I thought I'd break this out as a separate thread instead of it being buried in my wide 9 refurb thread.
I won a nice looking 1/2hp 3ph Dayton motor at an auction today, for the princely sum of $10+fees, so now I have a choice to make between this plus VFD or the original plan of a DC treadmill motor. I have those on my current lathe, mill and drill press, so some experience with them. Never used a 3ph motor before.
Is 1/2hp a good size for a wide 9? My gut says yes, but I haven't had dessert yet, so.. Downside of the 3ph motor is that it's a 3450rpm motor, though that's about the same as a treadmill motor, give or take.
Recommendations for a VFD? Sensorless vector drive mode seems like a good idea and there are a few that have that for reasonable money. Needs to be 110V input. Worth worrying about a breaking resistor or is that silly with a threaded on chuck?
Also, what max spindle rpm is sensible for a bronze bearing SB headstock? That'll help me start thinking about pulley ratios.
thanks!
