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. 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. Cette éolienne peut etre dépourvue d'un système mécanique d'orientation centrifuge des pales.The wind turbine is equipped with a generator disc with axial air gap, of large diameter, self-excited by permanent magnets and whose armature does not contain iron. Thanks to the absence of iron in the armature, the torque which does not exist at start-up is very low, which does not require significant setting at start-up. This wind turbine can be devoid of a mechanical system for centrifugal orientation of the blades.
Description
<EMI ID=1.1>
d'un générateur à entrefer axial ne contenant pas de fer dans l'induit.
1. 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. Cette disposition procure les avantages suivants :
1.1. Grâce au grand diamètre du générateur, les pales sont fixées directement sur le générateur sans intermédiaire (pas de multiplicateur de vitesse).
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.
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. Cette disposition permet la suppression de la mise en drapeau des pales, ou de l'éolienne complète, par grand vent.
1.4.
Grâce aux avantages évoqués aux points 1.2. et
1.3., l'éolienne peut être dépourvue d'un système mécanique d'orientation centrifuge des pales.
<EMI ID = 1.1>
of an axial air gap generator not containing iron in the armature.
1. The wind turbine is equipped with a generator disc
axial air gap, large diameter, self-excited by permanent magnets and whose armature does not contain iron. This arrangement provides the following advantages:
1.1. Thanks to the large diameter of the generator, the blades are fixed directly to the generator without any intermediary (no speed multiplier).
1.2. Thanks to the absence of iron in the armature, the torque resistant to start-up is very low, which does not require significant stalling at start-up.
1.3. Thanks to the flat disc shape of the armature, the favorable cooling characteristic of the armature allows vigorous braking of the wind turbine without excessive heating of the windings. This arrangement eliminates the feathering of the blades, or the complete wind turbine, in high winds.
1.4.
Thanks to the advantages mentioned in points 1.2. and
1.3., The wind turbine can be devoid of a mechanical system for centrifugal orientation of the blades.
