I have no expectation that I'll ever use a 3 phase motor fed single phase.
I was just curious.

I have a 10 inch baldor pedistal grinder. It is 3ph and I have a
static phase converted hooked to it. It starts and runs but I have
never been happy with the amount of vibration. I am now wondering
if it will run smoother with a VFD. Is it worth hooking it up
to find out? or am I wasting my time.
