Abstract
A device for a linear actuator, including a mobile assembly moving relative to a stator in a traveling direction. The assembly includes an excitation winding and an armature comprising pole pieces and permanent magnets. The stator is a simple guide tube defining the path of the mobile assembly, and may be made from a profiled ferromagnetic material, with holes extending through two walls thereof to define stator poles in two rows mutually longitudinally offset by a half pitch.
