Abstract
A method for determining an offset of an angular position encoder is associated with a rotor of an electric machine, wherein a reference offset of a reference angular position encoder of a reference electric machine is known at a reference rotational speed and a reference current with a reference phase angle and a reference absolute value. The method includes the steps of applying a current having the reference absolute value; setting a phase angle of the current to achieve the reference rotational speed; comparing the phase angle with the reference phase angle and the reference offset; and determining the offset on the basis of this comparison.
