Schaffner's new line of chokes come in a range of inductance values up to 90 mH and currents up to 5A. Vertical EV chokes have a narrow width, and the EH horizontal versions have a low profile. Designers can mount circuits densely due to low magnetic leakage flux. Unexpected resonance problems are prevented with a stable frequency response through broadband attenuation characteristics. They have a flammability rating of UL94-V0, and have operating and storage temperatures of -25C (-13F) to 100C (212F). They weigh 10-70g, and have a maximum operating voltage at 50 degrees of 250V. They also offer a power operating frequency at 50C (122F) of dc to 400 Hz, a maximum resistance tolerance at 25C (77F) of ± 15 percent, and an overcurrent of 1.5 x Inominal for 60 sec, once every hour.
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.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
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.
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.
