Title (EN) TORQUE MOTOR WITH MECHANICAL FLEXURES ESTABLISHING ARMATURE-TO-FIELD GAPS
(FR) MOTEUR-COUPLE À ÉLÉMENTS DE FLEXION MÉCANIQUES ÉTABLISSANT DES ESPACES ENTRE L'ARMATURE ET LE CHAMP
Abstract:
(EN) A torque motor has a mechanical reference member, an armature, and a field assembly. The field assembly includes field pole pieces defining a pole opening, and the armature is mounted to the mechanical reference member for rotation about a motor axis and extends into the pole opening with respective gaps to the field pole pieces. The field assembly is secured to the mechanical reference member and spaced therefrom by elastically deformable flexures, deformed sufficiently to locate the armature at a predetermined position within the pole openings with corresponding lengths of the gaps. During manufacture, a load can be applied to move the field assembly relative to the mechanical reference member against the deformation force of the flexures to locate the pole opening relative to the armature pole piece such that the gaps of desired lengths are formed.
(FR) L'invention concerne un moteur-couple qui comporte un élément de référence mécanique, une armature, et un ensemble champ. L'ensemble champ comprend des pièces polaires de champ définissant une ouverture de pôle, et l'armature est montée sur l'élément de référence mécanique pour une rotation autour d'un axe de moteur et s'étend dans l'ouverture de pôle avec des espaces respectifs par rapport aux pièces polaires de champ. L'ensemble champ est fixé à l'élément de référence mécanique et espacé de celui-ci par des éléments de flexion élastiquement déformables, suffisamment déformés pour situer l'armature en une position prédéfinie dans les ouvertures de pôle avec des longueurs correspondantes des intervalles. Pendant la fabrication, une charge peut être appliquée pour déplacer l'ensemble champ par rapport à l'élément de référence mécanique à l'encontre de la force de déformation des éléments de flexion afin de localiser l'ouverture de pôle par rapport à la pièce polaire de l'armature de telle sorte que les espaces de longueurs souhaitées soient formés.
