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
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
