EISA has far-reaching implications for many industries — with 300 pages worth of goals and mandates, and new laws to increase the efficiency of a wider range of motors than ever before. More specifically, the law affects all engineers that specify or purchase electric motors, as well as those responsible for motor-powered plant operations. In some cases, the physical size and design of motors are also affected. Read more at Motion System Design's EISA page. |

nd in an hourglass may appear to fall smoothly, but its flow — and that of other granular materials — is surprisingly tricky to model. From a distance, sand resembles liquid, streaming like water. Closer inspection tells a different story: Individual grains slide against each other. Now, MIT researchers have developed a model to describe the behavior.
kening the glory of communities in the U.S. (and their manufacturing presence) goes beyond the physical. Essential to repurposing structures is the tidying of property records — a task increasingly falling to public authorities known as landbanks, which collect, manage, and then release foreclosed property for reuse.
Even machine builders currently serving only North American manufacturers benefit from adoption of late-2011 universal safety standards, and are better prepared to pursue global customers in the future. For machine builders who haven't yet made the transition, they could be missing out.
