How do I match a VFD to an AC motor?
Generally, just match your VFD power rating to your motor power rating. Your VFD shouldn't be widely larger than your motor rating, but a 2HP VFD would drive a 1HP motor.
The higher input voltage will ...

Will this pulley system work?
Yes.
If the motor moves to the right by distance $x$ then the inner left pulley most move the same distance.
This will increase the length of the fixed end by $x$ and the length of the top left ...
