Autosyringe (the product associated with the US patent number that I referenced above) was one of Dean Kamen's early inventions. It uses a step motor in the manner that you described. Dean purchased step motors and controllers from Hurst Mfg. (see the link in my earlier post) during the autosyringe development. When I introduced him to Dennis Hurst, the developer of those step motors and controllers, many years later at an FRC Kickoff, Dean shook his hand and said, "Thank you for making me rich."

BTW, the Hurst step motor controller still works very well.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
