Title
(EN) STATOR FOR AN ELECTRIC GENERATOR FOR A WIND TURBINE
(FR) STATOR POUR GÉNÉRATEUR ÉLECTRIQUE D'ÉOLIENNE
Abstract
(EN)
It is described a stator (100) for an electric generator (10), in particular for a wind turbine (1). The stator (100) comprising: an inner frame structure (110) having an annular shape formed around a rotational axis (Y) corresponding to an axial direction of the electric generator (10); and an outer frame structure (121, 122) formed around the rotational axis (Y) and surrounding the inner frame structure (110), the outer frame structure (121, 122) being radially distanced from the inner frame structure (110); and a plurality of spokes (150) distributed around the rotational axis (Y) and connecting the inner frame structure (110) and the outer frame structure (121, 122).

L'invention concerne un stator (100) destiné à un générateur électrique (10), en particulier d'éolienne (1). Le stator (100) comprend : une structure de cadre interne (110) ayant une forme annulaire formée autour d'un axe de rotation (Y) correspondant à une direction axiale du générateur électrique (10) ; et une structure de cadre externe (121, 122) formée autour de l'axe de rotation (Y) et entourant la structure de cadre interne (110), la structure de cadre externe (121, 122) étant radialement à distance de la structure de cadre interne (110) ; et plusieurs rayons (150) répartis autour de l'axe de rotation (Y) et reliant la structure de cadre interne (110) et la structure de cadre externe (121, 122).
