Title
(EN) ROTATING ARMATURE FOR A WIND TURBINE GENERATOR HAVING A SUPERCONDUCTING STATOR
(FR) INDUIT ROTATIF DESTINÉ À UN GÉNÉRATEUR D'ÉOLIENNE COMPORTANT UN STATOR SUPRACONDUCTEUR
Abstract
(EN)
An armature is presented. The armature includes an armature winding having a plurality of coils, wherein each coil of the plurality of coils is spaced apart from adjacent coils and comprise includes a first side portion and a second side portion. The armature further includes a first electrically insulating winding enclosure. Furthermore, the armature includes a second electrically insulating winding enclosure disposed at a radial distance irom the first electrically insulating winding enclosure, wherein the armature winding is disposed between the first electrically insulating winding enclosure and the second electrically insulating winding enclosure. Moreover, the armature includes an electrically insulating coil side separator disposed between the first side portion and the second side portion of the piuraiity of coils of the armature winding. A superconducting generator including the armature and a wind turbine having such superconducting generator are also presented.

La présente invention concerne un induit. L'induit comprend un enroulement d'induit ayant une pluralité de bobines, chaque bobine de la pluralité de bobines étant espacée des bobines adjacentes et comprenant une première partie latérale et une seconde partie latérale. L'induit comprend en outre une première enceinte d'enroulement électriquement isolante. En outre, l'induit comprend une seconde enceinte d'enroulement électriquement isolante disposée à une distance radiale de la première enceinte d'enroulement électriquement isolante, l'enroulement d'induit étant disposé entre la première enceinte d'enroulement électriquement isolante et la seconde enceinte d'enroulement électriquement isolante. De plus, l'induit comprend un séparateur latéral de bobine électriquement isolant disposé entre la première partie latérale et la seconde partie latérale de la pluralités de bobines de l'enroulement d'induit. L'invention concerne également un générateur supraconducteur comprenant l'induit et une éolienne comportant ce générateur supraconducteur.
