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 rotating in opposition results with respect to a first stator rotating field which is generated by means of the first stator winding, and a rotor winding system which is mechanically coupled in a rotationally fixed manner to the shaft. The drive system further includes at least one inverter which is mechanically coupled in a rotationally fixed manner to the shaft and which is electrically coupled to the rotor winding system, wherein the at least one inverter is configured to generate actuation signals for the rotor winding system such that a first rotor rotating field and a second rotor rotating field rotating in opposition to the first rotor rotating field are generated. The at least one inverter is configured to generate the actuation signals for the rotor winding system solely depending on signals detected on the rotor side.
