Scalable, highly dynamic electromagnetic linear drive with limited travel and low transverse forces

A scalable, highly dynamic electromagnetic linear drive having a limited stroke, comprising:

• a stator which has two soft magnet arms;
• an at least partially flat armature made of soft magnet material, which is arranged in a manner allowing movement along a longitudinal axis of movement between the arms of the stator;
• at least two flat stator coils, each with a soft magnet stator coil core and high winding depth, which are attached to the stator, wherein the stator coil cores are part of the soft magnet arms or are connected to the soft magnet arms in a manner allowing magnetic conductance;
• at least one flat armature coil with a soft magnet flat coil core and high winding depth, which is attached to the partially flat armature, wherein the soft magnet flat coil core is part of the partially flat armature and/or formed from the partially flat armature, or the flat armature coil is positioned, with its soft magnet flat coil core, lying in a recess of the partially flat armature;
• a well-defined stroke initiation position and stroke end position;
• at least one switchable means which is designed to hold the armature in at least one end position against a return force;
• a switchable power supply comprising an energy storage device and at least one switch;
• and
• wherein the at least one flat armature coil has a coil axis which is oriented normal to the longitudinal axis and parallel to the coil axis of the stator coils, and wherein it is possible to feed current to the at least one flat armature coil in the opposite direction as the stator coils in order to move the armature from the stroke initiation position into the stroke end position.
