acceptance criteria for syncronous machine slip ring scratches
(OP)
We have a syncronous machine. Manufacturer requires < 10 mils runout on slip rings.
Does anyone know what level of scratches on slip rings (caused by work near slip rings) is acceptable?
Would 10 mil deep scratch be acceptable? Any thoughts or references?

However, what does concern me is the run-out.
10 mils better be for a low RPM motor (below 600 RPM)
