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?
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.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
