Bosch Table saw motor speed

[versanissan]

I have a bosch table saw that I am having problems fixing...
Several months ago the bearings went bad so I replaced them along with the brushes. Recently it has started to run at higher RPM and the brushes are arc heavily. I replaced the brushes, armature, speed control and bearings. It is still running at higher RPM and the new brushes are arcing again. The only thing I have not replaced is the field.
Any suggestions???
