This board is made for microstepping for stepper motors. It can attach directly to the controller's 96-pin DIN connector, with no cables required, and Galil's SDM-20620 works well with 2-axis applications. The SDM-20640 measures 6.92 × 5.10 inches. It includes four microstepping drives on one board, each capable of driving a two-phase bipolar stepper motor running at 18V dc to 60V dc at up to 3.5 Amps. They also put out 64 microsteps per full step or 256 steps per full cycle, for 12,800 steps per revolution for a standard 200-step motor, with a maximum step rate generated by the controller of 3 million microsteps/second.
Inforbix is leveraging its CAD and product data access technology to power up a free iPad app that lets mobile users search and access engineering data.
Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
