ABSTRACT:
A drive system for a printing press having a DC drive motor which is supplied, via an inverter, from an AC supply line. A flywheel assembly is connected to at least one of the rotational elements of the press, the flywheel assembly including a flywheel and short torsionally resilient rod coaxially interconnecting the flywheel and the rotational element and rigidly connected at its ends to each of them, with the rod and the flywheel together being so proportioned as to form a resonant mechanically oscillating system having fundamental resonance at the frequency of the supply line.
