Question about Bosch Electric Table Saws
The motor didn't come up to speed anymore. It would come up then drop down a little. Then after a while it started sparking. I replaved the brushes but it still sparks.
If you already replaced the brushes you could have a couple problems, the least is the armature commutator needs cleaned and the more expensive is that it needs replaced. This is a problem unless you want to tackle taking the motor partially apart. Let me know what route you want to take either a repair center or looking at the commutator.

The electric field if depends on model the sliding contacts could be worn look good if it sparks on one side more the the other side replace the electric field allways first if both sparked the same it could be also thermal short in the armature
