Abstract

L'invention concerne un moteur (M) électromagnétique à flux magnétique radial destiné à la direction assistée d'un véhicule automobile. Le moteur comporte deux stators (1, la) encadrant un rotor (2) central. Entre chaque stator (1,1a) et une face du rotor (2) se trouve un entrefer (4, 4a). Le rotor (2) comprend un unique aimant (3) s'étendant complètement dans la portion du rotor (2) comprise entre les deux entrefers (4, 4a). Chaque stator (1,1a) porte une série des éléments de bobinage (5, 6, 7, 5a, 6a, 7a) comprendant les dents (7,7a) bobinés, les encoches (6,6a) et un élément de séparation (5, 5a) disposé entre chaque encoche (6, 6a) d'une dent (7, 7a) et l'encoche (6, 6a) de la dent (7, 7a) adjacente et successive. Ainsi, la création d'un couple de détente est réduite.
