<p>A device for a linear actuator, including a mobile assembly (1) moving relative to a stator (2) in a travelling direction (D). The assembly (1) includes an excitation winding (3) and an armature comprising pole pieces (Sa, Sb, Sc) and permanent magnets (Aab, Abc). The stator (2) is a simple guide tube defining the path of the mobile assembly (1), and may be made from a profiled ferromagnetic material, with holes (T1, T2) extending through two walls thereof to define stator poles (R1a, R2a, R2b) in two rows mutually longitudinally offset by a half pitch.</p> |
