A drive system (100) has: a three-phase motor, having: a shaft, a first three-phase winding set (1), having: a three-phase stator winding (1a) for connection to a three-phase alternating voltage network (U, V, W) and a three-phase rotor winding (1b), which is coupled to the shaft in a mechanical, rotationally fixed manner, a second three-phase winding set (2), having: a three-phase stator winding (2a) for connection to the three-phase alternating voltage network (U, V, W) in such a manner that a rotary field is produced that runs in the opposite direction to a rotary field that is produced by means of the stator winding (1a) of the first winding set (1), and a three-phase rotor winding (2b), which is coupled to the shaft in a mechanical, rotationally fixed manner, a first inverter (3), which is coupled to the shaft in a mechanical, rotationally fixed manner and which is coupled electrically to the three-phase rotor winding (1b) of the first winding set (1), and a second inverter (4), which is coupled to the shaft in a mechanical, rotationally fixed manner and which is coupled electrically to the three-phase rotor winding (2b) of the second winding set (2), wherein the first inverter (3) and the second inverter (4) are electrically coupled in such a manner that electrical power can be transmitted between the inverters. |
