That motor is single phase, and 2 speed.  It has extra windings, that is why 
it is so heavy.  You do not want to part with that motor because it will 
give you twice as many speeds on your headstock as a single speed one will. 
You can better match your speed when cutting. Really good when youa re 
facing a large piece and need to slow down the speed on the outer cut to 
keep down chatter.  I have a 3 hp one in my Colchester lathe.  It burned out 
about 2 weeks after I got the lathe, and it cost over $300 to have it 
rewound since it is 2 speed.  However, it needs the 2 speed due to the way 
the lathe is set up....

If  the tag states it will run on 115volt it is NOT a 3 phase unless it is 
an oddball military surplus unit.... 2 get 115 3 phase you have to 
transformer down to 115 with a 3 phase transformer.  3 phase is 230/460 
USUALLY..  there are other configurations....
