Abstract:
1. A friction clutch for torque transmission from a rotor that can be driven about an axis to an element to be driven, comprising a friction disk clutch with an electromagnet arrangement having a coil former and a ferromagnetically conductive coil support, which supports and at least partially surrounds the coil former, and, adjacent to the coil support, there is a permanent magnet, which is configured to connect an axially movable friction section of the friction disk clutch magnetically to the rotor, and the permanent magnet is arranged on the rotor in such a way that the permanent magnet is covered by essentially no magnetically conductive section of the rotor on a side which is transverse to the direction of magnetization thereof, wherein there is an anchoring web for mounting the permanent magnet on the rotor, comprising a mounting section formed on the rotor, by which the permanent magnet is mounted in a correct position on the rotor.
