Abstract
To minimize the energy required for operation of a rail vehicle, in a drive system that has an intermediate circuit converter 1 and a three-phase motor 7 fed by it, the intermediate circuit voltage in the intermediate circuit 12 and/or the magnetic flux in the drive motor 7 are optimized to correspond to the actual operating requirements, including, if necessary, the energy expenditure for the auxiliaries 9 that are provided to cool the components.
