Aerotechs Latest Gimbals Ensure Zero Backlash
The AMG LP series is ideal for directing optics, lasers, antennas, and sensors at high speed to precise pointing angles. Typical applications include missile seeker test and calibration, electro-optical sensor and FLIR testing, optical testing of sensors in a vacuum, and angular testing of inertial sensors such as gyros, MEMS, and accelerometers.
According to the companys press release, the LP series is capable of high speeds and accelerations and have a lower profile compared to competing products within given torque ranges. This results in a gimbal suitable for many applications where beam height and chamber volume are of concern. Customers with only limited azimuth travel requirements can have the slip ring removed for an even lower overall height.
Direct-drive brushless torque motors, with rare-earth magnets and high-accuracy angular transducers, are coupled directly to precision shafts for 360 degree continuous motion. The absence of gear trains and other drive mechanisms eliminates position error contributions due to mechanical hysteresis and backlash. Directly coupled high-resolution position transducers ensure more accurate and repeatable positioning. A built-in azimuth slip ring provides for continuous rotation with no cable wrap up.
