Rotative direct drives are increasingly replacing conventional gearbox solutions in a lot of applications. The omission of gearboxes, belts or spindles produces a system free of play. Increased system rigidity enables high dynamic acceleration and very precise positioning, significantly reducing cycle times. The speed of the driven machine corresponds to that of the drive. Specifically in the case of very low or high speeds, annoying gearboxes losses are omitted. Direct drives operate quietly and are free from wear and maintenance. With its high torques and flat design, the permanent magnet excited synchronous motor from ZIEHL-ABEGG impresses in an array of versions.
