Abstract
L'invention concerne un rotor (200) cylindrique à champ radial, prévu pour être disposé dans un stator, comprenant au moins deux logements (206), dits longitudinaux prévus pour recevoir au moins un aimant (208), et se prolongeant dans la direction axiale (102) dudit rotor (200), chaque logement longitudinal étant non-débouchant à la surface extérieure (104) dans la direction radiale ; caractérisé en ce que au moins un, en particulier chaque, logement longitudinal (206) est séparé d'un logement longitudinal adjacent (206) par une paroi (210), dite jante, présentant une épaisseur : - supérieure ou égale à 0,1mm ; et - inférieure ou égale à 25% du diamètre extérieur dudit rotor (200). Elle concerne également une machine électrique et/ou magnétique mettant en œuvre un tel rotor.The invention relates to a cylindrical rotor (200) with a radial field, intended to be arranged in a stator, comprising at least two housings (206), said longitudinal designed to receive at least one magnet (208), and extending in the direction axial (102) of said rotor (200), each longitudinal housing being non-opening at the outer surface (104) in the radial direction; characterized in that at least one, in particular each, longitudinal housing (206) is separated from an adjacent longitudinal housing (206) by a wall (210), called a rim, having a thickness: - greater than or equal to 0.1 mm ; and - less than or equal to 25% of the outside diameter of said rotor (200). It also relates to an electric and / or magnetic machine implementing such a rotor.
