Thanks Ryland,
the comm condition charts are a great reference.
Those are the things I've done before too on motors we've rebuilt in the shop. I guess what I'm really wondering about is the additional things, if any, that I should be doing before tripling the rated voltage of the motor for EV use. I think Ben pulled the field coils right out of his and wrapped them in special tape. I've seen some guys adding extra banding and varnish to the armature and field coils. Are all those things necessary or precautionary? I know I will need to advance the timing if I go to 144 volts, but not sure what the voltage limit is before I have to advance it.
