Abstract
An active vibration canceler, including a canceler mass that is attached by a spring device to a supported bearing. The canceler mass is movable by a plunger coil arrangement and a permanent magnet so as to result in at least partial suppression of relative movements of the supported bearing in at least one frequency range. The spring device joins the canceler mass and the supported bearing for relative movement in one direction. The spring device includes at least three leaf springs arranged in at least two planes, which leaf springs, in the idle position, extend circumferentially in the same direction.
