Abstract (en)
[origin: DE102004034296B3] The device has an electromagnet (1) with a core (1.2) and a stimulation coil (1.1), an armature (2) and spring element (5) and a yoke (1.3) extending in the armature's direction of motion and connected to the core. The armature has a polarized permanent magnet (2.2) enclosed by upper and lower armature plates (2.3,2.1) in a sandwich construction that contacts the yoke at least with one end of the upper plate and there is a secondary air gap (3) between one end of the lower plate and the yoke.
