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
The Other Tesla David Blaza5 comments I find myself going to Kickstarter and Indiegogo on a regular basis these days because they have become real innovation marketplaces. As far as I'm concerned, this is where a lot of cool ...
