Abstract
A DC electromagnet system used in an electrical switchgear, for example in a contactor having a driving coil, includes a fixed, C-shaped magnet yoke and a movable, rod-shaped armature. The yoke has a central web and two legs. The armature is guided in its displacement stroke by guide devices, the free end of the armature being directed toward the central web of the magnet yoke. There is a single working air gap between the free end of the armature and the center of the central web, perpendicular to the longitudinal axis of the armature. The ends of the yoke legs extend to the proximity of the armature and are separated from the armature, each forming a parasitic air gap.
