[QUOTE="Guineafowl, post: 6044308, member: 539397"] I was wondering if a higher temperature version of that plastic technique is used to melt the varnish at the point of contact. Several adjacent segments have a resistance of 1.88 ohm, +- 10%. Others have anything from 11 to 300 ohm. It’s a very crappy motor. Normally, I test a commutator by seeing if adjacent, then opposite segments have consistent resistance. Here, I’m not sure - the arcing suggests shorted windings, but maybe the heat is from the high resistance connections at the commutator tabs. No, sorry. The mixer is back together now - it’s beyond economical repair (manufacturer is based in a small village in India). [/QUOTE]
