FLUID POWER: KNF diaphragm pumps equipped with brushless dc (BLDC) motors offer advanced OEM control solutions for handling air, gases, or liquids. Their integrated “feature-packed” controls deliver precise pump performance in direct response to system requirements. The BLDC motors in KNF pumps are designed and manufactured exclusively by KNF to handle the high stresses associated with the reciprocating forces of a positive displacement pump and are consistent with the highest standards of engineering, reliability and quality.Compared with conventional dc models, pumps with BLDC motors from KNF exhibit low current draw, extended lifetime, and reduced EMI/RFI, while dramatically decreasing pump size, weight, and heat generation. Combining integrated on/off and speed logic signals with feedback and current-limit controls enables users to realize ideal performance and precision that can instantly be varied for OEM system demands.
KNF pumps additionally incorporate an exclusive structured diaphragm promoting high efficiency and flow and allowing the pumped medium to remain pure and contaminant-free. Depending on model, end vacuums up to 29.86 inch Hg (< 0.5 mbar) are achieved using only two stages to yield reduced cost, size, weight and power requirements.
These BLDC pumps provide safe, oil-free operation without maintenance and can be developed to accommodate the widest range of OEM applications. Custom materials, windings, finishes, coatings and value-added options can be specified to meet particular demands. Small-batch quantities can be ordered and all pumps are supplied ready to mount in any position.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
