Description

Design Features

Direct-drive linear motor for ultra-precise motion
Long-life linear motion guide bearing system
Two-axis internal cable management system
Sealed design with optional air purge
Low-cost, small footprint, high-performance stage

The ALS1000 is a compact, high-performance stage that is as accurate as it is versatile. It provides a small cross section, large payload capacity, cost-effective solution for precision applications where a small footprint and environmental protection are required. A linear motion guide bearing system, two-axis internal cable management and high-performance brushless servomotor make the ALS1000 the stage of choice in industrial applications such as laser machining, medical component manufacturing and other applications requiring high accuracy in a production environment.

Construction Features

Sealed linear motion guide bearings with integral wipers are incorporated to provide excellent payload capability and long life. Both the metal waycover and tabletop are treated with a hardcoat (Rockwell 62 hardness) that is scratch-resistant and provides outstanding protection in the harshest applications. An optional air-purge fitting is available that allows air to be forced into the body of the stage to create a positive internal pressure that resists particulates from entering the stage. The tabletop utilizes stainless steel Helicoil™ inserts to protect mounting holes against thread wear.

Linear Motor Drive

Aerotech’s high-power, cog-free, BLMC series linear motor drives the ALS1000. The non-magnetic forcer coil provides high force with zero cogging for super-smooth velocity and position control. This zero cogging design is ideal for applications requiring outstanding contour accuracy and smooth velocity profiling. As with all of Aerotech’s ALS series linear motor stages, the linear motor has zero backlash, no windup, zero friction and outstanding system responsiveness.

Cable Management System

The ALS1000 features an optimized cable management system (CMS) that is designed for millions of cycles of maintenance-free operation. In single- and two-axis systems, the CMS is completely internal. External CMS is available for three-axis systems.

High Performance

Noncontact linear encoders are standard on all ALS1000 series stages. Either a line-driver output or amplified sine-wave output encoder is available. Motor power and feedback signals terminate in the stage endplate allowing for a simple, clean interface.

The optional HALAR factory calibration further increases the standard accuracy and repeatability. Aerotech manufactures a wide range of matching drives and controls to provide a fully integrated and optimized motion solution.

Aerotech offers both standard and custom integration services to help you get your system fully operational as quickly as possible. The following standard integration options are available for this system. Please consult Aerotech if you are unsure what level of integration is required, or if you desire custom integration support with your system.

Option	Description
-TAS	Integration - Test as system Testing, integration, and documentation of a group of components as a complete system that will be used together (ex: drive, controller, and stage). This includes parameter file generation, system tuning, and documentation of the system configuration.
-TAC	Integration - Test as components Testing and integration of individual items as discrete components that ship together. This is typically used for spare parts, replacement parts, or items that will not be used together. These components may or may not be part of a larger system.
