Abstract
The invention relates to a method for identifying the position of a rotor of an electric motor, in which method a target arranged on a rotor is sensed using a sensor. In a method which can be carried out cost-effectively and nevertheless delivers highly accurate sensor signals, a rotational movement of the rotor is detected using an inductive or a capacitive sensor.
