Abstract: 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.

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.

Abstract: Force in a direction opposite to an operating direction imparted from a motor to a rotary knob is increased gradually at the start of an operation to an upper limit value with the increase of a rotating angle of the rotary knob in the same direction as the operating direction, and is gradually decreased at the finish of the operation from the upper limit value to 0 with the increase of the rotating angle in the opposite direction to the operating direction. In consequence, when the operation is stopped before or at the time at which force in the opposite direction to the operating direction imparted to the rotary knob reaches the upper value, the rotary knob returns to the angle at which it has existed before operated, and can come to halt without oscillation.
