Yes the original pully was with it.While not difficult, any motor swap is likely going to involve fabricating some sort of adapter plate as your replacement motor will be smaller than the previous motor. If you can do that just once it'll save you some work. I and others here have had good luck with TECO VFDs. Did you get the pulley from the old motor?
I did some reading on North American Phase Converters website. It states that "A North America static phase converter will only run motor loads. Because it does not produce a constant 3rd leg of power, a static converter will not run a resistive or inductive load." Looking at the lathes electrical drawing it shows 3 phase incoming power going to the main motor and the coolant sump pump. A transformer then reduces voltage to 110V to power the relays and other circuitry. If I were to use a static converter, the transformer would need to be removed from the circuit and 110V power supplied to the remaining circuit, and I would be using the static phase converter strictly for the two motors. I do have a local "scrap yard" that buys surplus industrial electrical equipment. He has 3 phase motors fairly cheap, North American sells just the control panel for their rotary phase converters and the end user supplies the idler motor. This would be an affordable option.The problem with the VFD is you need to modify the circuitry in the lathe itself since VFD’s need to be directly connected to their loads (motor) without any switches in between.
It’s an awesome setup @mksj can help with it but a static converter is cheap and you can just hook it up to the main power input for the whole machine and start using it.

Question: What would be the turning limits of say a 3, 5, and 7.5HP motor? Is it dictated by stock diameter, depth of cut or mass?
At this point the largest project I have planned is a 12"x2" round bending die for building roll cages.
Yes it came with a slide in chip pan, and a rear mounted chip catcher, which unfortunately was bent by the forklift operator who loaded it on my trailerIs the chip pan around anywhere? They slide in and out like a drawer.
