US Patent 10550910 Magnetic damper for vibration absorbers

Rotationally symmetric dampers (FIG. 3A) of a new type for eliminating and avoiding vibrations in machines and installations, particularly wind turbines. The damping occurs by magnetically generated eddy currents. In addition, vibration absorbers, particularly pendulum absorbers (7), are equipped with such magnetic dampers, and to installations, particularly wind turbines, that are exposed to vibratory forces and that comprise such vibration absorbers.
