How about an eddy current magnetic speed brake? Powerful magnets moving close to a thick piece of copper ought to do it. https://www.youtube.com/watch?v=sENgdSF8ppANo power required, the right design should bring the impact wrench to a fast stop once the air is off.

If you go back to steam engines the two weights swung out and shut off the pressure to the engine to keep it from running away. I'm not sure I could fit something like that in that space but I had an idea like that. Occasionally, until I solve that problem the socket goes flying off too. The square shaft of the wrench is hardened and I've used a Dremel to create a dimple but it's not deep enough yet. Adding a guard around the socket for safety is a good idea then. And if centrifugal force causes two arms with brake pads to fly out and run against the guard to slow it down that would work. But seems overly complex. Using that same guard idea but with pads that apply load to the socket to keep it from spinning away might be easier. If you think about the sound of an impact wrench it spins up and only when it hits a load do you get the hammering sound. I've been considering this as a solution instead. https://www.aliexpress.com/item/4000220757109.html _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
