With the popularity of fuel cell technology rising, so too is the decision to use a brushless dc motor for fuel cell applications. Not only does a brushless motor remove the need for dc to ac inverters, the absence of brushes completely eliminates the risk of arcing or sparking. Compared to brush dc motors, these have a longer lifespan, and some would even consider them to be nearly maintenance-free. The motors also feature integrated electronic capability, wide dynamic speed range that reduces power consumption, and high efficiency.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
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.
