The design of the ADRS series direct-drive rotary stage was optimised to minimise stage height. The low profile of the stage reduces the effective working height of the system, minimising “stack-up” related errors. In addition to the low overall height, the ADRS series provides a clear aperture that can be used for product feed-through or laser beam delivery.
To maximise positioning performance, the ADRS rotary stage series utilises direct-drive brushless motor technology. Direct-drive technology is optimised for 24/7 production environments as there are no brushes to replace and no gear trains or belts to maintain. Direct drive also provides quicker acceleration and higher top speeds than gear- or belt-driven mechanisms, yielding higher total overall throughput.
The ADRS series of rotary stages uses a slotless stator design that eliminates torque ripple. This motor technology provides ultra-smooth velocity stability comparable to a high-quality DC brush motor without all the DC motor’s inherent maintenance requirements. Since the slotless motor is directly coupled to the tabletop, velocity disturbances created by toothed belt drives or worm gears are eliminated.
The ADRS series is available in 100mm, 150mm and 200mm versions. Each stage has options for different motor windings to better match the stage to different operating conditions. The -B winding option provides the highest possible speed operation for a given available bus voltage, while the -A winding gives greater output torque for comparable current levels. Metric and “English” pattern tabletops are available and slotted mounting holes enable attachment to 25mm and 1-inch hole pattern breadboards. The tabletop of the ADRS series has a labyrinth seal that protects the bearings and encoder from contamination. An optional shaft end-seal is available for applications where the bottom of the stage is exposed to contamination.
Design Features of the ADRS Rotary Stages Include:
High torque output, direct-drive brushless servomotor
Cog-free slotless motor design for outstanding velocity stability
Direct coupled, high-accuracy rotary encoder
Ultra-low-profile minimizes working height
