Module puts Rockwell controllers on the Web
The Allen-Bradley 1756-EWEB module from Rockwell Automation, Milwaukee supports Ethernet/IP and offers a suite of Web capabilities for ControlLogix controllers.
GM standardizes on Ethernet/IP
General Motors Corp., the world's largest vehicle manufacturer, recently standardized on the Ethernet/IP network for its vehicle manufacturing operations. The network is slated to provide real-time communication between machine controllers, robots, process-control equipment, and provide information to higher-level business systems. GM suppliers in America, Europe, and the rest of the world have until January 1, 2007 to make their products Ethernet/IP compatible.
Rodless rail slides
Rail-bearings provide smooth, precise linear motion within confined spaces in new Series SFP slides.
Ball screw basics
The pros and cons of single and double-nut balls screws.
Getting the right angle
Angle encoders differ from standard duty rotary encoders in terms of accuracy as well as mechanical complexity and the number of counts per revolution.
Leadscrews roll over ball screws
Leadscrew technology has made vast strides. Now, leadscrews offer higher performance at lower cost.
Grippers pack long stroke in tiny package
The GD500 series of three-jaw grippers use a piston-drive cam mechanism to deliver relatively large strokes from a small device.
Drives cut downtime
Ac drives relieve dc motor and drive service issues.
Managing multiaxis motion
Servodrives synchronize rotary and linear movements.
Bump and grind
Robotic crash-protection devices take their lumps and come back for more.
Mars Rover to Earth: "Where to now?"
Harmonic drives boost pointing accuracy in high-gain antenna drives aboard Mars Explorer Rovers.
Ready, aim, shoot, send
Embedded systems for digital cameras are being asked to do more. Soon, wireless links will be de facto features.
Microstepping myths
The lure of microstepping a stepper motor for precision must be tempered by torque considerations.
Motors bring Mars mission to life
Small, efficient motors help NASA search for signs of life on the Red planet.
Testing motor brushes for space
NASA considers several qualities of motor-brush materials when determining suitability for a given mission. Among the most important are the wear rate and the cohesiveness of the debris. Engineers note if there's a tendency for brush debris to pack into commutator slots.
