    Abstract: The invention relates to a drive system (100) having: a three-phase motor having: a shaft, a first three-phase stator winding (1 a) which can be connected to a three-phase AC voltage network (U, V, W), a second three-phase stator winding (1b) which can be connected to the three-phase AC voltage network (U, V, W) to generate a second stator rotating field rotating in the opposite direction to that of a first stator rotating field produced by means of the first stator winding (1a), a rotor winding system (2) mechanically coupled to the shaft for conjoint rotation, and at least one inverter (3, 4), which is mechanically coupled to the shaft for conjoint rotation and is electrically coupled to the rotor winding system (2). The at least one inverter (3, 4) is designed to generate drive signals for the rotor winding system (2) in such a manner that a first rotor rotating field and a second rotor rotating field are produced. The first rotor rotating field interacts with the first stator rotating field in such a manner that a first motor rotational speed and a first torque result, and the second rotor rotating field interacts with the second stator rotating field in such a manner that the first motor rotational speed and a second torque result, the second torque having an identical direction of action in relation to the first torque.
