Abstract
A tool for working a substrate, having a stator and a working piston, which is intended to move relative to the stator along a working axis, and having a drive, which is intended to drive the working piston along the working axis from a starting position onto the substrate, the drive having a stator coil arranged on the stator and being intended to apply electrical current of a first current intensity I1 to the stator coil in order to generate a magnetic field which accelerates the working piston relative to the stator, the drive having a piston coil arranged on the working piston and being intended to apply electrical current of a second current intensity I2 to the piston coil in order to generate a magnetic field which accelerates the working piston relative to the stator, the second current intensity I2 being less than the first current intensity I1.
