Abstract:
System for active dampening of vibrations of the drive shaft of an internal combustion engine, by means of an electric machine, which has two active electromagnetic units that can rotate relative to each other, one of which is connected to the rotating shaft and the other is secured against turning or--alternatively--connected to another rotating shaft, wherein one of the active units comprises at least two electrically independently actuable active sectors for generating traveling fields, each of which exerts forces with radial and tangential components on the other active unit, such that the electric machine dampens both radial and rotational vibrations of the shaft.
