The subject matter of the present invention relates to an electric machine (10) for converting mechanical energy into electrical energy or vice-versa, in particular a generator such as a Lundell alternator and/or a belt-driven starter generator, having at least two conductive components with a magnetic flux therebetween during conversion, in particular having at least one rotor (20) and at least one stator (16) associated therewith, wherein a damping device (100) of the type of a shim (101) is integrally bonded without strain to at least one of the two components, that is to say without strain relative to another component, or between adjacent components, in order to reduce magnetic noise. The invention further relates to a method and to a use thereof.
