Abstract

L’invention concerne un transformateur rotatif triphasé (202) comprenant une première, une deuxième et une troisième bobine primaire (211, 212, 213) associées à respectivement une première, une deuxième et une troisième bobine secondaire (221, 222, 223). Les deuxièmes bobines primaire (212) et secondaire (222) comprenant chacune une première et une deuxième sous-bobine (212A, 212B, 222A, 222B). Chacune des première et troisième bobines (211, 213, 221, 223) étant logée avec une sous-bobine (212A, 212B, 222A, 222B) respective de la deuxième bobine (212, 222) dans respectivement un premier et un deuxième logement (231A, 231B, 232A, 232B, 241A, 241B, 242A, 242B) d’une encoche (231, 232, 241, 242) d’un corps magnétique (230, 240). Pour chaque encoche (231, 232, 241, 242), le logement (231A, 232A, 241A, 242A) correspondant à une sous-bobine (212A, 212B, 222A, 222B) présente une dimension axiale (LA) supérieure à une dimension axiale (LB) du logement (231B, 232B, 241B, 242B) correspondant à la bobine (211, 213, 221, 223) correspondante.
