Abstract: An electric linear repetitive pulsed drive for an operation of apparatuses, in particular for an operation of apparatuses for improving an efficiency of which a working energy that is output in a pulsed manner, with at the same time low repetition frequencies, is advantageous, includes a magnetic circuit with an air gap and an electric coil, a magnetic shape-memory adjustment element and a reset unit, and a control electronics unit, wherein the electric linear repetitive pulsed drive outputs its energy in discrete-time fashion, bundled in short time intervals, that is in pulses.
