My application is a single phase 5HP motor on a 1947 DeWalt, model GE, 16" radial arm saw - this info for any tool guys .
The motor spins freely for 2.5 minutes after removal of power. For convenience only, I'd like to stop it in 5-10 sec.
I have tried DC injection, using up to 24V @ 20A (the limit of my available DC power) with limited effectiveness. It works quite well when the RPM is very low, but it takes a while to get down from 3450.
I apologize if I missed this topic in my search of posts. It seems I scanned several thousand but could not find anything specific. There's lots of info for doing this with 3Ph and VFDs, but alas, I have neither. If someone wouldn't mind directing me to a thread, I'd be most appreciative.
