Another option of you don’t need the full 10hp at your disposal would be a 2pole (~ 3600rpm) 7.5hp motor for around $500 plus a new drive sheave and appropriately sized belts to keep the sanding belt at the proper speed. A $100 VFD could be used to control the feed motor and the rest of the electronics are either 120VAC or 24VDC and can be rewired as needed. Most step down control transformers have multiple taps and are only pulling from two legs of the incoming 3ph power, since you’ll have two legs with 1ph it won’t be a problem (but won’t necessarily be easy) to rewire it to maintain function of all the controls.
