Abstract

L'éolienne est équipée d'un disque générateur à entrefer axial, de grand diamètre, auto-excité par aimants permanents et dont l'induit ne contient pas de fer. The wind turbine is equipped with an axial gap disk generator of large diameter, self-excited by permanent magnets which the armature does not contain iron. Grace à l'absence de fer dans l'induit, le couple ne nésistant pas au démarrage est très faible, ce qui ne nécessite pas un calage important au démarrage. Thanks to the lack of iron in the armature, the couple does not nésistant start is very low, which does not require a large stall at startup. Cette éolienne peut etre dépourvue d'un système mécanique d'orientation centrifuge des pales. This wind turbine can be devoid of a mechanical system of centrifugal orientation of the blades.

Description


    <EMI ID=1.1> <EMI ID = 1.1> 

  
 d'un générateur à entrefer axial ne contenant pas de fer dans l'induit. an axial gap generator containing no iron in the armature.

  
 1. L'éolienne est équipée d'un disque générateur à 1. The wind turbine is equipped with a generator disk

  
 entrefer axial, de grand diamètre, auto-excité par aimants permanents et dont l'induit ne contient pas de fer. axial airgap, large diameter self-excited by permanent magnets which the armature does not contain iron.  Cette disposition procure les avantages suivants : This arrangement provides the following advantages:
 1.1. 1.1.  Grâce au grand diamètre du générateur, les pales sont fixées directement sur le générateur sans intermédiaire (pas de multiplicateur de vitesse). Thanks to the large diameter of the generator, the blades are attached directly to the generator without intermediate (no speed multiplier).
 1.2. 1.2.  Grâce à l'absence de fer dans l'induit, le couple résistant au démarrage est très faible, ce qui ne nécessite pas un calage important au démarrage. Due to the lack of iron in the armature resistive starting torque is very low, which does not require a large stall at startup.
 1.3. 1.3.  Grâce à la forme de disque plat de l'induit, la caractéristique de refroidissement favorable de l'induit permet un freinage énergique de l'éolienne sans échauffement excessif des bobinages. Thanks to the shape of flat armature disc, the favorable cooling characteristic of the armature permits a strong braking of the wind turbine without excessive heating of the windings.  Cette disposition permet la suppression de la mise en drapeau des pales, ou de l'éolienne complète, par grand vent. This arrangement allows the suppression of feathering the blades, or the complete wind turbine in high winds.
 1.4. 1.4.

    Grâce aux avantages évoqués aux points 1.2. Thanks to the advantages mentioned in 1.2.  et and
 1.3., l'éolienne peut être dépourvue d'un système mécanique d'orientation centrifuge des pales. 1.3., The wind turbine can be devoid of a mechanical system centrifugal orientation of the blades.
