A method for determining the phase currents (I k,l,m) of an electric machine with a converter and a stator comprising stator windings with a phase number of at least three, in which the phase currents (I l,m) of a number of measurement phases, which is at least two, are measured, wherein the phase currents of the measurement phases are each measured in a measurement interval (M l,m) when the active switching elements in a lowside path of the converter associated with the measurement phases are driven in a switching interval (S l,m), which is limited by a switch-on time (E l,m) and a switch-off time (A l,m), wherein the phase currents (I k) of the remaining phases are determined computationally from the measured phase currents (I l,m) in such a way that at least the measured phase currents (I l,m), a spatial angle of the measurement phases and a spatial angle of the remaining phases are used for the computational determination, the measurement interval (M l,m) being selected in such a way that the switch-on times and switch-off times (A k,l,m) of the active switching elements of the converter assigned to the phases of the stator lie outside the measurement interval, characterized in that the switch-on times (E k,l,m) and the switch-off times (A k,l,m) are detected and sorted in time sequence, the time difference between a switch-on time (E k,l,m) or a switch-off time (A k,l,m) and the directly adjacent switch-on time (E k,l,m) or switch-off time (A k,l,m) is detected and compared with the measurement interval (M l,m), in particular with the time duration of the measurement interval (M l,m), the measurement interval (M l,m) being selected and arranged in time between the respective switch-on times (E k,l,m) or switch-off times (A k,l,m) in such a way that the greatest possible number of phase currents can be measured within the measurement interval (M l,m). in which the phase currents (I l,m) of a number of measurement phases, which is at least two, are measured, wherein the phase currents of the measurement phases are each measured in a measurement interval (M l,m) when the active switching elements in a lowside path of the converter associated with the measurement phases are driven in a switching interval (S l,m), which is limited by a switch-on time (E l,m) and a switch-off time (A l,m), wherein the phase currents (I k) of the remaining phases are determined computationally from the measured phase currents (I l,m) in such a way that at least the measured phase currents (I l,m), a spatial angle of the measurement phases and a spatial angle of the remaining phases are used for the computational determination, the measurement interval (M l,m) being selected in such a way that the switch-on times and switch-off times (A k,l,m) of the active switching elements of the converter assigned to the phases of the stator lie outside the measurement interval, characterized in that the switch-on times (E k,l,m) and the switch-off times (A k,l,m) are detected and sorted in time sequence, the time difference between a switch-on time (E k,l,m) or a switch-off time (A k,l,m) and the directly adjacent switch-on time (E k,l,m) or switch-off time (A k,l,m) is detected and compared with the measurement interval (M l,m), in particular with the time duration of the measurement interval (M l,m), the measurement interval (M l,m) being selected and arranged in time between the respective switch-on times (E k,l,m) or switch-off times (A k,l,m) in such a way that the greatest possible number of phase currents can be measured within the measurement interval (M l,m).
