Made to keep up with higher reliability and smaller space demands, this new series has a protection circuit against the load short or open operation, and a space-saving built-in resistor for current sense. The peripheral circuit design is simpler with a common interface signal and series pin compatibility. The series is more reliable with a built-in motor coil, short and open-circuit protection, and varied lout lineout (1 A, 1.5 A, 2 A, 3 A). Clock-in topology reduces control signal wire and micro-computer load, with ICs built into a logic circuit to control excitation switching and D/A converter. The series has both microstep type and full/half-step type. Unlike other motor drive series, the SLA7070M is designed to make pin alignments and interface specification compatible.
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.
