Abstract

Le moteur comprend un stator (2), comprenant une pluralité de bobines (4), et un rotor (6) mobile en rotation et solidaire d'un arbre (10), ledit rotor (6) comprenant au moins deux aimants (8) séparés des bobines (4) par un entrefer (23) dont l'épaisseur (e) présente une valeur prédéterminée, chaque aimant (8) s'étendant radialement entre deux faces latérales (26), chaque face latérale (26) s'étendant dans un plan radial passant par le centre du rotor (6), les faces latérales (26) adjacentes des aimants (8) étant séparées par un espace inter-aimant (24) défini par l'angle (alpha) formé entre eux par les plans dans lesquels s'étendent lesdites faces latérales. L'angle (alpha) de l'espace inter-aimant est calculé pour l'épaisseur d'entrefer (e) prédéfinie de sorte à minimiser les ondulations de couple en conservant l'induction générée par les aimants dans l'entrefer (23) à une valeur prédéfinie.
