That is a generic fan motor. The easiest thing to do is to haul it to your local AC supply house or Grainger.

You may have to cut the shaft.

If you want to buy on line, cross ref the number on the motor. That is NOT the original motor. AO Smith is a brand of replacement motors used in the AC industry.

Easy to see why the motor was overheating with all the dust in the openings. You might think about replacing the other motor while you have the unit out.

I bought one online last night..  there is only 1 motor in this smaller unit. There isn’t much online about this 1301 unit.  All of the manuals are for the bigger 2702 unit which I haven’t gotten to yet.
