Motors prevent corona damage
Electric motors constructed specifically to ensure reliable operation when fed from variable speed frequency drives prevent the destructive phenomenon called "corona" from occurring.
Electric motors constructed specifically to ensure reliable operation when fed from variable speed frequency drives prevent the destructive phenomenon called "corona" from occurring. This damage exists to a greater degree when operating motors from pulse-width modulated inverters. The Simple Truth About Motor/Drive Compatibility details findings and solutions.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
