Abstract
An electromagnet for producing a linear movement includes a housing, an exciter coil arranged in the housing, a pole core and an armature assembly, which is mounted centrally in the exciter coil and has a displaceable main armature and a displaceable armature disc. In the de-energized state of the exciter coil, an air gap is formed between the main armature and the armature disc and, The armature assembly has an elastic element, the preload force of which can produce an elastic force fit between the main armature and the armature disc in the energized state of the exciter coil in such a way that the armature disc is moveable towards the pole core, thereby producing the air gap, as soon as the magnetic force falls below the preload force. The electromagnet as an actuator thus acts alone with a defined spring preload and spring rate of the elastic element.
