Linear actuator, preferably for an active hydraulic engine mount

摘要

The present invention relates to a linear actuator (1), preferably for an active hydraulic engine mount, with a stator (11) and with an armature (12) movable relative to the stator (11), wherein the stator (11) and / or the armature (11) 12) has at least one coil (14), wherein the stator (11) and / or the armature (12) at least one magnet (13), preferably at least one permanent magnet (13), and wherein between the stator (11) and the armature (12) at least partially an air gap (15) is formed. The linear actuator (1) is characterized in that the armature (12) is connected to the stator (11) by means of at least one elastomer body (18) in such a way that the armature (12) is separated from the elastomer body (18) with respect to the stator (11). movably guided and can be reset by the elastomeric body (18).
