Series of miniature servoamplifiers are for dc and brushless dc motors and incorporate custom mixed analog/digital ICs and a hybridized power stage. The basic configuration is a current mode amplifier, and no trimmers are used in the basic version. The products meet UL508c and the relevant CE regulations. The power stage is implemented on a single ceramic substrate, and this design enables high thermal conductivity, high current carrying capacity, and mechanical strength.
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.
