Direct Drive Precision Stages
High Performance in a Compact Package
Parker Bayside's Direct Drive Rotary Stage, featuring an integral brushless
DC servomotor, has several distinct advantages over traditional worm
gear-driven stages. The elimination of the worm gearing offers the ability to
reduce wear with zero backlash while exhibiting near frictionless motion.
Its high positioning accuracy, solely based on the stage's encoder, provides
repeatability within + 2 encoder counts, with resolutions ranging to 1.4
arc seconds. The RD Direct Drive features speeds up to 700 RPM with
significant torque capability.
