Abstract: The invention relates to a generator system for a motor vehicle, which comprises an asynchronous generator and a converter. The converter serves for the production of converter output voltages from a direct current source, which form a three-phase system which, inside the machine, produce a rotating field suitable for the generator function for the formation of rotating fields suitable for the generator function. The converter output voltages thereby have a frequency—referred to in the following as a CO frequency—which is changeable in dependence on the range of rotational speed of the generator. The voltage curve of the converter output voltages can be broken down into a primary component with a sinusoidal voltage curve of the CO frequency and into at least one additional secondary component with a sinusoidal voltage curve with an odd-numbered multiple of the CO frequency.
