Offering positional accuracy to 1.5 arc-sec, the Aerotech's APR mechanical bearing series has an axial load capacity up to 450 kg. Covering seven models, it comes in three frame sizes with nominal square footprint mounting dimensions of 150, 200 and 260 mm, offering a clear through-aperture of 50, 75, or 100 mm respectively. Building on Aerotech’s previous performance characteristics for direct-dirve/mechanical stage construction, the series include total tilt error motion of 2.0 arc-sec with total axial and radial error motion of just 1.5µm. Other specifications include 0.04 arc-sec resolution and 0.75 arc-sec bidirectional repeatability on certain models. The direct-drive brushless servo motor is cog-free, allowing smooth velocity performance with rapid acceleration and maximum speed up to 800 rpm for smaller stage. Available for individual single axis use, combined for rotary azimuth/elevation positioning system, the series can be used in applications where the centre of rotation is either parallel or perpendicular to gravity. The range includes standard and calibrated accuracy options, incremental or absolute encoders and a choice of direct-drive motor ratings to match load, torque and speed requirements. It can be supplied for continuous rotation or fitted with limit switches for part rotation from 10 to 270°. Further options include brakes and adjustable mechanical hard stops to restrict rotation up to 290°. The housing and construction is anodized aluminum with a durable hard coat finish. An optional tabletop includes a matrix of threaded holes for customer work piece interfacing. With its non-contacting motor and encoder and long life bearing system, the series is rated for 20,000 hours MTBF and requires minimal maintenance. Single- or multi-axis motion control solutions for the series include PC based software-only or hardware based rack or desk mount packages with advanced motion commands that optimize performance, reduce commissioning times, increase throughput and enable higher quality finished parts or test quality. A wide choice of programming options include RS-274 G-code, AeroBasic, IEC61131-3, Microsoft .NET Framework and LabVIEW.
