These Elevation and Roll Gimbal Mounts are ideal for mounting: Cameras, antennas, projectors, lasers and instrumentation for scanning, tracking, positioning optics, and other applications.
Each axis of the gimbal mount features: Low backlash worm gear drives and precision "V" groove and cross roller bearings for very high repeatability and positional accuracy. Available with either stepper motors (AU300-AE-01 pictured) or with three-phase brushless servo motors with Quadrature Optical Encoders (AU300-AE-02) for greater resolution, accuracy, and repeatability as well as higher travel speeds.
The gimbal is mounted on a large 360 mm (14.173 in.) x 360 mm (14.173 in.) x 13 mm (0.512 in.) plate for increased stability and the elevation (pitch) axis has a clearance of 300 mm x 300 mm, (11.8 in. x 11.8 in.) around the roll axis stage. The elevation table has a precise pattern of threaded mounting holes for fixtures, tooling through hole.
Each AU300-ER Series Roll and Elevation Two-axis Gimbal Mount handles loads to 10 kg (22 lbs), and the base plate has four handles and accessible predrilled mounting holes for easy integration into new or existing applications. The travel speeds of each axis are 12 Degrees per second with stepper motors and 45 Degrees per second with servo motors. Electrical wiring is enclosed for protection and connections are made using 9 pin DB-9 connectors.
The knobs of the stepper motors may be replaced with optical encoders for position verification.
A
Three-axis
version
is also available.
The AU300-AE Motorized Two-axis Gimbal Mounts require a
Motion Controller
that can be ordered as a complete plug-and-play system with joystick, trackball, and keypad
