Abstract (en)

[origin: US6496092B1] An electromagnetic drive device is proposed comprising an electromagnet (21) having a magnetizable core (22) with a plurality of limbs (23 and 24) and an energizable winding arrangement (35) surrounding at least one limb (23 and 24) of the core (22). Furthermore there is a magnetizable magnet armature (15) able to be moved in relation to the core ((22) by varying the winding arrangement current. The (22) core has at least one U arrangement and is formed essentially by a plurality of sheet metal elements (30) resting against each other and extending athwart the direction of the parallel limbs (23 and 24), the parallel limbs being respectively surrounded by one winding (33 and 34) of the winding arrangement (35).
