Video: Yaskawa talks Variable Frequency Drives
Control Engineering Content Manager Peter Welander talks with Yaskawa's Manager of Marketing Communications Neil Koepke about the benefits of using variable frequency drives. While Welander visited the Americas headquarters for Yaskawa in Waukegan, Illinois, Koepke showed three different types of motors in a demonstrator that was built jointly by Yaskawa and the Milwaukee School of Engineering. The demonstrator's first cell shows a constant speed across-the-line motor and its flow control is varied with an outlet damper. In the second cell, a three-phase motor, which is constant speed, operated across-the-line, uses a inlet-guide vein for the flow control means. In the third cell, a variable frequency drive operates a three-phase motor and the drive itself controls the airflow in its environment.

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.
