Had a similar experience. Can't remember the brand, (it's Red), but 80 gallon upright, only a couple years old, hobby use. Motor stopped working, started smoking. Poorly made windings let loose, shorted out. Found replacement motor at Grainger. Pricey, but easy swap. At least Grainger has full 1 year warranty, more if you want to pay for it. I think their no-questions-asked warranty replacement is pretty good.
Pulled the two capacitors off the old motor, just in-case.
Annoying.
