摘要
A method determines a correction value for a control device for an electric machine, which describes an angular difference between a position of a d-axis of the electric machine and an actual position of the d-axis. The correction value is determined in a rotating state of a rotor of the electric machine as a function of a d voltage value describing a d component of a stator voltage specified by the control device in the initial configuration, of a q voltage value describing a q component of the stator voltage specified by the control device in the initial configuration, of a flux value describing a magnetic flux of the rotor, a speed value describing the speed of the rotor in the rotating state, and of a calibration value describing a speed-dependent voltage error of the d component of the stator voltage.
