The VFD has single phase input. It makes it's own 3 phase to run the 3 phase motor.
I checked VFD's to see if they make one for 1 phase in / 1 phase out. The only type I saw is for a DC brush motor. It has 4 wires. Two for the Field, and two for the Armature. We use 90 volt DC brush motors for 120 VAC, and 180 volt for 240 VAC.
These are common in low horsepower gearmotor applications, and somewhat expensive.
You are trying to do a class project of something typical in the industry. A 3 phase motor would be best.
You can get low horsepower 3 phase motors. Because you are only doing a demo and not driving anything, you can use a slightly bigger motor with a small controller. No more than a 1 horsepower.
