A linear actuator for an active motor mount of a motor vehicle includes a stator which has an electrically energizable coil for generating an electromagnetic field, as well as a magnetic armature which is mounted axially movable with regard to a longitudinal axis of the coil and has at least one permanent magnet ring which opposes the stator and has several permanent magnet ring segments. Between a surface of the permanent magnet ring segments which faces the stator and a surface of the stator which faces the permanent magnet ring segments there exists an angular gap with a gap angle (α) of preferably 4°.
