Integrated variable speed motor control
Grundfos' unified MLE motor is suited for new commercial HVAC/R applications and deep retrofits and is available in models, ranging from end-suction to inline to split-case pumping solutions.
Grundfos' unified MLE motor is suited for new commercial HVAC/R applications and deep retrofits, and features ranges of 3 to 30 hp for building services. Grundfos will make the unified MLE motor and variable frequency drive (VFD) available in multiple models, ranging from end-suction to inline to split-case pumping solutions. For decades, Grundfos has manufactured its own MLE motors to match its energy‐optimized, high performing pumps. Now Grundfos is expanding that effort to include motors sizes that are well suited to HVAC/R applications. These Grundfos products provide a systems approach, which, through intelligent technology, adapts precisely to current demand to deliver performance, energy efficiency, and reliability. The integrated, energy‐optimized MLE system consists of a sensor, system controller, VFD drive, and standard asynchronous motor all in one.
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.
