Nutec Corp. has upgraded its TMAX 5 low-profile, direct-drive
rotary servo positioning stage for higher load capacity and improved trajectory
control. Applications include laboratory testing, laser machines, optical metrology,
and photonic and optical testing and manufacturing. Driven by a brushless servo
torque motor with a high-resolution rotary encoder system, the stage provides smooth,
low-friction rotary motion with 360° continuous travel, low hysteresis, low
noise and low vibration. Accuracy is within 25 arc sec, wobble is ≤8 arc sec,
concentricity is ≤4 μm, and flatness of rotation is ≤6 μm.
High-precision options reduce these specifications to 1 μm. The stage is constructed
with a monolithic rotating hub (from 50 to 200 mm in diameter) suspended by a preloaded
bearing system with duplex angular ball bearings for good angularity and stability,
good dynamic characteristics and unlimited service life, even at maximum loads.
