Abstract

To prevent damage to an electric machine (1), for example in a motor vehicle, due to axial loading of the rotor bearing in a simple manner, a cushioning element (11, 18, 22, 27) is proposed to absorb axial loading of the bearing system (6, 7), thereby also reducing the axial play (8) of the bearing system (6, 7). When the bearing system (6, 7) is axially loaded, the cushioning element (11, 18, 22, 27) serves to convert kinetic energy into deformation energy.
