Abstract
The invention relates to a linear magnetic drive consisting of an iron core and a coil. A yoke and a constant magnet are connected to a movable armature. When the armature is placed in a first terminal position, it is supported by magnetic forces produced by the constant magnet and the yoke which is used as a bridge in the iron bore.
Claims9
A linear magnetic drive having a first iron core which passes through a first coil to which current can be applied, and has at least one magnetic gap through which a magnetic flux can pass, and having a moveable armature which has a first permanent magnet, wherein in a first limit position of the armature, the first permanent magnet at least partially fills a gap in the first iron core, and a yoke, which is arranged on the armature, rests on one edge of a gap in the first iron core.
