Abstract: The invention relates to an earthing device for preventing rotor-induced bearing currents in an electric motor, comprising an electrically conductive annular element having retaining means arranged thereon, to which means fiber bundles are fastened, via which bundles electrical discharge of a static charge to at least one discharge element can be carried out, wherein the fiber bundles are fastened so as to be oriented in an oblique angular position with respect to a radial plane which is perpendicular to an axial center line of the annular element and/or with respect to an axial plane and have a length protruding from the retaining means of the annular element which is greater than that required to bridge a radial spacing between the annular element and the discharge element.
