Precision motion in high-throughput industrial automation often involves repetitive moves with increased loads and accelerations.
The V-817 Series Precision Automation Stage Assembly, featuring a direct-drive rotary table, showcased above, offers high acceleration and duty cycle motion. It utilizes efficient 3-phase linear motors and torque motors, providing substantial continuous and peak force.
The robust stage construction, crafted using aircraft-grade aluminum alloys, ensures the required stiffness to manage high impulses over short durations while maintaining precision.
Employing precision truck and rail bearings further enhances load characteristics and extends operational lifetimes. The integrated high-speed direct-drive rotary stage, with its significant torque output, is pivotal for dynamic step-settle and scanning performance.
PI XY-Theta automation systems are tailored to specific applications, considering travel, performance, load, and space requirements.
The showcased solutions here provide a glimpse of the available options for XYT motion, highlighting the varied assortment of motor, bearing, encoder, and design components that have contributed to PI's status as a market leader in precision motion.
