ABSTRACT:
An angular single-phased electromagnetic actuator including a stator structure constituted of a first magnetic stator part and a second magnetic stator part connected exclusively by a non-magnetic spacer. A movable member including a thin magnetized portion is provided within an air gap between the stator parts. Stator parts are selected so as that: ##EQU1## where, S.sub.fer is the section of the stator part as measured in any radial plane included in the area scanned by the movable radial plane defined by the radius between the two adjacent poles of the magnetized portions,
