The single bearing positioning stage is designed for long-stroke,
high-acceleration closed position loop servo applications.
The small cross section single bearing positioning stage
features a moving coil 3-phase cog-free brushless motor with
single rail, two integral linear bearings and encoder. The
stage features lightweight moving parts for higher acceleration
of light loads. An open linear glass scale is available to
meet customer requirements. Resolutions available are 1 and
5 micron.
The cog-free brushless linear motor provides smooth, high
reliability, non-contact operation without backlash. Excellent
dynamic and settling time performance is a result of the superior
stiffness of brushless motors.
Single bearing positioning stages can be stacked on top of
each other to provide a multiple axis positioning system.
Typically, a wider cross section is used as the base axis
for stability and stages with smaller cross sections stacked
on top.
