Abstract

La présente invention concerne une machine électrique sans balais à rotor à aimant permanent intérieur. Ledit rotor est constitué par un noyau tubulaire (1) d'une section extérieure D ext et d'une section intérieur Dint avec Dext/Dint compris entre 1,3 et 1,4, ledit noyau (1) présentant N paires de logements longitudinaux (2, 3) à section transversale trapézoïdale, d'une largeur La et d'une longueur L, avec La/L compris entre 0,25 et 0,35, les deux logements (2, 3) d'une paire s'étendant de part et d'autre du plan radial médian, avec un angle de 7,5° +/- 1,5°, ledit noyau présentant dans la zone de convergence de chaque paire de logements un canal longitudinal (10) débouchant de part et d'autre des extrémités frontales du noyau (1).
