New STAC6 Stepper Drives offer sophisticated motion algorithms and increased levels of programmability. The drives offer current output up to 6A, direct ac input without a transformer, bus voltages up to 200V ac and software selectable resolutions from 200 to 51,200 steps/rev at speeds up to 133 rps. New DSP-based algorithms focus on anti-resonance technology, demand signal smoothing, torque ripple smoothing and microstep emulation for systems that require low step resolutions. Self-Test and Auto-Setup features measure and configure motor parameters automatically. Macro assembly language programming provides register manipulation, conditional processing, math functions, multi-tasking capabilities, plus pulse & direction and encoder following capabilities for electronic gearing.

For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
Green energy is being billed as a way to make communities that are energy deprived more self-sustaining. So it makes sense to use natural materials to create devices that harvest this type of energy. That’s the idea behind a hybrid wind/solar energy harvester made of bamboo that’s been developed by UVM researchers.
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.
