Abstract
The invention relates to a method for detecting wear in a frictionally locking clutch () or a frictionally locking brake (), the clutch () or the brake () having at least one electrically excitable coil () and at least one element () which can move in rotation about an axis (), to bring about frictional locking with at least one corresponding mating element (), at least the element () which can move in rotation or the corresponding mating element () being axially movable, and it being possible to form an airgap (). The wear () can be inferred by virtue of the fact that the electric current is measured by the electrically excitable coil (), evaluated and the evaluation compared with at least one reference value.
