Sunset,

Why do you say that?
The 3-phase motor I got is the same HP as the original single phase motor and I'll be using the same belt and the same pulley, if I decide to turn down the motor shaft.

I went from a 1.5 hp single phase to a 2.0 hp 3 phase on my lathe with no problems at all. With the VFD ramping up the motor speed on start, it's not like you are doing a "hole shot" off the line with twice the normal torque output.
