A method for determining the phase currents (I k,l,m ) of an electric machine with a converter and a stator comprising stator windings (11-15) 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 ). <EOS>
