The position of a moveable component which is coupled to an electric machine is ascertained, where the electric machine serves, in the event of manual movement of the component, as a generator for generating electric energy for a position ascertainment arrangement. The coupling of the electric machine with the component is configured such that a magnetic attraction reaction and/or repelling reaction between magnetic and/or magnetized parts of a rotor and of a stator of the electric machine results in a short-term acceleration of the rotor, which is unhindered by the coupling, and in a resulting short-term increase of the electric energy generated.
An apparatus (1) for ascertaining the position of a moveable component (3) coupled to an electrical machine (2), wherein with a manual movement of the component (3) the electrical machine (2) is used as a generator for generating electrical energy for a position ascertainment arrangement and wherein the coupling (8) of the electrical machine (2) with the component (3) is embodied such that a magnetic attraction reaction and/or repelling reaction between magnetic and/or magnetized parts of a rotor (10) and a stator (11) of the electrical machine (2) result in a short-term acceleration of the rotor (10) which is unhindered by the coupling (8) and a short-term increase in the generated electrical energy resulting therefrom.
