Abstract

The invention relates to a method (400) for regulating an electric machine (190), comprising a harmonic filter (150), said harmonic filter (150) comprising a second filter (142) and a filter output transformer (132). The method has the steps of: ascertaining (410) a feedback variable (Idq); determining (414) a filter specification variable (FV); filtering (415) the filter specification variable (FV); ascertaining (417) a filtered feedback variable without harmonic components (IdqFunda); and energizing (480) at least one winding of the electric machine (190) on the basis of the filtered feedback variable without harmonic components (IdqFunda).
