The reference to the longitudinal axis of the first part generally refers to the longitudinal axis when the first part is not oscillating. Obviously, there is no direct relation between the mass of the first part as such and its inertia, as the first part is not moving linearly but rather carries out a pivoting or pendulum- like movement in relation to a certain point, wherefore its inertia has a substantial rotary component. Said at least one first magnet and said at least one second magnet are arranged in such a way that they repel each other and in such a way that when the oscillating movement occurs in the first part, the distance between said at least one first magnet and said at least one second magnet varies in accordance with said oscillating movement. In some embodiments of the invention, the displacing magnets and the displaced magnets have an at least partially spherical shape, and in other embodiments they have an elongated shape and extend in a radial direction relative to the longitudinal axis of the first part.

Figure 4 shows, schematically, how the magnets 30 are mounted on a support structure 13 mounted on the flexible part 12 and how the coils 50 are mounted on the static structure 2 itself (see also figure 5). It would also be possible to mount the coils 50 on the pole, but from the practical point of view it may be preferable to mount them on the fixed portion to facilitate the connection to the external network to which the generated power is intended to be transmitted, thereby reducing the risk of fatigue rupture of the conductors evacuating the energy and avoiding unnecessary viscous losses. Figures 1 and 4 show how in this embodiment of the invention the static structure 2 comprises a substantially cylindrical wall 21 which surrounds the pole 1 in correspondence with its bottom part.

Figure 4 shows how the magnets are mounted on a total of five rows, of which the four top rows contribute to the electrical power generation owing to their interaction with the coils 50, while both the four top rows and the bottom row contribute to the auto-tuning of the generator to wind speed. As wind speed increases and it approaches the speed at which the frequency of appearance of vortices coincides with the natural oscillation frequency of the structure, the amplitude of the oscillation of the pole increases, until reaching a maximum. On the other hand, as is known, when a force of oscillation is applied to an element or object, the corresponding energy is absorbed better if the force that is applied oscillates at a frequency that corresponds to the natural oscillation frequency of the object in question. Also, as the velocity of the oscillator movement in terms of velocity of displacement of the first part is at its maximum when reaching the neutral or center position, arranging for triggering to take place at this moment enhances the impulse-like character of the triggering and transfer of energy and momentum.
The rotor is provided with magnets that rotate with the rotor and which interact with magnets coupled to piezoelectric elements such that the rotation of the rotor results in a force on the piezoelectric elements, such that the rotation of the rotor is converted into electrical energy. The difference in mass can be related to a difference in inertia, which influences the possibility to use the oscillatory movement of the first part at a first frequency to trigger and maintain the movement of the second generator module at a second frequency higher than the first frequency. As the repulsion force between the two magnets is inversely proportional to the square of the distance between the magnets, the force will vary substantially during the oscillation of the first part and its maximum value may depend significantly on the amplitude of the oscillatory movement.
The generator also comprises a second part that surrounds, at least partially, the first part. In some embodiments this arrangement may also be useful to facilitate a concentration of the elements of the generator close to a longitudinal axis of the generator, minimizing its extension or dimension in the lateral direction. This arrangement serves to enhance the efficiency of the magnets in terms of their contribution to the increase of the resonance frequency of the first part when the speed of the fluid increases, and vice-versa. In some embodiments of the invention, the first part will have a height of at least 1 meter, for example, more than 2, 5, 10, 15, 60, 100, or 200 meters. In some embodiments of the invention, the second generator module is connected to the first generator module by means of a plurality of connecting members arranged to allow for movement of the second generator module in parallel with the longitudinal axis of the first part, and to prevent the second generator module from contacting the first generator module.

The second part can surround the first part, at least partly, in correspondence with said base, such that when the oscillating movement of the first part with respect to the base is produced, the first part, for example, the flexible part of the first part, may be tilted alternately to one side of the second part and to the other side of the second part, approaching one side and then the other side of the second part. This can, for example, be achieved by letting the displacing magnets approach the displaced magnets with a movement substantially perpendicular to the direction of the movement of the second generator, whereby the component of the repulsive force in the direction parallel with the direction of the movement of the second generator module increases rapidly. The connecting members can be substantially resistant to elongation, whereby, if appropriately arranged, it can be ensured that the second generator module can only move in parallel with the longitudinal axis of the first part, such as vertically, but not laterally.

