Abstract

The invention concerns a system for active reduction of radial vibrations of a rotating shaft (4), especially the drive shaft of an internal combustion engine (1), with at least one active electromagnetic device (7; 10; 15, 16), which is configured and controlled such that it applies radial forces to the shaft (4), which counteract the radial vibrations of the shaft (4).
