Can triac controller be used for controlling the speed of a vacuum motor (carbon brush)?

Triac controllers "Payne Engineering 18TB, Harbor Freight or other router speed controllers" will work but bay be a little less sensitive in the lower speeds. These are meant for more or less resistive loads "Hot Wire etc." But will work on the universal motors. If that is all you have access to just wire a simple incandescent light bulb in parallel with the output and it will stabilize the lower output voltages.

I have a TRIAC contoller I built that will handle 60 amps on 240 1phase. It includes coarse and fine adjustments. Works perfect on the oscilloscope but haven't hooked it up to the bench yet. If all works out I will try to come back with the schematic and BOM. It may be a while since I only log in here once every couple months or so (just to see if there's some cool new thing I've missed)

that sounds very exciting paul ..maybe a solution for starting a 4hp 3ph motor on single ph .?
