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).

Abstract: In a method for uniform application of treatment agents to a textile rope in a dyeing machine, the endless rope is made to revolve in a closed tank by means of a Venturi feed nozzle subjected to a gaseous feeder medium, and is thus exposed to the action of a liquid treatment agent. The treatment agent is stored, without contact with the rope, in a chamber that is separate from the rope and is made to act on the rope, without mixing with treatment agent draining from the rope, with a quantity of treatment agent per unit of time that is controlled as a function of time.
