Aerotech – Elevation over azimuth positioning gimbals and opticsOct 20 2005 - Test & Measurement [More Test & Measurement Articles]
A new 8-page brochure, which highlights its complete range of gimbals and
optical mounts for high-precision elevation over azimuth positioning
applications, has been published, by Aerotech.
Aimed at demanding research and manufacturing applications including mirror
positioning, beam steering, target/star tracking, inertial gyro calibration
and sensor testing, the range includes a choice of drive systems including
brushless direct-drive, conventional servomotor or stepper motor drives with
geared transmission and manually driven variants.
The new brochure is available on request in hard copy or as a downloadable
PDF from the company´s website. The brochure is available in both English
and German language versions.
The gimbals and mounts are built to exacting standards with a strong
emphasis on highest precision bearings and finest quality machined housings
to ensure superior stability. Direct-drive versions are preferred for the
highest precision and most exacting applications. Direct-drive rotary
technology eliminates the need for mechanical linkages, couplings, ball
screws or gearboxes and when used with high precision feedback devices
allows a significant improvement in accuracy and repeatability with further
benefits of zero backlash, reduced vibration, lower noise and zero
At the top end of the range, the two axis AOM360D series gimbal will
position to within +/- 1 arc-sec with a resolution of 0.055 arc-sec.
Backlash-free, direct-drive brushless servomotors ensure 300 degree/sec
speed performance with exceptional smoothness and high acceleration. Mirror
or payload diameter is up to 500mm with a 50 kg load capacity. The AOM360D
has a thermal stability of better than 0.4 arc-secs per OC and industry best
orthogonality and wobble specifications of just 3 arc-secs.
The new brochure also features the new direct-drive brushless AMG series
gimbal in a choice of seven models for 150mm to 600mm diameter mirrors with
varying attributes to match the elevation over azimuth application
specifics. These include models with superior high-speed performance for
fastest tracking through to highest resolution for finest positioning. The
range also covers models aimed at solving applications requiring high
torque, small footprint, low profile, low jitter, smooth scanning and large
payload capability.Electropages - Electronics Components News, From Leading Electronics Distributors. More news from Aerotech
