Abstract

The invention concerns a starter/generator for an internal combustion engine (1), especially that of a motor vehicle, with an electric rotary-field machine (4), which exercises the starter and generator function; and at least one invertor (17) for generating the voltages and/or currents of variable frequency, amplitude and/or phase required for the magnetic fields of the electric machine (4); wherein the electric machine (4) starts the internal combustion engine (1) by merging in from standstill.
