To provide a method for determining an angular position of a rotor of a rotating electric machine.
A set of stator windings is short-circuited by a converter unit for at least three presettable times (T0, T1, T2) of short circuits within the rotation of a rotor at an assumed speed of a prescribed rotor. Next, phase angles (T0, T1 and T2) of respective stator currents (iST0, iST1 and iST2) are determined for each of times (T0, T1 and T2)of short circuits, and phase angle differences (i1, i2) are formed from phase angles (T0, T1 and T2) determined in respective times of two adjacent short circuits on a time basis. Next, a minimum phase angle difference (imin) is determined from these phase angle differences (i1, i2), and in the case of a negative minimum phase angle difference (imin), the correction (ic) of a phase angle is added to the phase difference (T2) determined in the most recent time.
