Abstract (en)
[origin: ES486095A1] Magnetic actuator apparatus in which the armature is held in a restrained position on a magnetic core by magnetic flux whose density is cyclically varied in time, and the armature is selectively released by a bucking coil that is energized only when the armature retention flux is at low holding value. The flux source is a permanent magnet that is reciprocated or rotated to vary the armature retaining force.
