Abstract: The present invention relates to an electric motor, the electric motor including: a stator, which is composed of layered metal sheets, a motor support made of an electrically conductive material, a cable connection comprising an earth line cable, and at least one connecting and contacting element made of an electrically conductive material, wherein the connecting and contacting element is configured and arranged on the electric motor such that it provides an earth connection between the stator and the motor support or between the stator and the earth line cable of the cable connection, and wherein the stator and the motor support are fastened to one another independently of the connecting and contacting element.

Abstract: The invention relates to a rotor hub assembly for an electric fan, in particular for a radiator fan of a motor vehicle, comprising a hub cup, which rotates during operation and which has air outlet guides on the inside of the hub cup, which air outlet guides are arranged and shaped in such a way that the air outlet guides guide and accelerate cooling air, wherein a magnetic return cup is arranged inside the hub cup, which return cup has air passage openings, which, together with the air outlet guides, form continuous air outlets for a cooling air flow from the pressure side to the vacuum side of the fan. The invention further relates to an electric fan having such a rotor assembly.
