Abstract

The invention concerns a generator comprising: 1) a flywheel magneto integrated in the turbine whereof the rim laterally supports the magnetising poles, not requiring rotation speed increasing gears or unit; 2) a partial armature for modifying the air gap size, thereby modifying the voltage; 3) an armature with coils offset at an angle cancelling the longitudinal attraction of the poles when facing each other at rest; 4) optionally an inductor with its poles angularly offset; 5) optionally a number of different poles for the inductor and the armature. The voltage is regulated by variable mutual coupling of the coils.

Description

L'énergie des éoliennes doit être transportée à distance pour pouvoir être utilisée sur les lieux d'activité. Energy from wind turbines must be transported remotely in order to be used at places of activity.

La manière la plus commode est l'électricité, produite par des alternateurs ou des dynamos.The most convenient way is electricity, produced by alternators or dynamos.

La faible vitesse de rotation des éoliennes habituelles oblige à multiplier celle-ci au moyen d'engrenages, ou de poulies et courroies, pour ne pas devoir construire des génératrices énormes, coûteuses et d'usage incommode. The low speed of rotation of conventional wind turbines means that it must be multiplied by means of gears, or pulleys and belts, so as not to have to build huge, expensive generators and inconvenient use.

Il est pourtant possible d'en réduire fortement les dimensions et le prix dans le cas des turbines plates ou coniques, en utilisant leur structure, c'est-à-dire la jante réunissant les pales. On peut transformer ces jantes en volants magnétiques, en garnissant leur périphérie d'aimants permanents ou bobinés, la vitesse périphérique des jantes étant comparable à celle des rotors des génératrices de même puissance. L'induit (C-Figure 1) est fixé au châssis de la turbine. L'inducteur-jante 3 (Figures 1 et 2) tourne. On peut en diminuer l'encombrement et le poids en ne conservant qu'une partie de l'induit (1-Figure 1), ce qui exige une augmentation de la surface des pôles restants, à puissance égale. Ce procédé n'est pas nouveau puisqu'en 1920 déjà, le brevet USA nO 1352960, et en 1968, le brevet de la GB nO 1253364 l'utilisaient. Cela permet de supprimer les enroulements là où ils sont le plus en danger, au haut des éoliennes, tout en diminuant le nombre des pôles à bobine, donc aussi le nombre de chignons (2-Figure 2), d'où une économie de cuivre. Cette amputation de la culasse rend possible le réglage de l'entrefer, cet induit partiel pouvant pivoter autour d'un axe fixe (O-Figure 4) sans perturber le mouvement du rotor (3-Figure 2). It is however possible to greatly reduce the dimensions and the price in the case of flat or conical turbines, by using their structure, that is to say the rim joining the blades. These rims can be transformed into magnetic flywheels, by lining their periphery with permanent or wound magnets, the peripheral speed of the rims being comparable to that of the rotors of generators of the same power. The armature (C-Figure 1) is attached to the turbine frame. The rim inductor 3 (Figures 1 and 2) rotates. We can reduce its size and weight by keeping only part of the armature (1-Figure 1), which requires an increase in the surface of the remaining poles, at equal power. This process is not new since in 1920 already, the US patent n ° 1352960, and in 1968, the patent of the GB nO 1253364 used it. This eliminates the windings where they are most at risk, at the top of the wind turbines, while reducing the number of coil poles, therefore also the number of chignon (2-Figure 2), hence saving copper . This amputation of the cylinder head makes it possible to adjust the air gap, this partial armature being able to pivot around a fixed axis (O-Figure 4) without disturbing the movement of the rotor (3-Figure 2).

Ce mouvement limité est commandé par une bielle (7-Figure 4), et une tige filetée (6) mue par un servomoteur (8-Figure 4). Le mouvement de la culasse est guidé par des glissières ne figurant pas sur le dessin par souci de clarté, et sert à régler la tension électrique, ou à corriger un jeu éventuel. This limited movement is controlled by a connecting rod (7-Figure 4), and a threaded rod (6) driven by a servomotor (8-Figure 4). The movement of the cylinder head is guided by slides not shown in the drawing for the sake of clarity, and is used to adjust the electrical tension, or to correct any play.

La situation des pôles inducteurs à la périphérie de la jante les soumet à une force centrifuge qui s'ajoute à l'attraction magnétique de la culasse, à laquelle la colle qui les fixe doit résister. The location of the inductor poles at the periphery of the rim subjects them to a centrifugal force which is added to the magnetic attraction of the cylinder head, to which the glue which fixes them must resist.

On peut diminuer cette fatigue en fixant les aimants ou pôles latéralement à la jante, du côté d'où vient le vent (9-Figure 5). On les bloque au moyen d'une bordure extérieure (10-Figure 5). Le réglage de l'entrefer est plus régulier, ses deux côtés restant parallèles. Ce réglage ne serait pas possible avec une double rangée de pôles de chaque côté de la jante, l'espace 13 augmentant si l'entrefer 14 (Figure 6) diminue. This fatigue can be reduced by fixing the magnets or poles laterally to the rim, on the side from which the wind comes (9-Figure 5). They are blocked by means of an external border (10-Figure 5). The adjustment of the air gap is more regular, its two sides remaining parallel. This adjustment would not be possible with a double row of poles on each side of the rim, the space 13 increasing if the air gap 14 (Figure 6) decreases.

