Nanomotion's Miniature Micropositioning Rotary Stage
Date: 25 October 2011
Nanomotion's new FBR60 piezo-electric miniature rotary stage is now from available from Heason Technology.
Providing an exceptionally compact
footprint and low profile for precision motorised rotary
positioning, the stage has a 60 mm diameter rotating element and
overall height of just 35 mm and features a high-stiffness cross
roller bearing construction, twin piezo-electric motors that
provide zero backlash direct-drive, and an integral non-contact
optical encoder with micropositioning resolution options of 5 or
0.5 arc-sec.
Available in standard, vacuum and UHV versions, the FBR60 has an
overall accuracy of 10 arc-sec with speeds to 360 degrees/sec and
direct load capacity to 5 kg. A central through aperture may used
for underside cable or services entry for user devices, which are
conveniently mounted on the rotating platen via a matrix of M2.5
threaded holes. The stage may be used independently or as a part of
a multi-axis positioning set-up with Nanomotion's FB series linear
and goniometric stages allowing nanometre level translation for all
six degrees of freedom.
Nanomotion's ceramic motor technology has no intrinsic magnetic
field or moving parts and is well suited to ultra-clean and vacuum
environments such as those found in semiconductor, biomedical and
photonics automation systems. Ceramic motors feature an inherent
braking and holding capability and are well proven where high
dynamic performance motion control calls for fast settling times
and optimum in-position stability.
Nanomotion's HR series high force ceramic motors are used
throughout the FB range. A complete range of dedicated 20 kHz servo
drives are also available from Nanomotion, and Heason also offers
other compatible drives together with a complete range of motion
controllers for nano scale linear and rotary positioning.
