Abstract

A method for operating an electric motor that drives a displacement pump stage to deliver a liquid through a hydraulic system to supply the liquid to at least one consumer. A periodically repeating pressure fluctuation of the liquid that occurs during delivery operation is at least partially compensated by virtue of the rotational speed of the electric motor being manipulated in accordance with the periodically repeating pressure fluctuation.
