Abstract: A magnetic holding brake (1) having at least one turning brake member (4) allocatable to a rotatable part (2) of an actuator (3) and a fixed brake member (6) allocatable to a torque-proof part (5) of the actuator (3). The turning brake member (4) and the fixed brake member (6) each at least have one permanent magnet (7, 8) of different polarity. The permanent magnets are lying opposite to each other in a pre-defined relative position of the turning brake member (4) and the fixed brake member (6) under exertion of a braking or holding torque. In this manner, the possibility exists that a holding in the so-called “fail as is”-mode is more easily and reliably and at the same time cost-efficiently achievable without wear or further energy demand.
