Motion controller can rejuvenate your machineIn this sawmill log kicker application, the motion controller swings the arms at high speed when they are not in contact with a log, then decelerates to move logs into the sawmill. Image courtesy of Delta Computer Systems for Control EngineeringAdding an electro-hydraulic motion controller can increase machine productivity. PLCs typically do not have instruction sets that are tailored for this function, and machine scan times can vary from scan to scan, making it difficult to deal precisely with feedback information. Old machine can add new life with a motion controller retrofit. See more photos and motion control diagram.

Cover story: Energy - Efficient Electric Motors - Graphic shows how higher efficiency motors save money. Source: Baldor and Control EngineeringHow to get the most out of energy-efficient motors: You have to do more than just look at the motor nameplate to get maximum energy savings. Are you ready for Dec. 19, 2010, the next major U.S. motor efficiency compliance deadline? Those truly interested in increasing efficiency will take a holistic view of overall machine design. Here's how to get inside motor efficiency to maximize savings.

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.
