Abstract

See full text

An actuator has an electrically conductive coil which has a longitudinal axis and windings through which a current can flow. The coil is surrounded by a highly permeable first ferromagnetic body so that the first body has projections of highly permeable ferromagnetic material above and below the coil in the longitudinal direction. The actuator has a magnet spaced apart from the coil so that a gap forms therebetween. The magnet is surrounded by a highly permeable second ferromagnetic body so that the second body has projections of highly permeable ferromagnetic material above and below the magnet in the longitudinal direction. The magnet is statically mounted with the second body and the coil is spring mounted with the first body so that the coil and first body oscillate in the longitudinal direction when an alternating current flows through the coil. The coil is outside the magnet perpendicular to the longitudinal axis.
