Abstract
An actuator (A) for a component ( ), comprising at least one defined stop position, in particular to a brake component actuator of a yarn brake (B), for a selective braking of a running yarn (Y) which actuator has a drive element (D) for linear or rotational adjustment of the component ( ). Said actuator is provided with at least one stop device (C). The stop device (C) consists of an additional body (Z), supported in a displaceable manner on a motion damping device (F, G, H). The actuator (A) in the yarn brake is a reversible motor, suitably a magneto-electric motor (M) for rotational movement. An additional body (Z), supported in a displaceable manner on a motion damping device, is provided in each stop device, at which the yarn brake is to stop. During a linear adjustment of the component ( ), the mass (m ) of the additional body (Z) matches the mass (m) of the displaced parts. In contrast, with a component ( ) that can be rotatably adjusted, the moment of inertia(I ) of the additional body (Z) matches the moment of inertia (I) of the displaced parts, in relation to the axis of rotation.
