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

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
