Would I personally try to repair or recommend that you try to repair that? Not a chance. I'm not saying you couldn't possibly figure out a way but are you going to go through all the trouble of taking it all apart and putting it back together just to find out it's gonna maybe not work at all or burn up again in 2 months and give up the ghost when you need it the most? Find your closest Grainger's. They've got all kinds of motors, you can even buy the cheap one although the expensive one IS the better choice.
