Electromagnetic actuator having a magnetostrictive element and method for operating the electromagnetic actuator

摘要

An electromagnetic actuator (1) with an armature (3) mounted so that the armature can be moved by virtue of a bearing arrangement (6A, 6B) and an electric coil (4) is provided for moving the armature (3). A magnetostrictive element (8) is provided, by which relative movement between the armature (3) and at least part of the bearing arrangement (6A, 6B) is produced.
