Ryan--Excellent post. My company recently installed a Cartesian robotic system that uses steppers for positioning a dispensing head providing a bead of RTV. I definitely wish I had your post prior to investigating this project. Being a mechanical engineer, there always seems to be some "magic" relative to electrical engineering and certainly electronics. Topics such as this one really gets to the basics in quick fashion. Again, good post.
Thank you for your positive comments. These solutions not only save time, but save money with a high level of analog integration and just enough digital integration to take the burden off the MCU. Two things we all wish we had more of: time and money!
Excellent post. Thanks for the entertaining explanation for how integrated motion solutions play out with steppers and BLDC motors. It's easier to simplify when motion control can be reduced to the component level and integrated capabilities. Thanks for the update.
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.
