Description Field of the art

The present invention operates in the scope of transformation of a primary energy source into electrical energy, starting from a pair of magnets in rotary movement.

Prior art

The production of electrical energy occurs via energy conversion, starting from a primary source through the power plants. In 1870, the coupling of the dynamo with the hydraulic turbine started the commercial production of electrical energy. The first thermal power plant was instead opened in New York in 1882 in order to supply the public lighting grid. Previously, the only way to produce electrical energy was through chemical reactions, i.e. by means of batteries.

Most of the power production techniques are based on the use of pressurized steam, in which the pressurized water is heated to very high temperatures due to the use of a primary energy source; the steam is conveyed towards the rotary machines termed steam turbines in which the steam is expanded, converting its enthalpic content into mechanical energy. Connected to the rotation shaft of such turbines are alternators which convert the mechanical rotation energy into electrical energy. The use of a steam turbine coupled to an alternator is common for the production of electrical energy from turbogas, nuclear, solar, thermo-dynamic and geothermal sources. Combinations of turbine-alternator are also common for the production from wind and hydro-electric sources, while only photovoltaic and the use of hydrogen in fuel cells do not involve rotating parts.

A problem shared by all turbine systems, which therefore involve a mechanical movement, is the dissipation of energy in the form of friction, heat or other energy dispersion forms: since such energy cannot be recovered, this constitutes a source of system inefficiency. Object of the present invention is therefore that of proposing an optimized device for transforming electrical energy starting from kinetic energy or a rotating magnet, eliminating any energy dissipation due to the mechanical friction. Such system is optimized by the capacity to exploit the rotational inertia of the magnet and by the friction reduction.

Such object is obtained by means of the characteristics described in claim 1, and other versions of the invention are provided in the dependent claims.

Description of the invention

According to the present invention, an optimized system is attained for transforming kinetic energy into electrical energy which effectively resolves the abovementioned problems.

The system advantageously comprises:

- an electric motor drivable by means of any one energy source, adapted to impart a rotary movement around the vertical axis to

- a first pulley installed above said electric motor, constituted by a prism with polygonal base on whose lateral faces first magnets are installed in an alternated manner. In other words, the base polygon of the prism that constitutes the first pulley is a regular polygon with an even number of sides. Still more in detail, this is at least one hexagon, preferably an octagon or another polygon with a greater number of sides, so long as there is an even number of sides. On the lateral faces of the prism, said magnets are advantageously installed with an order with alternated faces, i.e. after each face provided with magnet, there is a face without magnet.

- a second pulley, identical to the first pulley, installed at a maximum distance of 10 mm from said first pulley. Advantageously, the two pulleys will be installed in a manner such that, by rotating, they act as toothed wheels, i.e. faces provided with magnet of one pulley face the faces lacking magnet of the other pulley and vice versa. Following the rotation of the first pulley, due to the action of the electric motor, the magnets of the first pulley thrust magnets of the second pulley, causing a “sling effect” which, since lacking mechanical friction, imparts an optimized rotation force to the second pulley. The second pulley is advantageously installed above

- an alternator, adapted to transform the kinetic energy in inlet into electrical energy;

- a first electric circuit adapted to collect a part of the electrical energy in outlet from the alternator in order to power supply the electric motor. The electric motor, therefore, will only require a first activation by using an external energy source, e.g. a common transformer, in order to then be self-supplied by the system, object of the present invention.

- a second electric circuit collects the remaining energy in order to deliver it to any one user device or store it in batteries.

Advantageously, common mechanical fixing and abutment means can be provided in order to ensure the stability of each component of the system.

In a further version of the present invention, above the electric motor and below the first pulley, a speed regulator is installed which allows controlling the number of revolutions/minute or revolutions/second at which said first pulley is rotated.

Independent of the characteristics of each possible embodiment according to the aforesaid parameters, the ratio between the electrical power absorbed by the electric motor and the power of the alternator is comprised between 1 :5 and 1 : 12, preferably 1 : 10, making the system decidedly advantageous.

The advantages offered by the present invention are clear in light of the description set forth above and will be even clearer due to the enclosed figures and the relative detailed description.

Description of the figures

The invention will be described hereinbelow in at least one preferred embodiment by way of a non-limiting example with the aid of the enclosed figures, in which:

- FIGURE 1 shows the various mechanical components that constitute the system of the present invention.

- FIGURE 2 illustrates an axonometric view of the components of the preceding figure assembled in order to form an operating machine.

Detailed description of the invention

The present invention will now be illustrated as a merely non-limiting or non-constraining example, referring to the figures which illustrate several embodiments relative to the present inventive concept.

With reference to FIG. 1, the technological components are shown which, when assembled together, form the system of the present invention. Omitted from this specific drawing are the possible mechanical fixing means 9 that ensure the stability of the object and which can vary depending on the design without altering the object of the invention.

Said components are:

- an electric motor 1, with speed regulator, with power equal to 37 W;

- a 420 W two-pole alternator;

- a transformer 6 of electrical energy to be connected to a fixed power grid;

- a pair of pulleys 4-4’ with octagonal shape that can be inscribed in a 90 mm diameter, to be respectively installed above said alternator 2 and above said electric motor 1;

- eight neodymium magnets 4.l-4.2-4.l’-4.2’ with parallelepiped shape and with dimensions equal to 35 mm X 14 mm X 7 mm with attraction force equal to 12 Kg, four of which to be installed on the lateral faces of the first pulley, with alternated faces, and the other four on the lateral faces of the second pulley, with alternated faces.

With reference to Fig. 2, the assembled system is shown.

It is observed that the two pulleys 4-4’ are installed at very small distances from each other, such that they never touch each other when rotating but the magnets with which they are provided mutually thrust each other. More precisely, the first magnets 4. G-4.2’-...’ of the first pulley 4’ impart a rotary movement to the second pulley 4 by means of the relative second magnets 4.1 -4.2- ... ,

In summary, by driving the electric motor 1 by means of a transformer 6 or another energy source, the first pulley 4’ will start to rotate, consequently also rotating the second pulley 4. Said second pulley 4 will drive the alternator 2 which develops a power 10 times greater than the absorption of energy by the electric motor 1.

Downstream of the alternator 2, its electric circuits are present:

- a first electric circuit 3’ adapted to collect a part of the electrical energy in outlet from said alternator 2 in order to power supply the electric motor 1;

- a second electric circuit 3 adapted to collect the remaining energy in order to deliver it to any one user device or store it in batteries.

Finally, it is clear that modifications, additions or variations obvious for the man skilled in the art can be made to the invention described up to now, without departing from the protective scope that is provided with the enclosed claims.
