Abstract
A balancing device for each rotating piece, the rotating piece defining an axis of rotation, the balancing device including: a fixed portion, a mobile portion defining a central axis. The balancing device constrained to the rotating piece so that the central axis substantially coincides with the rotation axis. The balancing device including at least one eccentric mass, rotatable around the central axis and not balanced with respect to the central axis. The balancing device further including apparatus for movement of the eccentric masses, including a magnetic brake and being able to rotate the eccentric masses, with respect to the rotating piece around the central axis.
