MOTION CONTROL:Yaskawa recently announced the release of the new Sigma Trac SGT series of linear motor actuators. Sigma Trac integrates the company’s linear motor components into a factory engineered and assembled linear actuator. Yaskawa’s original Sigma Trac design (STF Series) was introduced in 2002. Since then, they have received a considerable amount of feedback from the field regarding this product family. Over the past two years, they worked to finalize this new Sigma Trac design to accommodate the requirements we have seen in the majority of applications. The result is a new Sigma Trac design (SGT Series) which has all the following features and benefits:
• Factory assembled, fully integrated linear motor driven slide design reduces machine design complexity and commissioning time.
• Automatic motor recognition by Yaskawa amplifiers eliminates the need for user to input motor coil parameters
• A wide variety of stroke lengths, extremely high top speed and acceleration capability, smooth motion and accurate positioning
• Large integrated cable carrier allows space for peripheral cables and hoses
• Covers and additional accessories available
• Manufacturing at our ISO-certified production facility in Buffalo Grove, IL ensures a high degree of quality and introduces the possibility of customer specified minor modifications to the product
• Quick Ship Program for popular actuator sizes and lengths
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
