Abstract

The invention relates to a method for operating a synchronous machine (1) by means of a three phase power controller (4) which comprises three semiconductor controllers (6 7 8) and is connected to a three phase network comprising the following steps: determining the phase difference between the magnet wheel voltage of the synchronous machine (1) and the network voltage of the three phase network; determining the rotational speed of the rotor of the synchronous machine; determining the phase position of the three phase network; determining at least some of the stator currents of the synchronous machine (1); determining a decision characteristic number on the basis of an advance calculation of the torque curve in the event of activation of at least two of the semiconductor controllers (6 7 8) while taking into account the current values for phase difference rotational speed stator current and phase position; and determining at least one switching time point on the basis of the decision characteristic number wherein the at least two semiconductor controllers (6 7 8) are activated at the switching time point.
