By taking advantage of new manufacturing processes that reduce cost while
improving performance, Kollmorgen Motion Technologies Group has introduced a new
line of standard-model, direct-drive linear motors. Evolved from
customer-specific designs, the PlatinumTM Direct Drive Linear (DDL) Series will replace traditional mechanical assemblies such as belts and pulleys, ball screws, racks and pinions. The consistent demand for linear motors across a wide range of markets," comments Director of Engineering John Floresta, "is requiring that these motors become standard general-purpose devices that are less costly, have the highest possible performance, and are easier to implement, both mechanically and electronically."
To achieve these objectives, the Platinum DDL Series motors consist of two constructions. The Ironcore motors feature a high-rated force-per-frame size, and a patented anti-cogging design without the need for magnet skewing. Peak force of the Ironcore motor is 300 to 8000N (67 to 1800 lb-force). Alternately, the ironless motors have no attractive force between the coil and magnet components. They also exhibit zero cogging for smooth operation. Peak force of the ironless motor is 120 to 800N (27 to 180 lb-force).
Matching the Platinum DDL with Kollmorgen's ServostarTM digital amplifier," Floresta adds, "ensures maximum system performance."

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
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.
