Description

Design Features

High-performance in a cost-effective, economic package
Rugged mechanical design
Direct-drive linear motor for precision motion
Nine models with travels from 100 mm to 800 mm

The ECO225LM series, part of the ECO linear stage family, builds upon Aerotech’s long tradition of producing low total cost of ownership motion designs. Excellent positioning specifications, high stiffness and load capacity, and a variety of options and features combined with economic pricing make ECO225LM stages an ideal choice for medium-performance production applications.

Quality Mechanical Construction

A long-life recirculating linear guide bearing system and quality construction make the ECO225LM an attractive solution for applications where up-time is critical. Unlike low-cost competitive motion stages, the ECO225LM can be integrated into complex machines with the assurance it will perform at a high level and outlast other machine components.

Precision Motion Performance

ECO225LM series stages are optimized with high precision, noncontact linear encoders. Precision recirculating linear bearings, along with Aerotech’s machining and assembly craftsmanship, enable the best geometric performance per unit price on the market.

The precision noncontact encoders enable minimum incremental motion to 10 nm with micrometer-level repeatability. The optional HALAR factory calibration improves positioning accuracy to ±1.5 µm.

Direct-Drive Linear Motor

The ECO225LM comes standard with Aerotech’s field-proven linear motor technology. It is available with a high-performance linear-motor option for applications requiring higher force and acceleration motion profiles. In both cases the ironless forcer coil provides high force with zero cogging for super-smooth velocity and position control. This ironless design is ideal for applications requiring outstanding contour accuracy and smooth velocity profiling. As with all Aerotech linear motor stages, the linear motor has zero backlash, no windup, zero friction, and excellent dynamic responsiveness.

Design and Integration Flexibility

The ECO225LM is available in nine different models with travels ranging from 100 mm to 800 mm and speeds up to 2 m/s. Configurable cable management solutions are available for single and multi-axis systems as standard options.

The base mounting holes are accessible from the outside of the stage for easy mounting. Standard mounting holes for both English and metric optical tables are present in all travels. Tabletops are available with both English and metric mounting patterns. Tabletop hole patterns allow the direct attachment of several types of Aerotech rotary stages.

The ECO225LM stage is a flexible, yet cost-effective, linear motion stage with many options to fit the exact needs of the application. It is easily the best performing and most versatile linear stage per unit price that money can buy.
