The invention discloses an electromagnetic friction clutch for driving a fan impeller in the engine compartment of a vehicle. The clutch includes a disk rotor consisting of a plane flat part, a further clutch element which is supported so that it is freely rotatable and which can be driven by the rotor through controllable friction contact, and elements for transmitting a rotational movement according to a principle of an eddy current drive with an eddy current ring fitted to the outer edge area of the disk rotor of the clutch.
