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.
Claims14
A target for determining a position of a rotor, comprising a geometric shape that is unambiguous over a rotation of the rotor and is scannable using a sensor, and
- an electrically conductive material defines the unambiguous geometric shape and is arranged on a substrate.
