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.
