摘要:
The invention relates to a method for providing information on a rotor position of a rotor of an electric machine (2) for utilization in a function connected downstream, comprising the following steps: —determining at least one electric operating variable of a stator winding of the electric machine, particularly a phase current and/or a phase voltage; —determining a rotor position as a function of the electric operating variable—providing information on the rotor position determined as a function of the electric operating variable for the function connected downstream if the rotational speed of the electric machine (2) exceeds a threshold rotational speed (SW).
