Abstract

An inductive rotor position sensor device for detecting a rotor angular position of a rotor of an electric machine. The inductive rotor position sensor device includes a transmitter coil for generating electromagnetic waves and a receiver coil for detecting the electromagnetic waves generated by the transmitter coil and influenced by the rotor, and includes a processing unit, which is designed to activate the transmitter coil and to evaluate the electromagnetic waves detected by the receiver coil for determining the rotor angular position. The coils and the processing unit are situated on a shared circuit board. The coils are situated on a front side, and the processing unit is situated on a rear side of the circuit board which faces away from the front side.
