with a power of 2500 gauss, as well as the aluminium wedges (10) needed to hold the magnets in place.

    [0060] FIG. 2 shows an elevation view of the radial section. Here it is possible to see the aluminium rotor group (7), which has a diameter of 230 mm, with the magnet group (9) placed around the perimeter, as well as the location of the 22-mm diameter steel axis (8) which is responsible for the angular movement. It is also possible to see the set of coils (4) wound around the hollow, oval-shaped copper ring (11) allowing cooling liquid to circulate.

    [0061] FIG. 3 displays a main plan view of the rotor (7) to show the distribution of the magnetic poles of the magnets (9) around the perimeter of the rotor. The intensity of the magnetic flux (12) is also represented in the shape of a sinusoidal or variable curve.

    [0062] Lastly, FIG. 4 shows an elevation view with the distribution and connection of the resonant coils of the even group (13) with its banks of condensers (14) and the group of non-resonant coils (15) which are placed in an alternate way or between each of the coils of the even group (13). In the figure, we can also see the rotor group (7) and the representation of the intensity of the magnetic flux of the magnets (12) and how the coils are arranged radially (13 and 15), such that the internal corners of each adjacent coil are aligned.

    [0063] Regarding the connection with the specific application that is the object of this preferred embodiment, FIG. 5 shows a diagram of the wind generator that benefits from this invention, and which would make it possible to reduce the size of the propeller (16) of the generator group, thanks to the smaller amount of energy needed for operation. Thus, the generator that is the object of this invention (17) is coupled using centrifugal clutches and a transmission set (18) to the drive propeller (16) and a small 3 KW electric motor (19), which would make it possible to operate the generator (17) when there is no wind or when there is very little wind, using the electric motor (19). Said electric motor is supplied by an electronic speed control (20) and a battery set (21) which are kept charged by the charger circuit (22), which is supplied by 25 DC volts delivered by the rectifier group (23), which in turn is supplied with high-frequency alternate current from the group of odd and even coil groups of the proposed invention that is the generator.

    [0064] The buck converter chargers (24) are each supplying 25V and 200 A to banks of graphene supercapacitors (25). Said condensers each have a capacity of 3000 Farads and the corresponding outputs are connected to a direct current bus (26) with a capacity for 25V and 400 A, which in turn are connected to inverters (27) with capacity to generate 230Vac and 5 KW of power per converter, resulting in a total power level of 10 KW in the output bus (28).

    [0065] As we have seen above, the proposal is for a wind turbine that could generate enough power to supply a home or small farm, and solve the problem of conventional wind turbines that stop generating electricity when there is no wind or very little wind. Lastly, it is worth noting that as the storage capacity of the battery bank (21) increases, the greater the amount f time that the generator can be kept running, making it less dependant on whether there is enough wind or not.

    [0066] This descriptive report is considered sufficient so that any expert in the matter might understand the scope of the invention and the advantages which could be derived from its use in any application that could require electrical and/or mechanical power.
