Abstract

Cette machine électrique synchrone (2) comprend un rotor (1) mobile en rotation autour d’un axe longitudinal (X) et comportant une pluralité d’aimants permanents formant des pôles (P1,…, P4) répartis à la périphérie du rotor (1), un stator (3) disposé autour du rotor (1) et comportant des dents (13) sur lesquelles sont disposées des bobines (6). Elle comporte un entrefer disposé entre le rotor (1) dont l’épaisseur radiale déterminée selon un axe transversal (Y) perpendiculaire à l’axe longitudinal (X) varie suivant l’axe longitudinal (X).
