Design Features

  • Integrated, low-profile, XY, linear-motor stage with clear aperture
  • Excellent geometric performance (straightness to ±0.5 µm, flatness to ±1.25 µm)
  • Optimized for high-dynamic applications
  • Speeds to 2 m/s and accelerations to 2g
  • Integrated cable management
  • Large selection - nine models in travel and accuracy

Ultra-Precise Stage Design

The PlanarDLA XY design provides for unparalleled planar geometric performance in applications where straightness and flatness of motion are critical. High-precision roller bearings, precision-machined surfaces, and noncontact direct-drive linear motors driving through the axes’ center-of-stiffness result in a positioning stage with exceptional geometric tolerances (straightness to ±0.5 µm and flatness to ±1.25 µm).

The PlanarDLA structural elements are optimized for high dynamics and high stiffness for the most demanding dynamic applications. With this optimized design, the PlanarDLA achieves high servo bandwidths while at the same time maximizing the clear aperture available and keeping the overall height to a minimum. Capable of achieving 2 m/s velocities and 2 g accelerations, the PlanarDLA enables high-throughput, high-accuracy processing resulting in superior process yield, and a low total cost of ownership.

Noncontact Direct-Drive Technology

Only noncontact, direct-drive technology offers high speed and accurate positioning coupled with maintenance-free operation and long service life. At the heart of the PlanarDLA is Aerotech’s proprietary direct-drive technology. This drive technology allows for unmatched performance compared to other competitive screw-based and linear motor designs.

All PlanarDLA stages are available with one or two motors per axis allowing optimization of each individual axis for the specific application and process. With two motors, the resulting drive force acts through the centers of friction and stiffness resulting in superior geometric performance and accuracy, while one motor per axis provides for a more economical choice if high-throughput and the strictest positioning performance is not required.

Variety of Cable Management Options

The standard cable management system on the PlanarDLA is integrated into the stage and optimized for long life and performance. Several standard options are available for additional servo axes, air/vacuum lines for vacuum chucks, or other process pneumatics.

Extreme Positioning Performance

The PlanarDLA is available in three positioning performance options. Relying on decades of experience in system-level design including not only positioning mechanics, but also software and electronics, Aerotech has developed advanced technologies to push the envelope of precision. High-performance -PLUS and -ULTRA options are available to enable accuracies and straightness values down to ±500 nm and orthogonality down to 5 µrad.
