Aerotech Direct-Drive Linear Stage
Direct-drive linear stage.
Pittsburgh, PA — Aerotech ANT130-L series stages are described as offering best-in-class performance in speed, accuracy, resolution, repeatability, reliability, and travel range, and are offered in two accuracy grades. With its low profile and high performance, these stages provide an excellent solution for high-accuracy alignment, inspection, positioning, and measurement stations.

The stage uses a center-driven, non-cogging, noncontact linear motor and encoder as the driving element. Since the linear motor is a direct-drive device, there is no backlash, windup, or "stiction" normally associated with a lead- or ball-screw drive.

The linear motor drive also offers the advantage of higher speeds and accelerations. The compact yet powerful linear motor drives the ANT130-L to a peak unloaded acceleration of 1g and a maximum velocity of 350mm/s. The result is a high-accuracy device with outstanding dynamic performance, with throughput that significantly outperforms comparable high-accuracy screw-driven or other stages in its class.

The ANT130-L meets the demand for high resolution with an incremental step size of 1nm when coupled with the company's drives and controls. The direct-drive linear motor allows the ANT130-L to make precise, small resolution steps, which is particularly important in alignment applications where step accuracy is critical.
