hey, i have another question if anyone would like to reply. i posted "OT
commutator wear" on 6/24/07, finally got around to working on this inverter
again. removed the armature (to bring to a electric motor shop) to get the
slip rings smoothed out and saw these (two, one on each end) blobs of what i
assume is JB weld on the windings. my first thought was one of the previous
owners put them on there to disguise damage or to cover up a jerryrig repair
job (is it possible to solder broken armature wires?). my second thought
was maybe they were applied at the factory to balance the amature. i have
no idea. asking you guys.

My bet is that it was used to balance. I would think that if someone
repaired the winding (which does happen) that person would have minimized
the size of the blob.


I am apprized to see a commutator in a RPC though.
