In the first of several planned extensions, Rockwell Automation has expanded the power
range of its Allen-Bradley PowerFlex 755 AC
drives to 450 kW/700 hp, providing users with increased application
flexibility. Featuring advanced diagnostics and a convenient roll-out design,
the PowerFlex 755 AC drive is suited for motor control applications in a variety
of heavy industries, including oil and gas, tire and rubber, refining, material
handling, metals and mining.
A key feature of the PowerFlex 755
extended power range drive is its roll-out capability, which allows easy access
to the drive for fast installation and maintenance. The drive's modular design
helps simplify replacement of drive components, such as cooling fans, circuit
boards and major subassemblies.
The PowerFlex 755 drive comes equipped with an embedded Ethernet port
and five option slots that allow users to tailor the drive to best suit their
application. Options include I/O, feedback, safety, additional communications and
auxiliary control power input.
PowerFlex 755 now supports Rockwell Automation Integrated Motion, allowing it
to be configured and controlled using motion profiles and instruction sets in an
Allen-Bradley ControlLogix controller with Rockwell Software RSLogix 5000
software. The ability to support variable frequency drives, motion drives, I/O,
smart actuators and other EtherNet/IP-connected devices on a common network
helps increase design flexibility, improve system performance and reduce
power range extension expands the PowerFlex 755 AC drive offering from 0.75 kW
(1 hp) up to 450kW and 700 hp at 400/480V ac input.

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
