Abstract:
A method for energizing the stator windings of a rotating field machine operable in motor mode, the stator windings respectively being impinged upon with phase currents that are predefined using a vector-based method. The phase currents are impinged upon at least in part with bias currents that are determined by the vector-based method in such a way that they exhibit no torque effectiveness in the rotating field machine.
