A sensor device for an electric machine includes a rotor shaft mounted rotatably in a housing, with a signal generator that is or can be joined non-rotatably to the rotor shaft and is or can be arranged axially on the end face of the rotor shaft. A signal sensor is fixed to the housing opposite on the end face of the signal generator and at a distance from the signal generator. The signal sensor acquires an axial distance from the signal generator.
