<p>The drive has a motor (1), and a spring (14) supported on a front side of a rotor (2) and imposing force on a brake disk (9) so that a friction lining (10) is clampingly retained between the disk and a bearing shield (15). The disk has a metal part (12), which attracts the disk towards the rotor by magnetic filed so that the friction lining between the disk and the bearing shield is released. An electro conductive insert ring (16) is inserted into a ring like nut (13'), which is formed between a shaft (4) and a short circuit ring (6').</p> |
