Motorized Two-axis Gimbal Mount, Azimuth and Elevation  Axes
(Yaw and Pitch Axes)

Home > Assorted Motorized Gimbal Mounts


 

These three-axis, Azimuth, Elevation, 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-AER-01 pictured) or with three-phase brushless servo motors with Quadrature Optical Encoders (Au300-AER-02) for greater resolution, accuracy, and repeatability as well as higher travel speeds. 

The azimuth (yaw) axis 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 and roll tables have a precise pattern of threaded mounting holes for fixtures, tooling. The roll axis has and a centered 30 mm (1.181 in.) through hole.
 
Each  AU300-AER Series Azimuth and Elevation Three-axis Gimbal Mount handles loads to 0kg (22 lb), and  the base plate has four handles and accessible predrilled mounting holes for easy integration into new or existing applications. Travel speed 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.

The AU300-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.
