Courtesy: Rockwell AutomationRockwell Automation has extended the ratings of its Allen-Bradley PowerFlex 755 AC drives to 1500 kW/2,000 hp. The high-power drive builds on the application flexibility and common user experience of the PowerFlex 750-Series, providing industries with a new option for advanced power control.

The PowerFlex 755 drive is well suited for a wide variety of applications ranging from simple variable speed and variable torque control to the most demanding systems requiring constant torque control. Target applications include fans, pumps, mixers, compressors, conveyors and extruders, as well as applications for the oil and gas, tire and rubber, refining, metals and mining industries.

The latest frame extension delivers the enhanced control capabilities of earlier high-power models, including features, such as 400/480/600/690 volt ratings and N-1 technology. With N-1 technology, users can configure the PowerFlex 755 high-power drive to utilize one, two or all three of its power structures. This gives the redundancy and advanced control needed to effectively manage load changes, protect equipment, and keep the drive up and running in the event of a power failure. 

The power-range extension is one of several enhancements to the PowerFlex 755 drive designed to provide application flexibility. Additional features and benefits available include the following floor-mount drives and dual-port EtherNet/IP option module.

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.
