Motorized Dual-axis Alpha-Beta Goniometers Mounted on Single-axis X-axis

Home > Assorted Motorized Multi-axis Actuators

 

The XAB-xxxx-20-30-01 integrates a two-axis Alpha-Beta goniometer on top of a single-axis linear actuator. The Beta-axis has a travel range of +/- 15 degrees with a rotation height of 50 +/- 0.2 mm. The size of the table is 65 by 65 mm (2.559 by 2.559 inches). The gear ratio is 1 degrees (stage) : 252 degrees (motor). The travel guide is precision crossed-roller guide.
The lower goniometer (Alpha-axis) has  +/- 10 degrees of rotation driven by a worm gear with a drive ratio of 352 degrees of motor rotation to 1 degree of stage rotation.

The Alpha and Beta axes have  a caliber indicator to display the angle of rotation which is ideal for: Crystallography, metrology, light measurement, measurement of surgical cutting blades, microscopy, laser positioning, and inspection applications.

The threaded mounting holes in the Beta-axis and mounting holes in the X axis assure easy integration into new and existing applications.

T
he XAB-xxxx-20-30-01 features Two Phase Stepper Motors with knobs for manual adjustments which can be replaced with optical encoders for position verification.  The XAB-xxxx-20-30-02  is driven by Three Phase Brushless Servo Motors with Quadrature Incremental Optical Encoders for closed loop operation that offer the highest resolution, repeatability, and travel speeds.

Both stages can be ordered Plug-and-Play with a fully compatible
Motion Controllers.
