Abstract:
An induction machine includes a stator and a rotor, wherein a stator winding is arranged within the stator, a control device controls a converter such that the converter connects the stator winding to a power-supply network such that a stator current flows within the stator winding, and the stator current has a field-forming current component and a torque-forming current component, where the control device controls the converter such that, during load periods, a torque acts between the stator and the rotor, controls the converter during periods of rest such that a torque acts between the stator and the rotor, controls the converter at least at the beginning of the periods of rest such that the field-forming current component has a nominal value, and controls the converter during the load periods such that the field-forming current component has a lower value than the nominal value.
