I wasted a lot of time and money on cheaper static phase converters trying to run my woodworking stroke sander. Both made it work, but it sounded like a freight train and I knew I was tearing my 3-phase motor apart.
Then I found American Rotary. WOW, that’s what my sander is supposed to sound like. Full power, fast start-up, super quiet. It did exactly what you promised.
Now I’m off and running with my backlog of wood projects.
