Ouch.. it is usually fatal when you let the magic smoke out of a motor. Couple of questions.. what kind of motor is it and do you have any pictures of the ‘guts’? I doubt it has brushes since it is an external motor with a belt drive, but you never know. The absence of a capacitor typically indicates that it has a centrifugal start switch internally, which would not cause the problem you describe. When you say you couldn’t turn the wheels, can you turn the motor by hand freely (with the belt removed?). That would at least indicate if it is the bandsaw or the motor that is stuck. If it’s the motor, then chances are your bearings/bushings are toast.. which would in a lot of cases allow the rotor to make contact with the windings and cause a short. If it has bearings, they are pretty easy to replace.. if it has bronze bushings with felt packing around them, they are a PITA. If the motor turns freely, then an ohm meter can help determine if the windings are shorted. Give us some more info and maybe some pictures..

Cheers,
Brad
