Beschreibung
Zusammenfassung:	The actuator (11) has a mobile part (22) with a ferromagnetic element (23) having air gap surfaces (35, 38) respectively forming a variable thickness magnetic air gap (34) and a constant thickness residual magnetic air gap (36). A magnetized assembly of a fixed part (12) is mounted against the surface (38) such that the air gap (36) is formed between the surface (38) and an air gap surface corresponding to the assembly. Magnets (31, 32) of the assembly are mounted on a face (33) of a ferromagnetic yoke (13) and extend on the face's dimension parallel to a displacement axis (26) of the face.
