Field-oriented control optimizes industrial motors Design How-To 9/25/2006 Post a comment Variable-speed drives for three-phase motors are ubiquitous components of industrial systems that help save energy and optimize performance. Traditional, scalar control techniques for variable-speed operation of three-phase electric motors offer simple implementation but limit the achievable performance. With a scalar drive, algorithm limitations can mean that meeting dynamic response specifications requires choosing a larger motor and a larger drive to complement it. That tends to drag down eff
50-nm device revs NAND race Teardown 9/11/2006 Post a comment The highly competitive NAND flash market just got tighter, with the introduction of IM Flash Technologies' newest device, a 50-nanometer, 4-Gbit offering.
Camcorder sets sights on sports Teardown 9/4/2006 Post a comment
By eliminating the optomechanics that have dominated the video camera media paradigm for so long, Samsung has developed a flexible, multifea tured camcorder that folds up into a neat little package measuring a mere 10 x 3 x 5.8 cm, about the size of a cigarette pack. In sharp contrast to the
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
