This system integrates a NEMA 42 high torque brushless motor with drive and control electronics, promising a high starting torque, built-in regeneration circuitry, high positioning accuracy, stability at low speeds, and no dithering at zero speed. It allows greater inertia mismatch and doesn't need tuning. Standard industrial circular connectors and cordsets can connect to the product. Accessory cables include an in-line RS-422 converter for parameter setup, to connect to a PC's USB port, a PVC-jacketed cable with foil shield and unconnected drain wire, and a PVC-jacketed cable with IP68, NEMA 6P rating. Options include input voltage of 120 or 240 VAC; two motor lengths; internal or remote encoder; control knob for manual positioning and integrated planetary gearbox.
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.
