<p>The aim of the invention is to provide a drive device for producing a to-and-fro motion of driven part, particularly in weaving machines, which is characterized by having a high degree of efficiency and good dynamic properties with regard to the respective and, optionally, even changing operating conditions. To this end, the drive device comprises: a drive source (2), which is coupled to a part (50) and which produces the to-and-fro motion; an energy accumulator (22), which is assigned to the part and/or to the drive source and which is provided for accumulating potential energy during at least one portion of the to-and-fro motion of the part, and; a control device (20) for controlling at least the energy accumulator and/or the drive source according to measured and/or predetermined parameters for the course of motion of the part.</p> |
