Abstract

An assembly of motors designed to drive a ring rail, a bank of spindles and a plurality of draw or delivery rollers in a ring spinning or twisting machine is supplied with three-phase current of a frequency determined by the settings of digitally adjustable frequency selectors independently controlling respective solid state frequency-inverters assigned to the several motors or groups of motors. The selectors include frequency dividers in the output of a common and preferably also adjustable source of timing signals which may be a free-running oscillator or a pulse generator driven by one of the motors acting as a master.
