Abstract (en)
[origin: WO2022117615A2] The invention relates to a method for determining correction information for an electric machine (7) which has a stator winding and a rotatably mounted rotor having a plurality of pole pairs, wherein: a reference rotational angle (φRef) of the rotor is selected; an actual variable influenced by a rotation of the rotor is determined and is monitored for interference waves (SW); when an interference wave (SW) is detected, an interference-wave correction instruction which is based on the reference rotational angle (φRef) and is intended for compensating for the detected interference wave (SW), and a reference feature of the interference wave (SW) based on the reference rotational angle (φRef) are determined; a reference rotational angle value of the reference rotational angle (φRef) is determined on the basis of a rotational angle interval (Δφel) covered during an electrical revolution of the rotor; and the determined interference-wave correction instruction, the determined reference feature and the determined reference rotational angle value are assigned to one another and stored as correction information.
