My 24" SCMI bandsaw has a 3 phase motor that I use to power with a shop rotary phase converter. It's close to a 12" Northfield jointer that also is 3 phase powered. I generally have to plug/unplug one or the other to use them. I was thinking of powering the bandsaw with a VFD and single phase 220VAC so as not having to make the switch. If there is an advantage of having the option to run the bandsaw at a different speed it would make my decision easier to make considering the expense involved. The SCMI bandsaw is for woodworking not metal working so it's already running at an appropriate speed.
