Description

Gravitational engine.

The gravitational engine is an electric motor whose movement is produced by constant and controlled displacement of a series of existing masses in the rotor that, continuously, make up a resultant force that does not pass through the center of rotor gravity so that it rotates as a result of torque generated by said result whose value is the product of such force by the distance that separates it from the axis of rotation. He controlled movement of the masses in one way or another and always in radial direction, it produces, consequently, the rotation of the engine. Mobile masses, equal to each other, move, guided conveniently by their corresponding cameras, in the direction radial as a result of the lengthening or shortening of a special spring that supports each of them being the point of suspension on the outermost part of the rotor. The material of that the springs are manufactured is the key to the operation of this motor because as a result of its excitation by currents Low intensity electric variations occur in the dimensions of such springs.

Electric motors are part of almost all the devices normally used in our lives, since either in the habitual residence, private or public vehicles for ordinary movements, games and entertainment, gadgets medical use, sports, etc. That is, it would be very difficult to imagine a usual situation of our day in which some type does not intervene electric motor

Even any new device that We incorporate into our ordinary life can present advantages important if the motors or actuators you have are new generation. There are high power motors and also actuators miniature to execute almost imperceptible movements.

Yes it is true that the invention presented implies certain complexities linked to any prototype, developments are not ruled out later that, based on the fundamental idea, allow important improvements that optimize the performance of this new engine

Description of the invention

The present invention relates to a new type of electric motor that is based on the use of some materials called electroactive ionic polymers. These materials they have the peculiarity of modifying their initial dimensions when subjected to the action of low electrical currents intensity.

The essential and novel part of the invention resides in the rotor that has a completely original design. This divided into multiple sectors, uniformly distributed, each of which houses a small mobile mass suspended from a spring of electroactive polymer. The rotor is initially in equilibrium and, therefore, at rest, having all its mobile masses symmetrically distributed and at an identical distance from the axis of turn. It is understood that if under any circumstances the cited balance of the masses, the rotor will begin to rotate with the tendency to reach a new equilibrium situation. So that the  movement is continuous it is also necessary to provoke a permanent imbalance continues.

Well, suppose, by any procedure, we move to the center one, two, three or more Consecutive masses and close to a horizontal radius of the rotor. In those circumstances the opposite part of the rotor accumulates a series of masses located at positions farther from the axis of rotation than the diametrically opposed with which, although the weight of the set remains unchanged, an imbalance of forces is generated whose resulting does not pass through the rotor shaft creating a torque. The rotor begins to rotate with a tendency to reach a position of equilibrium in which the masses of the right side have a resulting equal and symmetrical to those on the left side. But This engine's own design makes the masses that had displaced towards the center, recover progressively but quickly its initial position while other masses are displaced towards the center with which balance and the rotor are never reached rotates indefinitely until the cause that causes the displacement of certain masses towards the center of the rotor.

But now let's see the reason why certain masses suffer radial displacements approaching or moving away from the center of the rotor. That is precisely the key to invention since each mass is initially in a remote position from the center, it is suspended from a spring attached to the periphery of the rotor and, in the absence of excitation, said spring It has its minimum length. When an electric current circulates at through said spring, it experiences a manifest elongation as a consequence of the intrinsic properties of the material from which it is manufactured; the suspended mass of such a spring is Approaches the center of the rotor. If the electrical excitation ceases, the spring recovers its original length so that the mass is again in position near the periphery. A system of existing brushes and collector on the periphery of the rotor makes the springs receive and lose electrical excitation so sequential also producing the corresponding elongations and shortening that causes the rotor to rotate. On the other hand the piece that supports the brushes can rotate coaxially on the rotor shaft in such a way that it can cause an advance or a recoil in the process of feeding the springs with which a variation of the turning speed is achieved. The sooner it is produce the excitation of the springs, greater imbalance is produces and, consequently, the turning speed will be higher.

Start-up power is obtained by means of a battery that recharges automatically thanks to the existence of a series of permanent magnets arranged in the rotor and a series of coils installed in the stator running The whole as a magnet. In addition another set of magnets permanent rotary and fixed coil allow to generate energy electric that can be used for other purposes.

Description of a preferred embodiment

The gravitational engine (Figs 1, 2 and 3) in one preferred embodiment, consists of an electric motor whose key is the use of electroactive ionic polymers materialized in special springs whose dimensions vary when they are traveled by electric currents. The engine consists of a rotor (3) in the form of a revolution cylinder whose axis can turn on the support (2) supported in turn on the base (1). Rotor (3) It is divided into a series of solid sectors intended for embedding of permanent internal magnets (5) adjacent to a series of cameras (10) designed to accommodate the springs electroactive (12) fixed by its outer end to the rotor (3) and joined at the other end to masses (13) such that the mass movement (13) occurs radially when the length of the electroactive springs varies (12). The figures 1, 2 and 3 represent the case of a symmetric division into twelve parties, for reasons of simplification in this description, but the number of parts may be higher depending on the size of the engine and purpose to which it is intended.

