The invention relates to a method for operating a synchronous machine by means of a three-phase AC power controller, which is connected to a three-phase network, comprising the following steps: determining the phase difference between the magnet-wheel voltage of the synchronous machine 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 a decision characteristic number on the basis of a stored data table that has been calculated in advance, which data table associates a decision characteristic number with value triples of phase difference, phase position, and rotational speed; and determining at least one switching time point on the basis of the decision characteristic number. |
