A good article with nice details! Thanks. I really liked the graphics and the text overlays that expand upon what we are seeing. It looks like a rational approach that is both economical and well thought out. I wonder now how I can use this in other applications..

A very informative article . The graphics are superb. I believe this back EMF is also used in brush less DC motors in a sensor less commutation control.

Nice article, but would it be possible to put in a link to the full figure 2 diagram...the 2 parts are different scales and not easy to stitch together.

If anyone else is interested, the full diagram for fig 2 is Fig 7 in the L9942 data sheet at http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/DATASHEET/CD00072898.pdf

Is there any explanation of how the current profile lookup table works that someone could point me towards? I have read the entire datasheet 1.5 times ;) It gives no hint as to what values to fill the registers with. Thanks

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
