If the motor ran very well, it would probably be a good idea just to replace the arm. You will probably find that it has simular performance to what it had originally. If you over heated the can in the process of killing the motor, it would also be a great idea to re-zap the magnets, too. Heat kills magnets.
Be sure to clean everything really good before reassembly. I like to use dish detergent to scrub things clean when doing full re-build. Use a com stick to clean out the brush hoods, too. Most of the power gets transferred to the brush through the brush hood, not those little tiny shunt wires that stick out the back of the brush.
If you don't want to complete the rebuild yourself, motor builders/tuners like Team Kwik
will complete the full task for you for a minimal fee. Definately worth the price of admission.
