These four AU270-AER Three Axis Gimbal Mounts were developed to be used with larger and heavier: Cameras, telescopes, directional antennas, optics, lasers, tracking and scanning systems. These new, larger, high stability, gimbal mounts are 400 mm wide x 480 mm high, weigh 50 kg and handle loads up to 10 kg. This series accommodates an aperture hole of 30 mm.
The Azimuth, Angular Elevation, and Roll Stages of the AU270-AER all feature high precision 100 mm diameter rotary stages. The Roll Stage has a precision pattern of threaded holes for mounting tooling, cameras, lasers, etc., and a through hole for cables and optics. Devices up to 260 mm wide can be mounted on the rotary stage. Each stage features V-groove and crossed roller bearings, capable of 360 degrees of continuous rotation and driven by a 180:1 worm gear. Motor options to power each stage include: Two Phase-Stepper Motors (AU270-AER-01), Three Phase Brushless Servo Motors with Quadrature Incremental Optical Encoders (AU270-AER-02), DC Servo Motors with Quadrature Incremental Optical Encoders (AU270-AER-03), or Two-Phase Stepper Motors with Quadrature Incremental Optical Encoders for position verification (AU270-AER-04). Electrical connections are made using 9 pin DB-9 connectors.
The knobs of the stepper motors may be replaced with optical encoders for position verification.
The resolution of each stage is 0.001 degree or 3.6 arcsec with 10 micro-steps per Step Motor Driver in use. Higher resolutions and travel speeds to 45 degrees per second are possible with the servo motor options.
An optional 450 mm x 450 mm aluminum plate with four handles and mounting holes for increased stability is available and these.
An Elevation and Roll Axis version of this gimbal is available.
The AU270-AER Motorized Three-axis Gimbal Mounts require a
Motion Controller
that can be ordered as a complete plug-and-play system with joystick, trackball, and keypad.