Therefore, when the first part oscillates the coils can move between said two sets of magnets and are subjected to repeated changes of polarity or direction of the magnetic field, owing to the polarity alternation defined by the magnet rings. In some embodiments of the invention, the second generator module is biased in a first direction by first biasing means, such as by first biasing means comprising magnets and/or springs, the first direction being parallel with the longitudinal axis of the first part. In some embodiments of the invention, the subsystem of magnets comprises at least two sets of magnets arranged at different heights above a base of the generator, each set of magnets comprising a plurality of magnet rings arranged coaxially around the first part and such that a magnetic field is established between said sets of magnets having, radially, at least one change of direction, preferably at least two changes of direction, more preferably at least four changes of direction.

In some embodiments of the invention, the generator comprises a generator or alternator subsystem comprising a first generator module and a second generator module moveable in relation to said first generator module in parallel with a longitudinal axis of the first part (such as a pole), to produce the relative displacement between the magnet or subsystem of magnets and the at least one coil. Thus, oscillation of the first part in relation to a vertical axis is arranged to trigger the second generator module to oscillate up and down. In other words, a function of the magnets 30 and 40 may be to obtain the automatic tuning between the natural oscillation frequency of the pole and the frequency of appearance of vortices. Faja para dolor de espalda . However, a substantial part of the flexible part 12 is free and able to oscillate, together with the rigid part 1 1 towards one side and the other, owing to the aforementioned lift force.
It can also be useful to facilitate implementation of a second generator module oscillating at a frequency different from the frequency of oscillation of the first part. In some embodiments of the invention, the displacing magnets are arranged around and at a distance from the longitudinal axis of the first part, so as to interact with corresponding ones of the displaced magnets during oscillation of the first part, thereby repetitively transferring momentum from the first part to the second generator module. Figure 1 6D schematically illustrates an embodiment like the one of figure 1 6C, with the difference that each ring of magnets has a heighT corresponding to only one magnet. However, as a rule of thumb, a substantial difference in mass, for example, in line with the percentages indicated above, can be beneficial so as to allow for the second generator module to oscillate at a frequency higher than the frequency of oscillation of the first part.
The rigid top part has a characteristic dimension (the diameter in the case of a circular cross section) that varies depending on a height “Y” on the attachment point of the flexible bottom part to the base. Given that the velocity of the air increases with height, according to the Hellmann exponential Law, to achieve synchronisation in the appearance of vortices, WO-2012/017106-A1 proposes an increase in pole diameter with the increase of height. In this way, the very structure of the generator of figures 1 and 4, with its magnets 30 and 40, contributes to an automatic increase in the resonance frequency of the pole when the wind speed increases and vice versa. This type of generator based on the Karman vortices can operate without bearings, gears and lubricants and does not require a start system. Figures 1 0A and 1 0B illustrate two simplified models of the behaviour of a pole without any tuning system (figure 10A) and with a tuning system (figure 1 0B), respectively.
In many embodiments of the invention, the first part is oscillating at a relatively low frequency, and it can be desirable to produce the displacement between magnet(s) and coil(s) at a higher frequency, to enhance efficient production of electric power. In some embodiments of the invention, the coils are arranged on the second part and the subsystem of magnets is arranged on the first part. In some of these embodiments, the biasing in the first direction, such as upwards, is at least in part produced by springs and/or magnets. Thus, arranging the second generator module to oscillate at a higher frequency instead of being tied to oscillate at the frequency of oscillation of the first part, has been considered to be advantageous.

As illustrated in figure 4, the coils 50 are distributed in three levels, i.e., at three different heights above the base of the generator. Another aspect of the invention relates to a method for making an electrical power generator tune with wind speed. In some embodiments of the invention, this direction is upwards.
