Livros e Mapas! The fatigue problems of the resilient member are also eliminated since the stiffness of the mechanism is mediated only by magnetic forces. A frame 1 which transmits excitation vibration to the movable member 2 by means of the magnetic stiffness of the fixed permanent magnets 4 in combination with the movable magnet 3 on the movable member 2. The frame 1 accommodates a housing 5 in which the hinge 6 rolls / rotates with the movable member. In order to ensure point or linear contact of the housing with the hinge, it is preferable that the resilient member, which is formed by fixed permanent magnets fixed in the frame and one or more movable permanent magnets, position the fixed and movable permanent magnets relative to each other. The mechanical guidance of the movable member 2 is formed by means of a bearing hinge 6 fixed to the movable member 2 in the housing 5. There is only a linear or point contact, and the movable member 2 thus placed is subjected to very low mechanical damping forces, i.e.

On each side of the movable permanent magnet 3 located on the movable member 2, a fixed permanent magnet 4 is arranged in the frame. The hitherto used structure of the resonant mechanism of the vibration generator has an effective mass body placed on a fixed beam or a spring forming a resilient member. The design of the coil 7 is designed according to the required magnitude of the induced voltage (wire length), the dimensional constraints of the vibration generator, the magnitude of the excited oscillating movement of the movable member 2 with the excitation circuit 8, but also the magnitude of the connected resistive load. 2o It is obvious that the whole design of the electromagnetic vibration generator must be tuned so that the excited vibration generates the maximum possible power. The energy from the mechanical vibration of the system is obtained by a vibration generator whose structure is tuned to the excitation vibration and is optimally designed with respect to the required generated power and other requirements for this device.

An appropriate and tuned vibration generator will operate as a continuous power source throughout the machine’s operation. BACKGROUND OF THE INVENTION The present invention relates to an electromagnetic vibratory generator for generating electric power comprising a movable member having a flexible priced array, an excitation circuit fixed to the movable member, and a coil, the coil and excitation circuit being movably arranged relative to each other in such a way that voltage in the coil. The movable member 2 thus mounted allows the use of very low vibration intensities to excite relative movement and thereby generate useful output power. In order to obtain a sufficiently large generated voltage and power, the electromagnetic vibration generator needs a corresponding excited relative movement of the resonance mechanism, which causes a sufficient change in the magnetic flux in the coil winding, thereby inducing a sufficient electromotive voltage. As is evident from the entire description of the design of the electromagnetic vibration generator, it is a very complex technical system that utilizes the concept of the design of the resonant mechanism using a magnetic resilient member as shown in Figures 3a and 3b. The design of the coil 7 and the excitation circuit 8 substantially depends on the input parameters, power, maximum size, weight, frequency and amplitude of the vibrations.

The movable permanent magnet (s) 3 is fixed to the movable member of the generator 2 and is repelled by magnetic forces from the fixed permanent magnet 4 fixed in the frame 1 of the generator. The function of the electromagnetic vibration generator described above is as follows: the movable member 2 with the movable permanent magnet (s) 3 is positioned between the fixed permanent magnets 4 fixed in the frame of the vibration generator so that the movable permanent magnet 3 and the fixed permanent magnets 4 the magnetic forces that create the rigidity of the vibration generator (the repulsive magnets form a resilient member). The main advantage of the arrangement of the electromagnetic vibration generator can be seen in it. That the stiffness in the resilient member of the vibration generator resonance mechanism is formed by repelling permanent magnets.

4o The fixed and movable permanent magnets 4, 3, 4 forming the resonant resilient member also define the maximum amplitude of the oscillating movement of the movable member 2 with the excitation circuit 8. A suitably geometrically designed shape of the movable magnet 3 relative to the fixed magnet 4 defines the maximum oscillation amplitude of the movable member 2. the maximum approximation of the magnet 3 to the fixed magnet 4 results in a high magnetic force. A magnetic excitation circuit 8 is fixed to the movable member 2, which, due to its excited movement relative to the coil 7, induces an electromotive force and the resistor load connected to the generator draws the output power. During this movement, an electromotive voltage is induced in the fixed coil located in the air gap of the magnetic circuit.

SUMMARY OF THE INVENTION The object of the present invention is to provide an electromagnetic vibration generator utilizing a low dominant vibration frequency of up to 50 Hz (depending on size or up to 100 Hz) for power generation, using a set of fixed and movable permanent magnets 4, 3, 4 The working frequency of the vibration generator is given by the ratio of the generated magnetic stiffness to the mass (moment of inertia) of the entire movable member, so the technical solution of this electromagnetic vibration generator is suitable for low ambient vibrations with frequency up to 50 – 100 Hz, thanks to the soft stiffness characteristic created by a set of repulsive fixed and movable permanent magnets 4, 3. 4. In combination with the mass (or moment of inertia) of the entire moving member of the vibration generator, the required resonant (natural) frequency of the vibration generator, which coincides with the frequency of the excitation vibrations.

If the resilient member is already in use, there is a problem with the relatively large deformation of the resilient member at a low frequency of excited movement. The tuning of the generator at natural frequency dáno is determined by the ratio of stiffness of resilient member to mass of oscillating body. This oscillating motion induces an electromotive voltage in the coil 7, and when the electric load R z is connected to the coil terminals 7, the current passes through the load and the connected electric load R z draws electrical power. When using traditional materials, the use of these design variants for low frequencies is completely inappropriate. Dolor muscular en gemelos . One or more permanent magnets, preferably when rare earth magnets (eg FeNdB) are used. The oscillating body is positioned between a set of repulsive permanent magnets that create the stiffness of the mechanism. It follows that for low vibration frequencies the required vibration deflection value is considerably greater, and therefore sufficient excited movement of the resonance mechanism and sufficient change of the magnetic flux in the coil in the electromagnetic vibration generator can be achieved.

However, the mechanical stop of the excitation circuit 8 with respect to the frame 1 must be engaged due to the overload of peaks at very high acceleration, where this magnetic force can be overcome and would result in impact of some functional parts of the vibration generator. This electromagnetic generator can also generally be used to obtain electrical energy from a general oscillating motion. Coil parameters 7, the diameter of the conductor used and the number of coil turns; together with the magnitude of the resistive load, they significantly influence electromagnetic shielding. The total power generated depends on the ratio of these damping and is maximal if the instantaneous value of the electromagnetic damping given by the design of the excitation circuit, the coil and the loads is equal to the instantaneous value of the mechanical damping depending on the design of the resonant mechanism and the magnitude of the excited movement.

Due to the suitable design of the excitation circuit 8 and the coil 7, the relative excited movement causes a sufficient time change of the magnetic flux by the coil winding and the limiting induces an electromotive voltage in the coil winding. The exact design of the parameters of the whole structure and the structure of the barrel of the excitation circuit 8 and the coil 7 must coincide with the design of all members of the vibration generator, since the individual parameters of the vibration generator are in mutual interaction. One of the preferred designs of the excitation circuit 8 and the coil 7 is shown in Fig.

Due to this design, the excitation circuit 8 does not impinge on the frame 1 and / or the coil 7, this impact would be destructive in nature to the function of the vibration generator, with a brief increase in vibration amplitude, which is very common in real technical systems.
