Abstract
A drive system has: a three-phase motor, having: a shaft, a first three-phase winding set, having: a three-phase stator winding for connection to a three-phase alternating voltage network and a three-phase rotor winding, which is coupled to the shaft in a mechanical, rotationally fixed manner, a second three-phase winding set, having: a three-phase stator winding for connection to the three-phase alternating voltage network in such a manner that rotary field is produced that runs in the opposite direction to a rotary field that is produced by the stator winding of the first winding set.
