Abstract: The present invention relates to a stator for a radial flux double-rotor machine, in particular for a wheel hub motor. The stator includes a stator core; a winding which is placed in the stator core and is designed to be self-supporting for torque support of the stator, wherein the winding protrudes beyond the stator core at least one axial end; and a support device which is arranged axially offset with respect to the stator core and is designed for form-fitting engagement with the winding at the at least one axial end for torque support.

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.
