Abstract:
A drive system has an electric motor, wherein the electric motor includes a first three-phase stator winding system and a second three-phase stator winding system. The first and the second stator winding system are arranged on the stator in a manner rotated through an electrical phase angle in relation to one another. The drive system includes a frequency converter, wherein the frequency converter has a first bridge circuit arrangement which is designed to generate voltages for the first winding system and a second bridge circuit arrangement which is designed to generate voltages for the second winding system. The first bridge circuit arrangement and the second bridge circuit arrangement are connected in series. A control device is designed to actuate the first bridge circuit arrangement and the second bridge circuit arrangement.

Claim (Index 15):
The drive system as claimed in  claim 9 , wherein\n the first three-phase stator winding system is star-connected, and comprises three phase terminals (u, v, w) and a neutral conductor terminal (n 1 ), wherein the neutral conductor terminal (n 1 ) is electrically connected to the neutral point, the second three-phase stator winding system is star-connected, and comprises three phase terminals (x, y, z) and a neutral conductor terminal (n 2 ), wherein the neutral conductor terminal (n 2 ) is electrically connected to the neutral point, the first bridge circuit arrangement comprises three output terminals ( 3 _ 1 ,  3 _ 2 ,  3 _ 3 ), and the second bridge circuit arrangement comprises three output terminals ( 4 _ 1 ,  4 _ 2 ,  4 _ 3 ), and the frequency converter further comprises:\n a capacitive voltage divider, to which an intermediate circuit voltage (UZ) is applied, wherein a first tap ( 6 _ 1 ) of the capacitive voltage divider is electrically connected to the neutral conductor terminal (n 1 ) of the first three-phase stator winding system, wherein a second tap ( 6 _ 2 ) of the capacitive voltage divider is electrically connected to a connecting node of the first and second bridge circuit arrangements, wherein a third tap ( 6 _ 3 ) of the capacitive voltage divider is electrically connected to the neutral conductor terminal (n 2 ) of the second three-phase stator winding system, wherein the three output terminals ( 3 _ 1 ,  3 _ 2 ,  3 _ 3 ) of the first bridge circuit arrangement are electrically connected to a respective associated phase terminal (u, v, w) of the first three-phase stator winding system, and wherein the three output terminals ( 4 _ 1 ,  4 _ 2 ,  4 _ 3 ) of the second bridge circuit arrangement are electrically connected to a respective associated phase terminal (x, y, z) of the second three-phase stator winding system.