The rotor (3) has, on both sides, wings in "L" shape that allow the embedding of another series of permanent external magnets (4) facing the corresponding ones permanent internal magnets (5). The permanent magnets (4) and (5) they constitute the inductive elements of electric generators complementary auxiliaries of the present invention.

The rotor (3) also has, in its part more external, corresponding to the generatrix of the cylinder revolution, a series of pairs of algae (11) that, connected electrically at the beginning and end of each electroactive spring (12) constitute the motor manifold for feeding and excitation of the springs (12) through the brushes (14) in solidarity with a brush holder (6) that can be fixed, or can rotate at will coaxial shape to the rotor shaft (3).

The stator of the auxiliary generators is constituted by a series of coils (9), as many as magnets external permanent (4), supported half of them by the inner stator (7) and the other half by the outer stator (8).

Let's see now how the engine of the present invention as conceived by its inventor. At the beginning the rotor (3) is at rest as a result of the balance of the set in which the right semi-rotor in addition to weigh the same as the left semi-rotor, it has a resultant force that passes exactly along the axis. When An electric current is circulated through one of the springs electroactive (12) feeding from a battery (no represented) by means of the brushes (14) through the thin (11), an elongation of said spring (12) occurs that shifts its corresponding associated mass (13) towards the center of the rotor (3) which breaks the initial balance and although each semi-rotor still weighs the same, the result of the masses located to the right and left of the vertical plane that passes through the axis, it is not contained in said plane and, therefore, generates a torque that causes the movement to start. He The rotor's own movement (3) causes the electroactive spring supply (12) adjacent to the previous one which, when increasing its length, causes the approach of its mass respective (13) towards the rotor shaft (3) whereby the imbalance increases and the torque also increases. Subsequently, the springs are fed and elongated (12) following and ceases feeding in those who were excited previously with which they are recovering their resting length. This occurs precisely when each spring (12) and its corresponding mass (13) pass through the highest point and in that way the resulting one is always out of the vertical plane that passes through the axis and the torque remains active. It is understood that as consequence of rotor rotation (3) and due to the existence of permanent magnets (4) and (5) and their corresponding coils (9) are produces the generation of electrical currents that can be used, one part, to feed the engine itself, and the rest For other purposes.

For a better understanding of the process, it has been shown in figure 3 a rest situation (left) with the deactivated electroactive springs (12) and another (right) with some contiguous springs excited (12 '). The brush holder (6) it is in a horizontal position whereby there are three excited springs (12 ') (all three in the upper right quadrant) (the rotor rotates to the counterclockwise) Also note that as that approach the top point the springs are losing length.

If we rotate the brush holder (6) towards below, the excitation of the springs would begin earlier, the imbalance would be greater and the rotor (3) would spin faster. By on the contrary the turning speed would be lower if we move the brush holder (6) up. It is also conceived a possible speed regulation by varying the intensity of the excitation current of the springs.

The brush contact system (14) with the thinner (11) it softens, to minimize friction, by Medium miniature bearings.

Since the basic foundation of this invention it is the rotation of the rotor (3) as a result of an imbalance provoked and controlled of its mobile masses (13) the inventor also considers the possibility of producing such an imbalance by a different procedure from the incorporation of polymers electroactive ionic in the mass suspension springs, thus conceiving the solution of the masses being magnets permanent suspended steel springs that would approach the center of the rotor when repelled by an external inductor magnet that, in this case it would work as a replacement for the brush holder and power supply The masses of permanent magnets next to the inductor magnet are those that cause the imbalance, recovering their normal position as soon as they move away from the influence of the inductor. This avoids direct contacts by eliminating consequently the friction inherent in the brushes.

You can also think of any other mechanical procedure that causes controlled displacement and successive of the masses within their chambers, resulting in In any case, a rotational movement of the rotor.

It is not considered necessary to make the contents of this description more extensive so that a person skilled in the art can understand the scope, originality and advantages derived from the invention, as well as develop and implement the object of the
same.

However, it should be understood that the invention has been described according to a preferred embodiment thereof, so which may be subject to change without implying any alteration of the basis of said invention, being able to affect such modifications to the shape, size and / or Manufacturing materials; that is, the terms in which it has remained Exposed this preferred description of the invention, should be always taken with a broad and non-limiting nature.
