It's interesting to learn how magnetic efficiencies can lead to optimized motor performance. What about the frame/bearings? It'd be interesting to read more about the materials used to handle the small, high-speed bearing surfaces, and how heat is dissipated from these support structures.
I understand that a combination of solid film lubricants like MoS2 that sustain the bearing at low speeds and then transition to an air lubrication mode are quite effective at high speeds in reducing bearing losses. Bearing systems like these can give very long life as long as the air supply is clean and abundant.
Are any of the motors making use of air lubrication?
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.
