Abstract
An electromagnetic positioning device (), having a stationary spool unit (), having a moveably guided anchor (), which forms a positioning section () and which can be axially displaced along a displacement axis (V) in response to supplying the spool unit () with current, as well as having a one-part cup-shaped yoke-core element (), which receives the anchor () and which includes a core section () as well as a yoke section () and which has a yoke-core bottom () extending perpendicular to the displacement axis (V) and a yoke-core sheath extending perpendicular to the yoke-core bottom () along the displacement axis (V), a longitudinally cut transition area () reduced in thickness and arranged between the core section () and the yoke section () being realized in the yoke-core sheath. It is intended that a guide pin () for the anchor () is fixed, preferably pressed in, in a, preferably centric, guide pin recess () in the yoke-core bottom () and protrudes axially into a, preferably centric, guide opening () of the anchor () and can be displaced relative to the anchor () during its displacement movement.
