Aerotech AMG LP Gimbal

Provides ultra-precise angular position, rate and accelaration

Aerotech

Aerotech's new AMG LP (Low Profile) position and rate gimbal mounts provide ultra-precise angular position, rate and acceleration for development and production testing of a wide range of systems. 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. The AMG LP gimbal design incorporates recent Aerotech rotary stage design improvements to provide high performance at an affordable price. The finest quality motors, bearings and encoders are integrated into precision-machined housings to ensure peak performance. The AMG position and rate gimbals provide precise angular motion with the high performance customers expect from Aerotech products.

Features:

  • Continuous 360 degree rotation of azimuth and elevation including built-in slip ring
  • High accuracy angular position and rate capability
  • Direct-drive brushless servomotors result in zero backlash
  • Cog-free design for outstanding velocity stability
  • Accommodate loads up to 200mm in diameter
  • Low maintenance and high reliability provide the lowest cost of ownership

Low Profile
By incorporating our low profile direct-drive rotary stages, the LP series is capable of speeds and accelerations that are significantly higher than other competing products of this size. These gimbals have a lower profile compared to competing products within given torque ranges. This results in a smaller and more effective gimbal for many applications where beam height and chamber volume are of utmost concern. Customers with only limited azimuth travel requirements can have the slip-ring removed for an even lower overall height. Keeping the optical path lower helps improve overall test accuracy. Based on the ADRS rotary stage, the AMG LP provides a high accuracy, smooth motion solution with low maintenance and high reliability.

Accurate 360° Positioning and Rate Generation
Direct-drive brushless torque motors, with rare-earth magnets and high-accuracy angular transducers are coupled directly to precision shafts for accurate and smooth 360° 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 highly accurate and repeatable positioning.

A wide-range of performance feedback grades is available. Typical line gimbal resolution ranges from 0.87 to 0.32 µrad with Aerotech controls. Built-in azimuth slip ring provides for continuous rotation with no cable wrap up.

Superior Mechanical Design Features
High-quality, low-profile bearings maximise performance with respect to wobble, moment stiffness and rotating friction. Travel limits and hardstops, and brakes are available as standard options.
