Title (EN) ELECTRIC ACTUATOR
(FR) ACTIONNEUR ÉLECTRIQUE
Abstract:
(EN) An electric actuator assembly (20) having a support housing (28, 124), a first stator magnetic field generating assembly (26) secured to the support housing (28, 124) and a movable armature assembly (22). The movable armature assembly (22) includes a plate assembly having a center support (150). The electric actuator assembly also includes a first armature magnetic field generating assembly configured to provide magnetic fields operative with a first stator magnetic field generating assembly to provide linear motion of the movable armature assembly (22) along a reference axis, the first armature magnetic field generating assembly including first and second magnetic assemblies secured to opposite sides of the center support. In another embodiment, the electric linear actuator (20) includes a rotational component (27) coupled to a linear component (25) to move therewith. The rotational component (27) includes an armature magnetic field generating assembly being one of longer or shorter than a stator magnetic field generating assembly.
(FR) Un ensemble actionneur électrique (20) comprend un boîtier de support (28, 124), un premier ensemble de génération de champ magnétique de stator (26) fixé au boîtier de support (28, 124) et un ensemble induit mobile (22). L'ensemble induit mobile (22) comprend un ensemble plaque ayant un support central (150). L'ensemble actionneur électrique comprend également un premier ensemble de génération de champ magnétique d'induit configuré pour fournir des champs magnétiques fonctionnels avec un premier ensemble de génération de champ magnétique de stator en vue de fournir un mouvement linéaire de l'ensemble induit mobile (22) le long d'un axe de référence, le premier ensemble de génération de champ magnétique d'induit comprenant des premier et second ensembles magnétiques fixés sur des côtés opposés du support central. Selon un autre mode de réalisation, l'actionneur linéaire électrique (20) comprend un composant rotatif (27) couplé à un composant linéaire (25) pour se déplacer avec celui-ci. Le composant rotatif (27) comprend un ensemble de génération de champ magnétique d'induit qui est plus long ou plus court qu'un ensemble de génération de champ magnétique de stator.
