Abstract: The present invention relates to an electric drive system for or in a motor vehicle, having: at least one synchronous machine, which has a double rotor and a distributed winding placed in a stator core, wherein the double rotor is constructed from flux-carrying material made of solid material, wherein the winding is designed to be self-supporting for torque support; and at least one three-stage or multi-stage inverter circuit that is coupled to the synchronous machine at a load output and that is designed to convert a DC voltage received on the supply side into an AC voltage via which the synchronous machine can be driven via the load output, wherein the inverter circuit has a controllable three-stage or multi-stage inverter.
