Abstract
The invention relates to a method for determining a rotor position of a rotatory, multi-phase, electronically commutated electric machine (). Said electric machine () comprises several phase windings () which can be supplied with current by means of phase connectors. Said method consists of the following steps: phase currents and phase connections are identified on phase connections of the electric machine (); the induced currents on the phase connections of the electric machine () are determined from the identified phase currents and phase flows; the identified current indicator of the induced current is provided with respect to a Cartesian coordination system which is fixed to a stator by the induced currents; the position of the rotor is identified as a space indicator angle of the current indicator of the induced current provided with respect to the Cartesian coordination system which is fixed to the stator.
