Abstract
(EN) The present invention relates to a stator of an axial-flux electric machine (1) comprising a casing (2) and an active core including a plurality of wound cores (9) arranged in a support disk (11), the support disk (11) comprising a plurality of peripheral notches (14) spaced apart along an outer periphery of the disk (11), with each peripheral notch (14) having an engagement portion (17) formed on the open end (15) thereof and designed to cooperate with a corresponding engagement portion (18) formed in the inner surface of the casing (2).
(FR) La présente invention concerne un stator d'une machine électrique à flux axial (1) comprenant un châssis (2) et un noyau actif comportant une pluralité de noyaux bobinés (9) disposés sur un disque de support (11), le disque de support (11) comportant une pluralité d'évidements périphériques (14) qui s'étendent de manière espacée sur une périphérie extérieure du disque (11), chacun des évidements périphériques (14) possédant une partie d'accouplement (17) formée au niveau de son extrémité ouverte (15) et conçue pour coopérer avec une partie d'accouplement (18) correspondante formée sur la surface intérieure du châssis (2).
(PT) A presente invenção refere-se a um estator de uma máquina elétrica de fluxo axial (1) compreendendo uma carcaça (2) e um núcleo ativo compreendendo uma pluralidade de núcleos bobinados (9) dispostos em um disco de suporte (11), o disco de suporte (11) compreendendo uma pluralidade de recortes periféricos (14) que se estendem de forma espaçada em uma periferia externa do disco (11), cada um dos recortes periféricos (14) possuindo uma porção de encaixe (17), formada em sua extremidade aberta (15), configurada para cooperar com uma porção de encaixe correspondente (18) formada na superfície interna da carcaça (2).
