Abstract

L'invention concerne une machine électrique sans balais à rotor à aimant permanent intérieur. Ledit rotor est constitué par un noyau tubulaire (1) présentant des logements longitudinaux pour l'insertion d'aimants permanents (21 à 28), la section dudit noyau présentant une couronne annulaire (1) au moins partiellement amagnétique prolongée par des pétales (2 à 11) ferromagnétiques doux définissant entre eux lesdits logements pour l'insertion et le maintien des aimants permanents (21 à 28).
