Abstract
An electric actuator assembly having a support housing, a first stator magnetic field generating assembly secured to the support housing and a movable armature assembly. The movable armature assembly includes a plate assembly having a center support. 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 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 includes a rotational component coupled to a linear component to move therewith. The rotational component includes an armature magnetic field generating assembly being one of longer or shorter than a stator magnetic field generating assembly.
