Abstract:
Methods and an apparatuses for determining the movement of a synchronous machine are provided. An apparatus for determining the movement of a synchronous machine includes a determination for at least one electrical magnitude of the synchronous machine; a determination of the position error of the rotor of the synchronous machine, which is fitted to determine the position error of the rotor on the basis of the aforementioned at least one electrical magnitude of the synchronous machine; and also a correction of the movement signal of the incremental sensor, which is fitted to correct the read movement signal of the incremental sensor on the basis of the aforementioned determination of the position error of the rotor of the synchronous machine.
