Describe how you determined that the motor 'burned out'... IIRC, that is a universal motor attached to a variable speed board. If it just doesn't run.. it could be brushes, dirty commutator, fried control board or any number of other things. I'd initially look into determining the cause of failure, doing a little troubleshooting first. Typically, those replacement motors are more expensive than the machine itself, and it would be a shame to fork out that kind of money only to find out that it was a bad speed board or something else.

Thanks, Brad. The motor does not spin freely, very rough. When I wire the motor directly to power it sparks, pops and smokes. Circuit board is clean, no burn marks.

 

Well, since you have already written off the motor, crack it open and check it out. From the description, it sounds like it needs some new bearings. Putting on the new belt too tight probably accelerated their demise. I would be careful hooking up the motor directly to power unless you know exactly what kind of power it is expecting and have it available. Don't just go plugging it into a wall outlet

Cheers,
Brad
