Your primary winding is shot. Electric motors have a primary and secondary winding. the primary starts it spinning, the secondary keeps it spinning. If your blower will run after you spin it with your fingers, the primary is burned out and the secondary is good. You can rewind your coil at home, if you have the patience to count about 5000 turns. a rebuilt electric motor is one where someone burnished the commutator and replaced the brushes and springs. You can do that yourself and it will last a while. Use emery cloth to burnish the commuttor and clean it well with alcohol before reassembling. However, becaue your motor ha a burned out primary, 'rebuilding' it won't make it work unless you rewind it.
That would be for an induction motor not a DC motor.
