Abstract
In a method for ascertaining the phase currents of an electric machine having a power converter and a stator with a phase number of four or more, the phase currents of a measuring number of measuring phases is measured, which is at least two and is lower by at least two than the phase number, and the phase currents of the remaining phases are arithmetically determined from the measured phase currents, at least the measured phase currents, a spatial angle of the measuring phases and a spatial angle of the remaining phases being used for the arithmetical determination.
