A wide belt sander is way more than just a motor when it comes to the power usage.
There are many switches and sensors that are also fed from the power source so even if you change the motor, there s no guarantee that the machine will even start up.

There are air pressure sensors that will not even let the machine start if there s no air pressure and if the power for that comes from the leg that s not connected to the wall, you re not going to have a functioning machine.

Ok I spoke to Jack yesterday afternoon and am planing on buying a 10HP VFD from him soon. The price is not cheap but it is my cheapest option at around $750 for the VFD itself and roughly $70-$100 import duties/shipping from Canada.

Can you explain a little more about how I would get the other aspects of the machine to work with my VFD? The sensors and air controls and such? Would buying this VFD not eliminate this issue? I know that I will probably have to buy a smaller VFD for the conveyer motor. Will everything work in this manor?
