Noncontact Direct-Drive

Only noncontact direct-drive technology offers the robust, accurate and high-speed positioning necessary for mass production of precision devices. ANT stages utilize advanced direct-drive technology pioneered by Aerotech to achieve the highest level of positioning performance. This direct-drive technology is high-performance, non-cogging, noncontact, high-speed, high-resolution and high-accuracy. The unique drive and bearing combination, packaged in an extremely small-profile and footprint, offers tangible advantages in many applications such as high-precision positioning, disk-drive fabrication, fiber alignment, optical delay element actuation, sensor testing and scanning processes that demand smooth and precise motion.

Flexible System Design

The ANT family has universal mounting and tabletop patterns that allow for easy system integration. Two, three or more axes can be easily combined for flexible system designs and multi-axis configurations. Options include precision orthogonality alignment to 5 arc seconds and vertical axis solutions. We include all customer-required cables, air hoses, etc. in our CMS bundle to facilitate incorporation into the final system. Both ends are fully connectorized for simple integration into the customer’s machine.

System Characteristics

Outstanding accuracy, position repeatability and in-position stability require high system resolution. The ANT stage’s industry-leading 1 nm minimum incremental step size provides this high level of performance. Aerotech’s direct-drive technology has no hysteresis or backlash, enabling accurate and repeatable nanometer-scale motion.

Designed for Long Life

Like all stages in the Aerotech product family, the ANT was designed for outstanding long-term performance. Both the linear motor and linear encoder are noncontact devices, which means they not only exhibit long-life but are totally maintenance free.
