DRIVE SYSTEM, ELECTRICAL MACHINE SUITABLE FOR USE IN SUCH A DRIVE SYSTEM AND METHOD OF OPERATING AN ELECTRICAL MACHINE IN THE DRIVE SYSTEM

摘要

The invention concerns a system designed to actively reduce radial vibrations in a rotating shaft (4), in particular the drive shaft of an internal-combustion engine (1), the system having at least one electromagnetic device (7; 10; 15, 16) which is designed and controlled so that it applies to the shaft (4) radial forces which counteract radial vibrations in the shaft (4).
