Abstract

L'invention porte sur une machine électrique tournante qui comprend un noyau ferreux ayant une structure qui ne demande ni déformation ni collage et qui peut être fabriquée avec une faible perte de fer et un haut rendement et à un coût réduit. Une machine électrique tournante comprenant un stator et un rotor, où une dent de stator qui constitue le stator est munie d'un noyau ferreux (31), d'un fil électrique disposé autour du noyau ferreux (31) et d'un isolateur disposé entre le noyau ferreux (31) et le fil électrique, et le noyau ferreux (31) est formé en stratifiant des tôles minces en forme de plaques plates rectangulaires (2), chacune formée en découpant des matières à magnétisme doux (1) en forme de plaque mince dans une largeur prédéterminée (B), une à une ou en plusieurs petits nombres de tôles.
