ALAR Series Direct-Drive Rotary Stages

Aerotech, Inc.

ALAR series direct-drive rotary stages provide superior angular positioning and velocity control with exceptionally large apertures, load capability, and very high speeds. With the combination of a large aperture and direct-drive motor, the ALAR series offers significant performance benefits compared to worm-drive large aperture stages.

One Belt for the Load

This Harmonic Linear Drive uses a recirculating belt to move a load-carrying traveler with fewer parts than other belt-driven systems. As the animation

illustrates, the belt, folded back upon itself, is routed over pulleys of slightly differing diameters. This, in turn, provides a gear reduction without the cost or backlash of a separate gearhead.

The New PLC?

How would you like to simplify your next automation project by "combining control and HMI into One PC-Based Platform?" Changes in industrial PC's over the last decade suggest they are ready for the job. Besides system and economic advantages, working from a single platform would simplify hardware installations.

Follow the Straight, Circular Path

Laser machining involves a variety of processes that must perform in complex patterns at high velocities while maintaining acceptable tolerances. Tracking errors in the motion system will diminish final part quality. Employing concepts such as acceleration limiting and multi-block look-ahead will allow you to maintain high throughput as well as high quality.

For these Sensors, All Metals are Equal

To detect different ferrous and nonferrous materials at varying ranges, most inductive proximity sensors must be adjusted to accommodate a correction factor. Then there are Factor 1 sensors from Turck: Factor 1 sensors detect all metals at the same range without adjustment and have a longer sensing range than regular proximity sensors.

Vector Quad Linear Guide System

Modern Linear Incorporated

The Vector Quad incorporates standard v-groove guide rollers and track in a patent-pending, compliant design. The compliant design feature eliminates the need for carriage set-up or adjustment. It has a low profile and the four roller carriage offers good load capacity in all directions. This design is ideal for single rail applications.

Why "Print" is Alive and Well Today

When it comes to explaining the synchronizing capabilities of motion control, there may be no better example than today's modern printing presses. Such machines may include as many as 100 axes, all controlled by servo motors, stepper motors, and "hybrid architectures of daisy-chained controllers or PLCs." Motion Control online explains how "electronic line shafting" gives operators the ability to move various print modules on and offline while maintaining web tension, color registration, roller speed, and multiple other variables. All reasons why the process of printing, despite the Internet, is "alive and well" today.

Compact AC Drives for High Starting Torque Applications

Omron Electronics LLC

Omron's AC drives with open loop vector control 3G3MX series support applications such as mixers, compressors, and conveyors with high starting torque of 200% at 1 Hz. Side-by-side mounting saves panel space. Built-in functions suppress nuisance alarms and enable auto restart after power loss. Visit us for specifications or brochure.