Pour éviter un démarrage difficile des volants magnétiques, dû à la permanence du flux magnétique des aimants, on peut incliner d'un angle a les bobines ou les aimants de l'inducteur par rapport à leur position normale (5
Figure 3), ou incliner les bobines de l'induit (11-Figure 7), par rapport à leur position normale (12-Figure 7).To avoid difficult starting of the magnetic flywheels, due to the permanence of the magnetic flux of the magnets, the coils or the magnets of the inductor can be tilted at an angle relative to their normal position (5
Figure 3), or tilt the armature coils (11-Figure 7), relative to their normal position (12-Figure 7).

L'attraction mutuelle des pôles inducteurs qui se font face à l'arrêt est ainsi annulée. On peut aussi, plus simplement avoir un nombre de pôles inducteurs différent de celui de 1' induit. The mutual attraction of the inducing poles which face the stop is thus canceled. It is also possible, more simply, to have a different number of inducing poles than that of the armature.

Pour ne pas laisser tourner les roues éoliennes par vent trop faible, on peut ne pas compenser totalement les attractions entre pôles, pour démarrer seulement à partir d'une certaine vitesse du vent. In order not to let the wind wheels turn in too weak wind, it is not possible to completely compensate the attractions between poles, to start only from a certain wind speed.

La fixation des inducteurs latéralement à la jante, d'un seul côté de la turbine, et perpendiculairement à l'axe de celle-ci, face au vent, procure les avantages suivants 1) Régler l'entrefer est possible, et celui-ci peut être fai
ble, ce qui est difficile avec un entrefer double (en U,
figure 6).Attaching the inductors laterally to the rim, on one side of the turbine, and perpendicular to the axis thereof, facing the wind, provides the following advantages 1) Adjust the air gap is possible, and the latter maybe be
ble, which is difficult with a double air gap (in U,
figure 6).

2) Ce réglage permet de stabiliser la tension électrique en
faisant varier le flux magnétique, sans enroulement magné
tisant (Figures 4 et 5).2) This setting stabilizes the electrical voltage by
varying the magnetic flux, without magnet winding
waking (Figures 4 and 5).

3) La poussée du vent tend à éloigner la turbine de l'induit,
en cas de rafales anormalement fortes, ce qui favorise la
sécurité. 3) The thrust of the wind tends to move the turbine away from the armature,
abnormally strong gusts, which promotes
security.

4) Cette disposition évite les amas de feuilles et matières
étrangères toujours possibles dans le cas d'un entrefer en
U.4) This provision avoids clumps of leaves and materials
always possible in the case of an air gap in
U.

Stabilisation de la tension électrique
La variation de la largeur de l'entrefer ne suffit pas toujours à maintenir la constance de la tension électrique. Quand le vent varie beaucoup, il faut agir sur le couplage des bobines induites. A basse vitesse, elles sont toutes branchées en série. Si la vitesse augmente trop, les bobines 15, 16 etc.. de la figure 8 sont successivement débranchées, ce qui ramène la tension à sa valeur normale.Electric voltage stabilization
The variation in the width of the air gap is not always sufficient to maintain the constancy of the electrical voltage. When the wind varies a lot, it is necessary to act on the coupling of the induced coils. At low speed, they are all connected in series. If the speed increases too much, the coils 15, 16 etc. of FIG. 8 are successively disconnected, which brings the voltage back to its normal value.

Quand le nombre des bobines débranchées atteint la moitié du total des bobines induites, elles sont reconnectées en parallèle avec les bobines restantes (Figure 10), ce qui réduit la résistance interne du générateur, et augmente sa puissance potentielle, l'échauffement des bobines diminuant de moitié.When the number of the disconnected coils reaches half of the total of the induced coils, they are reconnected in parallel with the remaining coils (Figure 10), which reduces the internal resistance of the generator, and increases its potential power, the heating of the coils decreasing A half.

En cas de nouvelle accélération de l'inducteur, on reprend le processus initial, en débranchant successivement des fractions de bobines 20, 21, etc.. (Figure 11). La combinaison de la variation de l'entrefer avec la mise hors service temporaire de fractions de bobines permet de ramener la tension de service dans la fourchette des tolérances industrielles (par exemple E + ou - 10 %).In the event of further acceleration of the inductor, the initial process is resumed, by successively disconnecting fractions of coils 20, 21, etc. (Figure 11). The combination of the variation in the air gap with the temporary deactivation of coil fractions allows the operating voltage to be brought back within the range of industrial tolerances (for example E + or - 10%).

Variante de ce système
Les bobines induites peuvent aussi avoir une section de cuivre croissant de 15 à 18 (Figure 8), tout en utilisant les couplages précédents. Ce qui précède n'exclut pas l'utilisation du hachage, méthode qui consiste à interrompre le courant un grand nombre de fois par seconde pour provoquer une chute de tension. Ce hachage est produit par un semiconducteur (Thyristor ou autre), 22, Figure 12, en série avec les bobines. Variant of this system
Induced coils can also have a growing copper section from 15 to 18 (Figure 8), while using the previous couplings. The above does not exclude the use of hashing, a method which consists in interrupting the current a large number of times per second to cause a voltage drop. This chopping is produced by a semiconductor (Thyristor or other), 22, Figure 12, in series with the coils.
