Default I need to run this motor on single phase. (with photos)

60 year old noob here. A lifetime of mechanical knowledge, but AC motors . . .
not so much.
I basically inherited this motor on a vertical air compressor. No capacitor, four wires, and out of a shop that had no 440, this must be a 220 three phase motor. Am I right so far?
I can see on the nameplate what I believe to be HP (5), RPM (1725) and not much else makes a lot of sense to me.
Of course, I have single phase in my shop.
Is there a practical way to wire this puppy up? As in a static or rotary phase converter? The compressor is worth maybe $1000, so I must keep that in mind.
I am looking for thoughts, advise, experience, etc. Any contributions will be deeply appreciated.
