Abstract:
A drive system includes a three-phase motor having a shaft, a first three-phase stator winding, which is to be connected to a three-phase AC voltage grid, a second three-phase stator winding, which is to be connected to the three-phase AC voltage grid in such a way that a second stator rotating field is produced rotating in opposition with respect to a first stator rotating field, which is generated by the first stator winding, and a rotor winding system which is mechanically coupled in rotationally fixed fashion to the shaft. The drive system further includes at least one inverter, which is mechanically coupled in rotationally fixed fashion to the shaft and which is electrically coupled to the rotor winding system, wherein the at least one inverter is designed to generate actuation signals for the rotor winding system in such a way that a first rotor rotating field and a second rotor rotating field are generated, wherein the first rotor rotating field interacts with the first stator rotating field in such a way that a first motor speed and a first torque are produced, and wherein the second rotor rotating field interacts with the second stator rotating field in such a way that the first motor speed and a second torque are produced, wherein the second torque has an identical direction of action with respect to the first torque.
