摘要： A setting tool for driving fastening elements into a substrate, comprising a holder for holding a fastening element; a drive-in element for transferring a fastening element held in the holder into the substrate along a setting axis; and a drive for driving the drive-in element toward the fastening element along the setting axis, wherein the drive comprises an electrical capacitor; a squirrel-cage rotor arranged on the drive-in element; and an excitation coil; which during discharge of the capacitor is flowed through by current and generates a magnetic field that accelerates the drive-in element toward the fastening element, wherein the setting tool further comprises a soft-magnetic frame, in which the excitation coil is embedded; and a supporting structure; wherein, at least during the discharge of the capacitor, the supporting structure exerts on the soft-magnetic frame a pretensioning force directed radially inward with respect to the setting axis.
