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 16):
The drive system as claimed in  claim 9 , wherein the frequency converter further has:\n a third bridge circuit arrangement, which is configured to generate potentials for the first winding system, and a fourth bridge circuit arrangement, which is configured to generate potentials for the second winding system, wherein the third bridge circuit arrangement and the fourth bridge circuit arrangement are connected in series, wherein the first three-phase stator winding system comprises six phase terminals (u, v, w, u\u2032, v\u2032, w\u2032), wherein the second three-phase stator winding system comprises six phase terminals (x, y, z, x\u2032, y\u2032, z\u2032), wherein the first bridge circuit arrangement comprises three output terminals ( 3 a _ 1 ,  3 a _ 2 ,  3 a _ 3 ), the second bridge circuit arrangement comprises three output terminals ( 4 a _ 1 ,  4 a _ 2 ,  4 a _ 3 ), the third bridge circuit arrangement comprises three output terminals ( 3 b _ 1 ,  3 b _ 2 ,  3 b _ 3 ), and the fourth bridge circuit arrangement comprises three output terminals ( 4 b _ 1 ,  4 b _ 2 ,  4 b _ 3 ); and wherein the frequency converter further comprises:\n a capacitive voltage divider, to which an intermediate circuit voltage (UZ) is applied, wherein one tap ( 6 \u2032_ 1 ) of the capacitive voltage divider is electrically connected to a connecting node of the first bridge circuit arrangement, the second bridge circuit arrangement, the third bridge circuit arrangement and the fourth bridge circuit arrangement, wherein the output terminals ( 3 a _ 1 ,  3 a _ 2 ,  3 a _ 3 ) of the first bridge circuit arrangement and the output terminals of the third bridge circuit arrangement are electrically connected to a respective associated phase terminal (u, v, w, u\u2032, v\u2032, w\u2032) of the first three-phase stator winding system, and wherein the output terminals ( 4 a _ 1 ,  4 a _ 2 ,  4 a _ 3 ) of the second bridge circuit arrangement and the output terminals ( 4 b _ 1 ,  4 b _ 2 ,  4 b _ 3 ) of the fourth bridge circuit arrangement are electrically connected to a respective associated phase terminal (x, y, z, x\u2032, y\u2032, z\u2032) of the second three-phase stator winding system.
