ATS0300 Mechanical-Bearing Lead-Screw Linear Stage

Description

Design Features

  • Precision-ground, high-accuracy lead screw
  • Ultra-fine resolution
  • Crossed-roller bearings for high load capacity and smooth motion
  • Includes cogless, brushless servomotor
  • Compact profile

The ATS0300 provides an economical solution for applications requiring fine positioning in a confined area. ATS0300 series stages feature bases made from a special aluminum alloy tooling plate for good stiffness and long-term stability. Other high quality features are crossed-roller linear bearings for smooth travel and excellent payload characteristics, a precision-ground lead screw for high accuracy and hardcoat treated base and table for high resistance to marring and scratching. Table mounting holes have Helicoil stainless steel inserts to permit multiple screw insertions without thread wear.

The ATS0300's precision-ground lead screw is available in both metric and English leads. A fine pitch screw results in submicron resolution.

Multi-Axis Combinations

ATS0300 series stages are easily configured in XY, XZ or XYZ arrangements. The precision-machined HDZ3 right angle L-bracket is designed for Z-axis applications and the HDT3 bracket is ideal for lower profile configurations.

Options

Both metric and English mounting and bolt-hole patterns are available. A large thru-hole aperture version is available that is ideal for applications requiring backlighting. As is the case with all ATS series stages, the ATS0300 may be vacuum prepared to 10-6 torr.

Motors and Drives

The standard motor included with the ATS0300 is Aerotech's BMS series brushless, slotless motor. This motor utilizes an ironless design so there is no cogging, which results in no torque ripple throughout the range of motion. Aerotech's amplifiers and controllers range from easy-to-use point-to-point indexers to sophisticated multi-axis contouring controllers. Form factors include stand-alone controllers with RS-232 and IEEE-488 interfaces, to the advanced software-based Automation 3200.
