    Abstract: The invention relates to a method for correcting a measured value of an angle of rotation (153) of the rotor of an electric machine, in particular of the rotor of a synchronous machine (155), wherein the method comprises the following steps: measuring a value of a sensor signal, wherein the value of the sensor signal is indicative of an angle of rotation (153) of the rotor; calculating the angle of rotation (153) of the rotor on the basis of the measured value of the sensor signal; determining a correction value (105) in accordance with the calculated angle of rotation of the rotor and from a correction table (106) determined in advance on the basis of the angle of rotation of the rotor; correcting (111) the measured value of the sensor signal (101) by the determined correction value (105); determining the correction value (105) by comparing an actual angle-of-rotation curve with an ideal angle-of-rotation curve; and storing (109) the difference between the actual angle of rotation and the ideal angle of rotation as a correction value (105) in the correction table (106).
