Abstract

MOTEUR COUPLE À GAIN VARIABLE L’invention concerne un moteur couple configuré pour permettre le positionnement d’un mobile, comprenant une armature (16) configurée pour pouvoir être entrainée en rotation autour d’une direction (18) axiale en cas d’alimentation d’au moins une bobine (22a, 22b) par un courant électrique par application d’un couple électro-magnétique, ladite armature (16) s’étendant selon une direction sensiblement perpendiculaire à la direction axiale et étant agencée entre deux masses (14a, 14b) polaires reliées par un aimant (12a, 12b) permanent, l’armature (16) étant reliée à un tube de torsion permettant l’application d’un couple résistant principal à l’armature (16) s’opposant au couple électro-magnétique, caractérisé en ce que le moteur couple comprend en outre au moins un ressort (24a, 24b) configuré pour appliquer un couple résistant supplémentaire à l’armature (16) s’opposant au couple électro-magnétique lorsque l’angle de rotation de l’armature (16) par rapport à une position neutre est supérieur à un premier angle de rotation prédéterminé. Figure pour l’abrégé : figure 1bThe invention relates to a torque motor configured to allow the positioning of a mobile, comprising an armature (16) configured to be able to be driven in rotation around an axial direction (18) in the event of power supply. at least one coil (22a, 22b) by an electric current by application of an electromagnetic torque, said armature (16) extending in a direction substantially perpendicular to the axial direction and being arranged between two masses (14a, 14b) poles connected by a permanent magnet (12a, 12b), the armature (16) being connected to a torsion tube allowing the application of a main resistive torque to the armature (16) opposing the electro torque -magnetic, characterized in that the torque motor further comprises at least one spring (24a, 24b) configured to apply an additional resistant torque to the armature (16) opposing the electromagnetic torque when the angle of rotation of the armature (16) relative at a neutral position is greater than a first predetermined angle of rotation.
