Incorporating Damping in a voice coil actuator can mitigate the effects of vibration in many systems and is typically implemented electromagnetically. The coil is wound on a former of conductive material - a ‘damping ring’ - which behaves as a short circuited turn. As the coil moves, the currents generated in the damping ring produce a force opposing the movement. This force is proportional to the velocity of the moving coil, so resists rapid movements without friction and without impeding slower, controlled motion.
