Electrodynamic drive
The invention relates to a handheld nail setting device comprising highly dynamic electromagnetic drive in the manner of a Thomson coil with soft-magnetic frame, comprising a first excitation coil (30) whose winding height is greater than its length, which hence is flat; a soft-magnetic frame in which the first excitation coil is arranged and against which it abuts, and which in in the manner of a pot magnet constitutes an open magnetic circuit which includes an outer region, a bottom and an inner region, and which is open on its end face, wherein the first excitation coil at least partly encloses the inner part of the frame; a short circuit armature preferably formed hollow cylindrical at least on its side facing the first excitation coil, which is movably mounted along an axis and which in its stroke starting position dips into the end-face opening of the frame and thereby at least partly encloses the inner part of the frame, wherein the frame entirely or predominantly is formed of a soft-magnetic composite material or one or more sheet stacks, which has a saturation flux density of at least 1.5 T and an effective specific electrical conductivity of not more than 10.sup.6 S/m, and the first excitation coil and/or the frame include at least one means for strain relief, in particular in the form of an enclosure in order to at least partly absorb at least the radial forces occurring on the first excitation coil during an actuating operation vertically to the direction of movement, and wherein the Lorentz force acting on the short circuit armature is used to perform work.
