With 20 percent higher output force across the entire speed range compared with previous designs, the G4 also contains the latest custom engineered plastic molded threads and an over-sized spline for a more robust and better life product. Another enhanced feature resulting in superior durability is the use of larger bearings for greater rotor support and higher axial load capability.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
