Abstract: The invention relates to an electromagnetic positioning device (10) having energizable stationary coil means (1), a magnetic guide element (2) associated thereto and having a core section (2a) and an anchor unit (3) moveable in relation to the guide element (2) and along an axial movement direction (L) as a reaction to an energization of the coil means (1), wherein the guide element (2) is a hollow cylinder that partially surrounds the anchor unit (3). The positioning device (10) has an ultra-wide-band sensor unit (4) which is preferably integrated in the guide element (3) and is designed for measuring the position and/or the displacement of the anchor unit (3) in the guide element (2).

Abstract: An electromagnetic positioning device includes an armature member for actuating a positioning partner and movable in an armature space relative to a stationary core (30). The armature member conducts magnetic flux upon energization of a stationary coil (32). The coil has a coil support with a winding and at least one external contactable connector (46) embedded at least in sections in the core and/or surrounded by the core. The core has an end surface (34), which is planar at least in sections, for interacting with the armature member. The core and the coil are embedded in and/or surrounded by a one-piece pot-like and/or cup-like housing (38) made of a material suitable for deep-drawing in such a manner that the core rests on a membrane-like, continuous and closed base section of the housing, the base section realizing a boundary surface of the armature space.
