Beschreibung
Zusammenfassung:	The invention concerns a method for stabilizing the motion of an articulated chain of a chain block, especially to prevent the formation of resonance oscillation of the chain, in which an articulated chain is led across a polygonal chain wheel with non-uniform pitch, which is driven by an electric motor. In order to create a method to prevent the formation of a resonance oscillation of the articulated chain, it is proposed that a periodic and/or stochastic and dampening actuating variable is superimposed on the velocity of the chain wheel ( 4 ) and the dampening actuating variable produces a change in the chain velocity so as to prevent a formation of a resonance oscillation. The chain drive with reduced polygon effect is characterized in that an electronic damper ( 8 ) is hooked up in front of the electric motor ( 2 ), which produces a control of the electric motor ( 2 ) such that a formation of a resonance oscillation of the articulated chain ( 5 ) is prevented.
